How mobile-friendly is Monarch Airlines?

There is an iOS app from Monarch Airlines which will work on your iPhone, iPod, or iPad.

Also, if you're a member of Monarch Airlines Vantage Club, you can manage your profile, view your points balance, and more.

Monarch Airlines has an Android app that works with most Android tablets, phones, and some Android Wear devices. As is often the case, the Android app offers the same functionality as the iOS app.
