How mobile-friendly is Air China?

Like many other airlines, Air China offers an iOS app for all of your Apple 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

Air China 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.
