Passengers are paying more attention to their comfort during flights. Passengers choice of airline depends on their level of satisfaction and sense of comfort in the aircraft cabin. Many factors of the entire cabin system, including the cabin environment, facilities, services, physiological and psychological variables of passengers, all have an impact on their comfort. Airlines are increasingly focusing on comfort to differentiate themselves by developing the aircraft cabin interior to enhance passenger comfort and obtain a competitive advantage in highly competitive markets. The emergence of smart aircraft cabins has provided smart solutions to all discomfort issues that negatively influenced passenger experience during flight. The smart plane of the future has the potential to smooth cabin operation and improve the customer experience in numerous ways such as smart overhead compartments, futuristic smart seats, smart dimmable windows, smart service, and Zero-Touch entertainment screens with 4k clarity. The aim of the current study is to evaluate passenger satisfaction with the current aircraft cabin interior in EgyptAir and investigate factors that influence passenger discomfort in the aircraft cabin. Furthermore, explore how passengers perceive the "smart cabin" in addressing their discomfort issues as well as its influence on enhancing their comfort during flight. To meet the study goals, an online survey was distributed among Egyptian frequent travelers on EgyptAir. A total of 311 valid surveys were collected and analyzed
