How mobile-friendly is Easyjet?
There is an iOS app from Easyjet which will work on your iPhone, iPod, or iPad.
For Easyjet Flight Club members, you'll be able to manage your account from the app, though using their website will no doubt provide more functionality
Easyjet 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 Easyjet.
Instead of downloading the mobile app, you can try visiting the mobile website of Easyjet to find flights and manage reservations. Click here for their website.
