What you need to know about Malaysia Airlines mobile apps
Like many other airlines, Malaysia Airlines offers an iOS app for all of your Apple devices.
For Malaysia Airlines Enrich 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 Malaysia Airlines work with all Android phones and tablets from various manufacturers (Samsung, LG, Google, etc.), and Android Wear watches might also be compatible. You can get the same stuff done on the Android app as you can on the iOS app for Malaysia Airlines.
