Acceptable but amazingly slow

The app itself is acceptable for making bookings and loading boarding passes. However, Ive recently had huge problems with it. Purchases cannot be completed due to some random compiler error thats obviously not handled. The app itself is extremely slow. Especially when choosing dates, the picker stays on the selected date for what feels like 5 minutes. Same goes for e teeing airport codes. All in all the app has potential but it seems like its compiled and run on Windows 95!
