Clunky
One of the hardest airline apps to use. Basically a wrapper for the website. Impossible to change seats after checking in. Weird, unexpected UX like certain functions on front page and others requiring "manage my booking." Need to "exit this booking" to see other bookings. Offers upgrades and then wraps web pages that are hard to scroll around and not designed for mobile. Does not update the departure information for delays in passbook. Signed out of flight and brought up return flight in the midst of a long delay so couldnt check status. Not designed for larger displays like iPhone 6 Plus.
