The in-flight sales UI is very well designed and easy to use. The layout is clear, and all menu options are easy to find, which makes ordering items quick and stress-free even for first-time users. The buttons are large and responsive, so passengers can navigate smoothly without confusion. I especially like how the product categories are organized, allowing users to browse food, drinks, and merchandise efficiently. The checkout process is simple and intuitive, reducing waiting time and improving the overall onboard experience. Overall, this UI greatly improves usability and makes in-flight shopping convenient and enjoyable. It is a well-thought-out system that enhances passenger satisfaction.
