This study examines passenger adoption of self-service check-in kiosks based on the technology acceptance model (TAM) and its extension. This study investigated the relationships between three independent variables (technology self-efficacy, need for human interaction, and perceived enjoyment) and two TAM's cognitive variables (perceived usefulness and ease of use). The analysis of these relationships is novel in aviation self-service technology research. Structural equation modeling (SEM) was employed to analyze 346 valid responses. The analysis reveals that enjoyment enhances the perception of self-service check-in kiosks as useful and easy to use, resulting in greater intention to use them. Moreover, passengers with higher confidence in their technological self-efficacy are more likely to perceive check-in kiosks as helpful. However, passengers may perceive kiosks as less useful when they require more human interaction. The results of this study contribute to the current knowledge on aviation self-service adoption. Additionally, managerial implications are offered to improve the future of airlines' passenger services.

Objective – This article aims to preliminarily examine and summarize the impact of COVID-19 on airline business and to briefly investigate how the airlines respond. Methodology/Technique – The researchers synthesize data and information collected from industry organizations' reports and related academic literature. A traditional narrative literature review was implemented to examine and summarize the impacts of COVID-19 on the airline business. Findings – The results show that COVID-19 has operational, market, and financial impacts on airline business. In response to the COVID-19 situation, the airlines have updated their operational procedures and searched for alternative revenue streams. The authors also provide suggestions for future research. Novelty – COVID-19 is an emerging infectious disease. Very few scholars have conducted studies on the impacts of COVID-19 on airline business. This article contributes to the academic literature by categorizing the impacts of COVID-19 on airline business. Future studies can further investigate the impacts of COVID-19 on airline business using this article as a starting point. Type of Paper: Review. JEL Classification: M10, R41.
