In order to understand whether passengers feel comfortable on the airliners, questionnaire survey was conducted on 34 international airliners and 103 domestic airliners, with 150 effective answers collected. The results show that passengers are satisfied with the overall cabin environment and noise is the main factor that causes dissatisfaction and is closely related to the general satisfaction rates. Passengers are more satisfied with airbus than boeing airliners in terms of thermal comfort, pressure, noise, illumination and air quality. Domestic airliners are much higher rated than international airliners in illumination, air quality and thermal comfort.
