The latest info on Air China mobile apps
Lucky for you Apple device users out there, Air China has an iOS app that will work on all of your devices.
For Air China Phoenix Miles 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 Air China 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 Air China.
Also take a look at Air China's website by clicking here — you should be able to do what you need there.
