Not yet available for public download, German low-cost carrier Germanwings, which has just recently overtaken most of Lufthansa's inner German and European flights (not departing/arriving in Frankfurt or Munich), has just announced that its Android app - launched back in July - should support English soon. The initial release only supported German, which doesn't make any sense for an airline, especially not if its Lufthansa's daughter-airline. However, according to Germanwings' English website, the new app version will also come with enhanced features. While the mentioned link to Passbook is most likely for the iOS version only, info on your upcoming flight and flights you're following will be shown on your personalized homepage.
Furthermore it's said that the new version makes navigation easier for check-in, boarding pass access, flight status as well as flight booking and much more. Whether booking flights or extra services, the new version is said to make it easier to plan and book on the go.
UPDATE: Ok, it took Germanwings "a little bit longer", not to say over a month, but the German low cost airline has finally released its updated Android app which is now also supporting English. Definitely good news for international travelers which have to take Germanwings, instead of Lufthansa; after Germany's number one airline has handed-over many of its German and European connections.
