The latest info on Thai Airways mobile apps
Like many other airlines, Thai Airways offers an iOS app for all of your Apple devices.
Royal Orchid Plus members will also be able to use the app to manage their profile, view account activity, and more right from the app.
Thai Airways 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 Thai Airways.
