How mobile-friendly is Frontier?
Like many other airlines, Frontier offers an iOS app for all of your Apple devices.
EarlyReturns members will also be able to use the app to manage their profile, view account activity, and more right from the app.
Frontier has an Android app that works with most Android tablets, phones, and some Android Wear devices. You can get the same stuff done on the Android app as you can on the iOS app for Frontier.
