How mobile-friendly is Aeroflot?

There is an iOS app from Aeroflot which will work on your iPhone, iPod, or iPad.

For Aeroflot Aeroflot Bonus 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 Aeroflot work with all Android phones and tablets from various manufacturers (Samsung, LG, Google, etc.), and Android Wear watches might also be compatible. Perhaps standard practice these days, the Android app offers the same functionality as the iOS app from Aeroflot.

Also take a look at Aeroflot's website by clicking here — you should be able to do what you need there.
