United Airlines

You might think that if United Airlines is the biggest airline operator in the world, it would also have one of the best applications. That is up to the users to decide, but the app itself comes with quite a few options that should make people very happy.
 
Users care about flight information more than anything else, and this is the central part of the application, although it can do a ton of other stuff as well. For example, users will be able to also book their flight straight from the app, to scan your mobile boarding pass directly from the app home screen for quick access, to view details about the current flight status, to manually add trips, and much more.
