The latest info on Alitalia mobile apps
The iOS apps from Alitalia will work with all of your Apple devices, from iPad to iPhone
For Alitalia MilleMiglia 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 Alitalia 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 Alitalia.
