How mobile-friendly is JetBlue Airways?

JetBlue Airways provides an iOS app that is compatible with iPhone, iPod, and iPad.

For JetBlue Airways TrueBlue members, you'll be able to manage your account from the app, though using their website will no doubt provide more functionality

JetBlue Airways has an Android app that works with most Android tablets, phones, and some Android Wear devices. Perhaps standard practice these days, the Android app offers the same functionality as the iOS app from JetBlue Airways.
