How mobile-friendly is Tigerair?
Like many other airlines, Tigerair offers an iOS app for all of your Apple devices.
Also, if you're a member of Tigerair Stripes, you can manage your profile, view your points balance, and more.
Tigerair has an Android app that works with most Android tablets, phones, and some Android Wear devices. Perhaps standard practice these days, the Android app offers the same functionality as the iOS app from Tigerair.
