I have done this prototype for mobile on Figma, it is the mobile version of the desktop website (Project 11 Prototype for desktop). It is a medium fidelity prototype and shows the best user flow when booking a flight on line but for this prototype it goes from the home screen up to the seats.
It is based on research I have made on different mobile apps for airlines along with some user researches such as online surveys and usability testings. I used the best features possible so that the user can book his or her flight fast and easy.
Here is the link so you can test the prototype for yourself , I have also made a video showing the interaction.
When testing the prototype you need to click on the sections that are highlighted in red.
