How mobile-friendly is Jet2?
Jet2 provides an iOS app that is compatible with iPhone, iPod, and iPad.
For Jet2 myJet2 members, you'll be able to manage your account from the app, though using their website will no doubt provide more functionality
The Android apps from Jet2 work with all Android phones and tablets from various manufacturers (Samsung, LG, Google, etc.), and Android Wear watches might also be compatible. You can get the same stuff done on the Android app as you can on the iOS app for Jet2.
Instead of downloading the mobile app, you can try visiting the mobile website of Jet2 to find flights and manage reservations. Click here for their website.
