What you need to know about Qantas mobile apps
Qantas provides an iOS app that is compatible with iPhone, iPod, and iPad.
Also, if you're a member of Qantas Qantas Frequent Flyer, you can manage your profile, view your points balance, and more.
The Android apps from Qantas 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 Qantas.
