How mobile-friendly is Sri Lankan Airlines?
There is an iOS app from Sri Lankan Airlines which will work on your iPhone, iPod, or iPad.
For Sri Lankan Airlines FlySmiLes members, you'll be able to manage your account from the app, though using their website will no doubt provide more functionality
Sri Lankan Airlines 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 Sri Lankan Airlines.
If you're just looking for their mobile site, you can head on over to http://www.srilankan.aero on your mobile device.
