ABSTRACT
The research is studied the Suvarnabhumi Airport’s international passengers
satisfaction in service quality by comparing expectation and perception. The objectives
of the study are to study the factors that have an effect to international passengers
satisfaction on their expectation and perception in service quality of Suvarnabhumi
Airport and also to find out the overall Suvarnabhumi Airport’s international passengers
satisfaction level in service quality by comparing passengers expectation and perception
that effected on their satisfaction. The research methodology was a survey method, by
collecting 342 questionnaires from international passengers who ever use services &
facilities at Suvarnabhumi Airport, both of male and female, who aged over 18 years
old. After that the questionnaires were analyzed by using frequency, percentage, mean
and standard deviation. Moreover, t-test and ANOVA were conducted for hypotheses
testing at the confidence level of 0.95.
The results illustrated that most of respondents were male, aged between 18-29
years old with non-Asian nationality. Most of them were single, had education level at
bachelor’s degree and had total annual income for the previous year between USD
25,000 – USD 49,999. Mainly respondents also have used Suvarnabhumi Airport since
it opens for 1-5 visits. The factors that have a significant effect to international
passengers satisfaction on both of their expectation and perception in service quality
were age, nationality, marital status and experience. While the education factor has an
effect only on perception and income factor has an effect merely on expectation. In
contrast, the gender factor doesn’t have any effect on both of expectation and
-

perception. The overall international passengers expectation was in very good level
while overall international passengers perception was in good level. Therefore, the
overall international passengers satisfaction level was dissatisfied in service quality of
Suvarnabhumi Airport.
This research is recommended that Suvarnabhumi Airport should be more
concerning about the services and facilities for the variance of passengers, more Public
Relation to acknowledge passenger about airport information, more efficient officers who
are able to use English fluently and know the whole services and facilities to inform the
passenger and also more transportation efficiency.

CHAPTER 1
INTRODUCTION
Introduction and statement of the problem
When we talk about Thailand’s airport in Bangkok for the last previous years,
everyone knew that it refers to “Don Muang Airport” which is located on Vibhavadi
Road. Since September 28, 2006 Don Muang Airport becomes the history when
“Suvarnabhumi Airport” has been replaced with much higher performance in term of
infrastructure, facilities, exhibition complexes, and etc. With the high capabilities in
several ways, Suvarnabhumi Airport has become “The Aviation Hub of Southeast Asia”
that every country keep an eye on because this project is a national priority of the
government and it is also the huge investment of the country with long period
preparation and construction.
On the opening day, a lot of problems showed up. Starting with computer
crashes at several check-in counters, leaky roofs and delays in getting baggage from
the airplanes to the departure terminal, these seem to be normal for the first day
glitches but there still got so many problems until now and it absolutely takes time to
solve the whole problems.
Suvarnabhumi Airport is a great opportunity to build a reputation, the highest
international standard, and to generate additional substantial revenue from financial and
commercial services including retail and entertainment businesses in airport area. Thus,
-
2
Suvarnabhumi Airport has a great impact to Thai’s economic and image directly. Then
the existing problems are also the negative image and significant problem for
contribution to its attractiveness as a major aviation hub as well.
For above reasons, it is very interesting to measure the satisfaction level in
service quality of international passengers who use Suvarnabhumi Airport for
developing the quality of international airport service.
Objectives of the study
This study is intended to
1. Study the factors that have an effect to international passengers satisfaction on
their expectation and perception in service quality of Suvarnabhumi Airport.
2. Find out the overall Suvarnabhumi Airport’s international passengers satisfaction
level in service quality by comparing passengers expectation and perception
that effected on their satisfaction.

Delimitation and Limitations of the Study
1. Suvarnabhumi Airport is quite novel for research. There are no any
researches related with services & facilities directly.
2. The research cannot refer to the whole passengers satisfaction with 400
sampled international passengers.
3. Construction problem may effect to the passenger perception.
Expected Benefits
1. The international passengers satisfaction of Suvarnabhumi Airport and
acknowledging the results to related organization for improving the services
that passenger dissatisfied.
2. The factors that influence on international passengers expectation and
perception in service quality that leads to passengers satisfaction.
Definition of Terms
Passenger is the non-Thai consumer who uses services & facilities at the
Suvarnabhumi airport in term of passenger.
Expectations are beliefs (likelihood or probability) that a product/service
(containing certain attributes, features or characteristics) will produce certain outcomes
(satisfaction/dissatisfaction) given certain anticipated levels of performance based on
previous affective, cognitive and behavioral experiences.
-
5
Perception or perceived service quality is the consumer overall attitude or
judgement towards the excellence of service.
Satisfaction is the state felt by a consumer who has experienced a performance
that has fulfilled his or her expectation.

CHAPTER 2
REVIEW OF LITERATURE
The study of Suvarnabhumi Airport’s international passengers satisfaction is
studying the factors that have an effect to international passengers satisfaction on their
expectation and perception in service quality of Suvarnabhumi Airport and find out the
overall Suvarnabhumi Airport’s international passengers satisfaction level in service
quality by comparing expectation and perception that effected on their satisfaction.
Thus, understand customer expectation and perception first, then figure out the
customer satisfaction level and that will illustrate which demographic factor effect to
customer satisfaction.

1. Suvarnabhumi Airport
Suvarnabhumi Airport, the New Bangkok International Airport, has been opened
for commerce since September 28, 2006 with high capacity of 45 million passengers at
the opening day and 100 million upon full development and high potential both of
services and facilities. Moreover, the airport uses the Airport Information Management
System (AIMS) to support and coordinate all interconnected systems in the various
buildings of the airport. (See appendix A)
Thus the Thai government designates this airport to be the aviation hub of
South East Asia with the international airport standard provided including service
quality.
2. Service Quality
Service quality as a measure of how well the service delivered matches
customers’ expectations (Lewis and Booms, 1983; Tony and Stephen, 1997) or is the
importance of customer perceptions of quality (Takeuchi and Quelch, 1983; Tony et al.,
1997). The perceptions are as an attitudes or judgements made as a result of
comparisons drawn by customers between expectations of services and their
perceptions of service performance (Berry, Zeithaml and Parasuraman, 1985 and 1988;
Grönroos, 1982; Lewis and Booms, 1983; Tony et al., 1997). In fact, it seems perceived
the quality of service is a function of the gap between customers’ desires and
expectations and their perceptions of the service that is actually received (Parasuraman,
Zeithaml and Berry, 1985; Tony et al., 1997).
-
8
The idea that perceived service quality results from a comparison of expectation
with perception of performance would seem to imply that perceived quality equates with
satisfaction. As a result, if a customer is satisfied then there is quality of service.
For defining the service quality, there are four factors which differentiate
services from material goods: (Kotler and Armstrong, 2001:317; Lerluck, 2005)
1. Intangibility The services could not be seen, tasted, felt, heard, or smelled
before they were brought. For example, airline passenger had only a ticket and
the promise that they and their baggage would safety when they arrive at the
intended destination.
2. Heterogeneity The quality of services depended on who provided customer as
well as when, where and how they were provided. For example, at the
international airport that had reputations for international airport standard
services and facilities. The group of passengers who line in channel A perceived
the good service quality from 5 years-experienced employee while another
group of passengers who line in channel B perceived the worse service from 2
months-experienced employee. It means the passengers perceived the different
service quality from the different skilled employee.
3. Inseparability The services could not be separated from their providers whether
the providers were people or machines. As long as the service employee
provides the services, the employee was the part of the service. Because the
customer was also present as the service was provides, provider-customer
-
9
interaction was a special feature of service marketing. Both the provider and the
customer influenced the service outcome.
4. Perishability The service can’t be stored for later sale or use.
These qualities make services high in experience and credence qualities, so
consumers have a more difficult time evaluating services than they do goods (Darby
and Karni, 1973; Zeithaml, 1981; Rushton and Carson, 1989; Jim and Julie, 2000).
Levitt (1983; Jim et al., 2000) describes a main characteristic of service as a promise of
satisfaction. As a promise, both implicit and explicit, made by service organizations
influence customers’ expectation of the service experience (Bitner, 1995; Jim et al.,
2000) and, because expectations are the standards against which customers evaluate
service quality, it is important to understand the nature of consumers’ expectations.
3. Expectation of service quality
Customer expectations are beliefs about a service that serve as standards
against which service performance is judged (Zeithaml et al., 1993; Peter and Vassilis,
1997); what customers think a service provider should offer rather than what might be
on offer(Parasuraman et al., 1998; Tony et al.,1997).
There are two levels of expectations, desired and adequate. Desired expectation
represent the level of service a consumer hopes to receive, a blend of what a consumer
believes “can be” and “should be” (Parasuraman et al., 1991; Tony et al.,1997), while
adequate expectations, a lower level of expectations, related to what consumer believes
an acceptable level of performance (Zeithaml et al., 1993; Peter et al., 1997). Desired
-
10
expectations are thought to remain relatively stable over time, while adequate
performance expectations may vary more widely. Between these two service quality
expectation levels is the zone of tolerance. Zone of tolerance is the extent to which
consumers recognize and are willing to accept heterogeneity in the provided service
(Zeithaml et al., 1993, p.6; Peter et al., 1997) Thus, a consumer expectation, rather
than having only one level, is bounded by upper and lower limits.
Individuals form service expectations on the basis of their past experiences,
word-of-mouth communications (with other customers, friends, family and experts), and
the explicit service promise (staff, advertising and other communications) and implicit
service promises made by service firms (such as price and the tangibles associated
with the service) (Zeithaml et al., 1993, Zeithaml and Bitner, 1996; Peter et al., 1997).
Perceived service quality has been defined as the consumer’s global attitude or
judgement of the overall excellence or superiority of the service. Perceived service
quality results from comparisons by consumers of expectation with their perception of
service delivered by the suppliers (Lewis et al., 1994; Takeuchi and Quelch, 1983;
Zeithaml, 1998; Peter et al., 1997). It means that the factor to ensuring good service
quality perception is in meeting or exceeding what customers expect from the service.
Therefore, if the perception of actual service delivered by the supplier lower than
expectation, a gap is created which should be addressed through strategies that affect
the direction either of expectation or perceptions, or both (Parasuraman et al., 1985;
Zeithaml et al., 1990; Peter et al., 1997)? And narrowing this gap might decrease the
-
11
expectations or increase the perceptions of what actually customer received or a little of
both.
4. Perception of service quality
There are four primary factors that influence the customer perception of service:
service encounters or “moments of truth”, the evidence of service, image and price.
These form the customer’s overall perception of quality, satisfaction and value (Zeithaml
and Bitner, 1996; Peter et al., 1997).
1. In service encounters Verbal and non-verbal behavior are as important
determinants of quality as tangible cues such as the equipment and physical
setting (Bitner et al., 1990; 1994; Grönroos, 1990; Zeithaml and Bitner, 1996).
2. Evidence of service Due to the intangibility of services and the simultaneity of
production and consumption, customers are searching for cues to help them
determine the level of service. Three major categories of evidence have been
identified:
- Employees - how they are dressed, their personal appearance and their
attitude and behavior
- Process – whether the service is complex, bureaucratic; and
- Physical evidence – all the tangible aspects of the service such as
equipment and physical facility that service is offered ( in this case, such
as passenger building, automated baggage handling machine )
-
12
3. Image and reputation The set of perceptions reflected in the associations held
in the memory of the consumer (Keller, 1993). These can be specific (e.g. hours
of operation, ease of access), or, of an intangible nature (e.g. trustworthiness,
tradition, reliability). A favourable image can influence positively perceptions of
quality, value and satisfaction (Grönroos, 1990; Zeithaml and Bitner, 1996).
4. Price If the price is high, customers are likely to expect high quality, and their
actual perceptions will be influenced accordingly. If the price is too low,
customers might have doubts about both the ability of the institution to delivery
quality and about the actual level of service received.
5. Measurement of expectation and perception of service quality
Parasuraman et al. (1985, 1988; Peter et al., 1997) and Zaithaml et al. (1990;
Peter et al., 1997) developed a multi-item scale (SERVQUAL). The SERVQUAL model
is a scale developed to measure service quality by computing the differences between
consumers’ desired expectations and their perception of a service firm’s performance
across five service dimensions: (Parasuraman et al., 1998; Peter et al., 1997)
1. Reliability, or ability to perform the promised service dependably
2. Tangibles or the appearance of physical facilities, equipment, personnel, etc.
3. Responsiveness, or a willingness to help customers and provide prompt
service
4. Assurance, conveyed by employees’ knowledge and their ability to
communicate trust and confidence
-
13
5. Empathy, the caring, individualized attention provided to the customer
Reliability which is the most critical service quality dimension (Berry and
Parasuraman, 1991; Jim et al., 2000) is the outcome and typically represents the core
service. While the other four dimensions represent the process of service delivery which
may be viewed as more secondary by consumers. Moreover, consumers may have
differing zones of tolerance for different service quality dimensions. Further, Zeithaml et
al. (1993; Peter et al., 1997) noted that consumers seem more intolerance about
unreliable service (broken, promises, service errors) than about other aspects of the
service.
Because reliability has consistently been found to be the primary influence on
service quality judgements, consumers may have more exacting expectations (i.e. a
narrower zone of tolerance) for the service outcome, or a core service. While several
attributes may be used to judge overall service quality, having a service representative
keep his/her promise seems more important than his/her friendliness or the cleanliness
of the service facility to such judgements. Therefore, instead of a single zone of
tolerance against which overall performance is judged, there may be a range of zones
that varies for different service dimensions, where some dimensions are more essential
than others to consumers. Besides, consumers may expect a higher minimum level of
performance for a more essential quality dimension (Zeithaml et al., 1993 Peter et al.,
1997)
The SERVQUAL model concentrates on five gaps (Parasuraman et al., 1985;
Tony et al., 1997):
-
14
Gap 1– between consumer expectation and management perception
Gap 2 – between management perception and service quality specification
Gap 3 – between service quality specification and service delivery
Gap 4 – between service delivery and external communication
Gap 5 – between perceived service and expected service
This study focuses on Gap 5: the difference between Suvarnabhumi airport’s
international passengers’ expectations and perceptions of service.)
The gap that may exist between the customers’ expected and perceived service
is not only a measure of the quality of the service, but is also a determinant of customer
satisfaction/ dissatisfaction.
Quantification is obtained by measuring expectations and perceptions of
performance for each one of these dimensions (Cronin and Taylor, 1992; Parasuraman
et al., 1988; 1991; Zeithaml et al., 1990; Peter et al., 1997) SERVQUAL was deemed to
be applicable to retail and business services and relevant for banking services (Zeithaml
and Bitner, 1996; Peter et al., 1997)
6. Customer Satisfaction
Customer satisfaction is the leading criterion for determining the quality that is
actually delivered to customers through the product/service and by the accompanying
servicing (Vavra, 1997; Abraham and Tayor, 1999). While WTO (1985; Abraham et al.,
1999) defined customer satisfaction as a psychological concept that involves the feeling
of well-being and pleasure that results from obtaining what one hopes for and expects
-
15
from an appealing product and/or service. Moreover, the most widely used is the
expectancy disconfirmation theory developed by Oliver, 1980 (Abraham et al., 1999).
According to this theory, customers purchase goods and services with pre-
purchase expectations about anticipated performance. When the product or service has
been purchased and used, outcomes are compared against expectations. If outcome
matches expectations, confirmation occurs. Disconfirmation occurs when there are
differences between expectation and outcomes. Negative disconfirmation occurs when
product/service performance is less than expected. Positive disconfirmation occurs when
product/service performance is better than expected. Satisfaction is caused by
confirmation or positive disconfirmation of customer expectations, and dissatisfaction is
caused by negative disconfirmation of consumer expectations.

Lerluck, Srichalee (2005) studied the satisfaction of Domestic Airline
Passengers Toward Service Quality of Thai Airways International Public Company
Limited
According to this study, the objectives were to study THAI passengers’ behavior,
THAI passengers’ perception, passenger satisfaction toward service quality on
departure and arrival service, and passenger behavior.
The research methodology was survey method, by collecting 392 questionnaires
from THAI domestic passengers. SERVQUAL model is applied to examine passenger
satisfaction in service quality.
-
16
The results illustrated that most respondents were female, aged 21-30 years
old, and had bachelor degree. Most of them were private company officers and had
monthly income at 20,001-30,000 Baht. Largely, they made reservations via THAI
offices, traveled in economy class, traveled fewer than once a year and traveled for
vacation. Their overall perception toward THAI service was in the level of “neither good
nor bad”. Their satisfaction toward four service process of departure and arrival service
was in level of “satisfied”. The satisfaction was affected by personal information such as
education and monthly income while it was affected by the passenger behavior such as
class of service, reservations approach, travel frequency, and travel purpose. In
conclusions, education and travel purpose were the variables that highest significantly
influenced the satisfaction.

METHODOLOGY
Research Design
Suvarnabhumi Airport’s international passengers satisfaction research is the
quantitative research by using survey research method to collect data for one-shot
study. And use questionnaire which included close-ended questionnaire and open-
ended questionnaire for research instrumentation. Researcher also set up the
methodology intended for proceed the research.
Population and Sample
The population of research is the international passengers who ever use
services & facilities at Suvarnabhumi airport.
Sample population is the international passengers who ever use services &
facilities at Suvarnabhumi Airport, both of male and female, who age over 18 years old.
Sample population is separated into two sources.
1. International passengers who using Suvarnabhumi airport at the international
departure area on the fourth floor at passenger terminal of Suvarnabhumi airport
2. Non-Thai consumers who ever use Suvarnabhumi airport in term of passenger
in Bangkok
-
18
According to Monthly Air Transportation Statistics of Suvarnabhumi Airport (JAN.
– NOV. 2006), the total number of passengers at Suvarnabhumi airport is 28,274,022
passengers. Therefore, the amount of sampling group is set by using the Yamane’s
formula that permit for error at 0.05 (Yamane, 1973: 583) and the result is 400 samples.
n = N
1 + N (e) 2
n = number of sampling group
N = number of population
e = error that allowed to happen in sampling group which has been set in this
research at 0.05
According to the formula, the amount would be
n = 28,274,022
1 + 28,274,022 (0.05) 2
= 400
So, the number of sampling group equals 400.
For random sampling, researcher employs non-probability sampling by
accessible sampling for selecting the sample.

From table 25, about the passengers satisfaction level in service quality, this
study used the expectancy disconfirmation theory which developed by Oliver, 1980 to
learn the customer satisfaction level by comparing customer expectation and perception.
According to this theory, satisfaction is caused by confirmation or positive
disconfirmation of customer expectations, and dissatisfaction is caused by negative
disconfirmation of consumer expectations. The satisfaction level of each service
dimension will be summarized according to this theory as follows:
For Reliability, the overall expectation was in very good level while the overall
perception was in good level. Thus the satisfaction in reliability results in negative
disconfirmation.
For Tangibles, the overall expectation was in very good level while the overall
perception was in very good level. Thus the satisfaction in reliability results in
confirmation.
For Responsiveness, the overall expectation was in good level while the overall
perception was in good level. Thus the satisfaction in reliability results in confirmation.
For Assurance, the overall expectation was in very good level while the overall
perception was in good level. Thus the satisfaction in reliability results in negative
disconfirmation.
For Empathy, the overall expectation was in good level while the overall
perception was in good level. Thus the satisfaction in reliability results in confirmation.
And the overall international passengers expectation was in very good level
while overall international passengers’ perception was in good level. Therefore, the
-
52
overall international passengers satisfaction level was negative disconfirmation which
means passengers were dissatisfied in service quality of Suvarnabhumi Airport.
Part 5: The passengers’ suggestions for development

Part 6: Discussion
From the study of Lerluck (2005) which is studied the satisfaction of Domestic
Airline Passengers Toward Service Quality of Thai Airways International Public
Company Limited. With the differences of study, the satisfaction of THAI passengers
and Suvarnabhumi Airport’s international passengers was different and similar in
conclusion.
The satisfaction level of THAI passengers were at “Satisfied” level in both of
toward four service processes of departure and arrival service (reservation and ticketing
service, check-in service, in flight service, and after flight service) and service
dimensions (reliability, tangibles, responsiveness, assurance and empathy).In contrast,
this study which is only measured the same service dimensions (reliability, tangibles,
responsiveness, assurance and empathy) that resulted at “Dissatisfaction” level in
service quality of Suvarnabhumi Airport.
About the satisfaction level classified by personal information, THAI passengers
with differences of education and monthly income independent variables were satisfied
differently. While this study had more factors that have a significant effect to
international passengers satisfaction on their expectation and perception in service
quality (age, nationality, marital status, education, income, and experience)

For the satisfaction level classified by passenger behavior, THAI passengers
with differences of class of service, reservations approach, travel frequency, and travel
purpose were satisfied differently. In this study, had only experience factor (included in
personal information) that was the independent variable significantly influenced the
satisfaction of Suvarnabhumi Airport’s international passengers.

CHAPTER 5
CONCLUSIONS
Conclusions
Suvarnabhumi Airport is the new international airport that has been planned to
be the aviation hub of Southeast Asia which provides the international airport standard
in services and facilities for the global passenger. Generally, service sector can satisfy
the customer by offering high service quality and efficient facilities. For the enormous
service provider like an airport has to concern more about the variance of passengers’
needs and wants. Moreover, the significant thing is how to satisfy them through the
service quality with limited resources.
The objectives of the study were to Study the factors that have an effect to
international passengers satisfaction on their expectation and perception in service
quality of Suvarnabhumi Airport and find out the overall Suvarnabhumi Airport’s
international passengers satisfaction level in service quality by comparing passengers
expectation and perception that effected on their satisfaction.
This research is a survey research and collected the data from primary data
which was based on the questionnaire. The questionnaire contented of two parts;
passenger’s personal data and passenger’s expectation level and perception level in
service quality. The 400 sampled population of the total population (28,274,022
passengers) are the international passengers who ever use services & facilities at

Suvarnabhumi Airport, both of male and female, who age over 18 years old. The survey
research was conducted on April 9-17, 2007.
The results of the passenger’s personal data illustrated that 342 international
passengers were 201 male and 141 female. Most of passengers aged between 18-29
years old with non - Asian nationality. Most of them were single, had an education level
at bachelor’s degree. Mainly Passengers had total annual income for the previous year
between USD25,000 – USD49,999 and also used Suvarnabhumi Airport since it opens
for 1-5 visits.
The results of testing hypothesis 1 & 8 illustrated that gender factor doesn’t
have any significant effect to passenger satisfaction on their expectation and perception.
The results of testing hypothesis 2 & 9 indicated that age factor has a
significant effect to passenger satisfaction on their expectation and perception.
The results of testing hypothesis 3 & 10 showed that nationality factor has a
