Commercial Airline Protocol during Covid-19 Pandemic: An Experience of Thai Airways International

Abstract

Introduction: Coronavirus disease 2019 (COVID-19) pandemic has affected the aviation industry. Existing protocols have relied on scientifically questionable evidence and might not lead to the optimal balance between public health safety and airlines' financial viability. Objective: To explore the implementation feasibility of Thai Airways International protocol from the perspectives of passengers and aircrews. Design: An online questionnaire survey of passengers and an in-depth interview with aircrews. Setting: Two randomly selected repatriation flights operated by Thai Airways International using Boeing 777 aircraft (TG476 from Sydney and TG492 from Auckland to Bangkok) Participants: 377 Thai passengers and 35 aircrews. Results: The mean age of passengers was 28.14 (95%CI 26.72 to 29.55) years old; 57.03% were female. TG492 passengers were mostly students and significantly younger than that of TG476 (p<0.0001) with comparable flying experience (p=0.1192). The average body temperature was 36.52 (95%CI 36.48 to 36.55) degrees Celsius. Passengers estimated average physical distances of 1.59 (95%CI 1.48 to 1.70), 1.41 (95%CI 1.29 to 1.53), and 1.26 (95%CI 1.12 to 1.41) meters at check-in, boarding, and in-flight, respectively. Passengers were checked for body temperature during the flight 1.97 (95%CI 1.77 to 2.18) times on average which is significantly more frequent in longer than shorter flight (p<0.0001). Passengers moved around or went to the toilet during the flight 2.00 (95%CI 1.63 to 2.37) and 2.08 (95%CI 1.73 to 2.43) times which are significantly more frequent in longer than shorter flight (p=0.0186 and 0.0049, respectively). The aircrews were satisfied with the protocol and provided several practical suggestions. Conclusion: The protocol was well received by the passengers and aircrews of the repatriation flights with some suggestions for improvement.
