How mobile-friendly is Air France?

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

For Air France Flying Blue members, you'll be able to manage your account from the app, though using their website will no doubt provide more functionality

As the most popular mobile platform in the world, Air France has taken notice of Android and provided an app for most Android devices. Perhaps standard practice these days, the Android app offers the same functionality as the iOS app from Air France.
