I have no idea why there's so many whining reviews. But high marks for the interface and ability to upload documents to be verified as well as your trip!! Straightforward and easy to use. So downloading the app is pretty useless until all functionality is present. I downloaded it to not use paper documentation! So please note one cannot use the app fully at airports as of 2/23. AA staff are somewhat unaware of how this app will work, especially internationally. Here is what people say about VeriFLY: App would be beneficial when full functionality is rolled out. Well, as a top-performing app with an overall rating of 1.40 from 26 votes cast, I can safely confirm that It's good and worth trying.
