How mobile-friendly is Wizz Air?
Wizz Air provides an iOS app that is compatible with iPhone, iPod, and iPad.
For Wizz Air Privilege Pass 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, Wizz Air has taken notice of Android and provided an app for most Android devices. You can get the same stuff done on the Android app as you can on the iOS app for Wizz Air.
