How mobile-friendly is Ethiopian Airlines?
The Android apps from Ethiopian Airlines work with all Android phones and tablets from various manufacturers (Samsung, LG, Google, etc.), and Android Wear watches might also be compatible. With their Android apps you can search for flights, view existing reservations, or go paperless and use your mobile boarding pass via the app or Android Wallet.
For Ethiopian Airlines ShebaMiles members, you'll be able to manage your account from the app, though using their website will no doubt provide more functionality
