Abstract

Purpose: The purpose is to investigate the types of communication between aviation industry workers and passengers according to environmental changes following the COVID-19 pandemic. This study analyzes the impact of verbal and non-verbal communication styles of airport staff, especially those working at airline check-in counters, on passenger satisfaction. Research Design: The research design focuses on the impact of verbal communication styles and non-verbal communication factors of airline check-in counter staff, who represent the initial point of contact with passengers among airport staff, on passenger satisfaction. The survey period for sample collection was from July 1 to July 30, 2023, and the study was conducted targeting passengers boarding aircraft through Incheon Airport and Gimpo Airport. Result: First, it is important for airport staff to recognize all passengers, especially corporate customers, as corporate customers rather than simply as individuals boarding an airplane. Second, as the importance of non-verbal expressions increases due to the impact of COVID-19, physical and verbal responses are necessary. Third, it is important to check which language the passenger understands. Conclusions: Since communication through nonverbal expressions has become more important since COVID-19, airport employees need to recognize the importance of nonverbal communication. This awareness can serve as a foundation for building trust between airport staff and passengers.

1. Introduction

Even after COVID-19 pandemic, Air transport industry still face challenges. According to the United Nations World Tourism Organization, the number of international tourists in 2022 decreased by 72% compared to 2019. In response to the post-COVID-19 environment, airlines have strengthened safety measures, including compliance with protocols such as social distancing, and wearing masks when in contact with passengers and employees. For safety reasons, cabin crew have minimized contact with passengers and limited or suspended in-flight customer service. In airport services, communication between airport staff and passengers, such as kiosks and smart check-in, is gradually expanding from face-to-face methods to non-face-to-face methods. Airports and airlines are providing convenience to passengers in non-verbal ways by incorporating technology into their services to respond to the changing internal and external environment following the pandemic. Despite the growing academic interest in interpersonal communication, existing research has focused on verbal communication, a form of communication, and research on the service communication style of airline and airport workers has also focused on verbal communication. There has been a focus on style (Park & Lee, 2019). This study resolves the limitations of existing research by analyzing the impact of airport workers' verbal and non-verbal forms of communication on passenger satisfaction depending on the changing environment. This study is expected to serve as an opportunity to measure and improve passenger satisfaction according to the language type of airport staff.

2. Theoretical Background

2.1. Verbal and Nonverbal Communication of Employees

Language communication and non-verbal communication are used as methods of transmitting information. The interview between the employees and the passengers is the most basic of the transaction, and the basis of all conversation is communication. Szasz and Hollender (1956) classified human communication into three types, mutual participation, activity-passivity, and guidance-cooperation. Ben (1980) divided communication types into affiliation and control. Affiliation type is a passenger-centered cooperative, empathetic, and friendly can be integrated into cooperative styles, and airport staff centered, controlled, and task oriented can be grouped into controlled styles. Park and Lee (2019) in previous studies, the most used style of communication style used by the airport staff are typically cooperative and controlling. Non-verbal communication as nonverbal stimuli induced by people or the environment with a potential message value in communication situations. The meaning of nonverbal communication as a method expressed by airport staff using time, space, and gestures as symbols, and defined nonverbal communication as anything intentional or unintentional behavior. Kim (2006) investigated the effect of service provision as a nonverbal communication on customer satisfaction and customer behavioral intentions. As a result, the boundary between physical language and customer satisfaction was the highest with 0.316. Next, spatial behavior (0.131) and staff language (0.122). On the other hand, appearance did not have a significant effect on customer satisfaction. Hong (2007) divided the study into encounter type (fast food) and relation type (airport). It was found that nonverbal communications including spatial language and staff language had a positive effect on satisfaction levels. Min (2021) studied the effect of nonverbal communication on customer satisfaction and loyalty in hotels. As a result of the study, it was found that all factors of nonverbal communication had a significant effect on customer satisfaction. Combining the previous studies, nonverbal communication has a significant influence directly or indirectly on customer satisfaction and the attributes of information sources.

2.2. Passenger Satisfaction

John (2010) also defined passenger satisfaction as an attitude determined by whether passenger expectation for airport service was met or not. In a study done on the relationship between passenger satisfaction and repurchase intention Hellier et al. (2003) stated that satisfaction is the overall degree of satisfaction or enjoyment perceived by customers about the service provider's service performance results to meet their needs and expectations. Lim et al. (2012) defined the positive emotional state obtained through the service as satisfaction, overall satisfaction after use, and satisfaction with problem solving. Parasuraman et al. (1985) presented 10 dimensions that consumers use to perceive quality to measure passenger satisfaction with airport service: reliability, responsiveness, skills and capabilities, accessibility, courtesy, airport staff communication, credit, safety, consumer understanding, and appearance. These 10 dimensions were refined and reclassified into 5 dimensions; sequel (comprehensive service quality measurement scale) was developed as a tool to measure customer satisfaction.

3. Research Model and Hypothesis

3.1. Research Model

This study's model is composed of three research concepts: communication types of airline check-in counter staff, who are the first point of contact with passengers among all airport employees, nonverbal communication factors, and passenger satisfaction. Additionally, this research aims to confirm the impact analysis of airport staff's communication types and nonverbal communication factors on passenger satisfaction.

3.2. Research Hypothesis

H1: Passenger centered communication of airport staff will have a positive+ Effect on passenger satisfaction.

H2: Airport staff centered communication will have a negative – Effect on passenger satisfaction.

H3: Physical language of airport staff will have a positive + Effect on passenger satisfaction.

H4: Spatial behavior of airport staff will have a positive + Effect on passenger satisfaction.

3.3. Operational Definition in Measurement and Variables

In this study, the measurement variables from previous studies were used, and the measurement variables that can best measure the concept based on possible previous studies were used. In this study, to identify the factors affecting passenger satisfaction, the questionnaires were composed of three categories related to the airport staff’s communication types and nonverbal communication types, passenger satisfaction, and the questionnaires were measured using a Likert 5-point scale.

3.3.1. Communication Types

The communication type of airport staff consisted of a total of 10 questions by revising and supplementing the 'passenger-centered' and 'airport staff-centered' questions presented in previous studies by Lee and Lee (2016), Lee (2021). Items were scored on a 5-point Likert scale, with 1 point for 'Not at all', 3 points for 'Normal', and 5 points for 'Very much so'.

3.3.2. Nonverbal Communication Elements

The elements of non-verbal communication were body language and spatial behavior, and the contents discussed in previous studies by Park and Lee (2019), and Lee and Cha (2016) were modified and supplemented with a total of 12 items to suit the purpose. of this study. The questions were scored on a 5-point Likert scale, with 1 point for 'Not at all', 3 points for 'Normal', and 5 points for 'Very much so'.

3.3.3. Passenger Satisfaction

The four items of airport staff satisfaction, communication style satisfaction, airport staff attitude, and overall airport staff satisfaction presented in previous studies were modified and supplemented according to the purpose of this study.

The questions were scored on a 5-point Likert scale, with 1 point for 'not at all', 3 points for 'normally', and 5 points for 'very much so'.

4.3.1. Validity and Reliability

In this study, the exploratory factor analysis was performed to increase the efficacy of data analysis and to verify the validity of the composition of the research tool. This is to check the accuracy of the specific concepts and properties measured by the researcher can be reflected in accordance with the purpose of this study through data. Factor extraction was based on a factor of less than 40 for each item, and the factor extraction model performed principal component factor analysis using the orthogonal rotation method to simplify the respondents’ perception. In addition, to simplify the factor structure, factor maximization was performed through the Varimax method among orthogonal rotation methods. To verify the reliability of the questionnaires, Cronbach’s coefficient was calculated to confirm the internal consistency between the items. is an exploratory analysis and reliability of 10 items of communication types of airport staff. As a result, airport staff uses professional expression in the process of talking to me, airport staff are formal and work oriented, 2 items in the questionnaire had low commonalities and did not fit the meaning of this questionnaire, so they were deleted, and 2 sub factors composed of 9 items were extracted. The value of KMO which verifies the suitability of the sample of this factor analysis was 0.885, which was investigated as suitable for variable selection for factor analysis. Bartlett’s sphericity test, which indicates if the factor analysis model is appropriate, was 956.938, and the probability of significance was 0.000. this indicates that the factor analysis model is suitable and common factors exist. At this time, the total variance explanatory power was investigated as 64.612%. As a result of reliability analysis to verify the extracted factors, the factors of passenger-oriented and airport-staff-oriented, were 0.906 and 0.617, indicating internal consistency (Kim & Kang, 2023).

Table.4 is the result of the exploratory factor analysis and reliability analysis for 12 items of nonverbal communications. As a result of the factor analysis “ airport staff uses gestures appropriately to easily explain boarding procedures”, “airport staff kept a reasonable distance from me while working”, “it makes me feel like I am in a hurry, “the airport staff leaves plenty of time to handle my boarding tasks”, the four items in the questionnaire were because they had low commonality and did not fit the meaning of this survey, and were then reduced to a total of 8 items. Two sub factors were extracted, and each factor was defined as factor 1 body language, and factor 2 spatial behavior.

4.3.2. Confirmatory Factor Analysis (CFA)

The confirmatory factor analysis was performed to evaluate the validity of the measurement method of this study. The validity of the measurement model was evaluated as x2/df=2.061, CFI =0.952, Tli=0.943, rmsea=0 (See the Table 7). In general chi square is obtained by dividing the chi square value by degrees of freedom, if it is less than 3, the model is acceptable. If the CFI and TLI are 0.9 or more, the model is judged to be excellent, and if the RMSEA value is less than 0.10, then the model is acceptable. It is judged as a level model, and since all the criteria are met, the factor analysis fit of the measurement model was judged to be acceptable. In table_8, the factor load was statistically significant in the items except for the airport employee centered type, and it can be said that the conceptual validity has been secure.

4. Conclusion

This study investigated the impact of airline staff communication styles and nonverbal communication on passenger satisfaction. The research model consisted of a structural equation with airline staff's communication style and nonverbal communication as independent variables and passenger satisfaction, which is influenced by these variables, as the dependent variable. Assessing a research hypothesis, the frequency and effective reliability of the data were analyzed using IBM SPSS version 26.0. First, exploratory factor analysis and confirmatory factor analysis were conducted to analyze the validity of the measurement tool.

The present author then analyzed the structural relationship between airline staff's communication style, non-verbal communication factors, and passenger satisfaction. For calculation purposes, structural equation path coefficients were calculated, and their significance was verified. Additionally, we conducted a bootstrap study to determine the significance of the indirect effect. As a result of model estimation, among the communication types of airline staff, only 'passenger-centered' and 'body language' had a significant effect on passenger satisfaction. Hypotheses 1 and 3 were accepted as positive influences, but ‘aviation staff focus’ and ‘spatial behavior’ were not significant. Hypotheses 2 and 4 were rejected.

According to the structural equation model results, passenger-centered communication style and non-verbal communication ‘body language’ were found to have a significant impact on passenger satisfaction. As the results show, non-verbal communication has the same importance as verbal communication. From a practical perspective on this study, first, it is important for airport workers to recognize all passengers as customers of the company, that is, the airline, rather than simply as passengers boarding an aircraft. Second, airport workers must listen carefully to all passenger needs and respond physically and verbally. With nonverbal expressions becoming more important due to the impact of COVID-19, airport staff's facial expressions, gaze, and posture can affect passenger satisfaction.

Thirdly, it is necessary to check which language the passenger understands. For example, the first people a passenger meets at the airport are likely to be airline or airport staff, so it is important to emphasize smiles and greetings. Additionally, it is important to use appropriate gaze and explanations when talking to passengers, and it is necessary to respond appropriately to passenger requests. On the other hand, airport staff must be aware of the importance of nonverbal communication, as communication through nonverbal expressions has become more important when passengers wear masks to enhance safety due to COVID-19.

This passenger-centered appropriate communication method can be a measure to reduce the possibility of misunderstanding between airport staff and passengers and can be the basis for creating an airport work environment that can increase trust. However, this study has several limitations. First, because there was a lack of research on non-verbal factors and passenger satisfaction among airport staff's communication types, comparison through empirical research was limited. Second, this study should consider the characteristics and environment of the airport but is limited to only spatial characteristics. Thirdly, this may be a limiting opinion as the contact time between airline staff and passengers is shorter than for flight attendants. However, this study will provide an opportunity to increase passenger satisfaction by improving airport staff's verbal and non-verbal service language for better communication with passengers.
