The app is okay. I generally prefer Qatar Airways, but the customer service at Doha transfer/hotel bookings is atrocious and employees are very rude. Also the rest "beds" in the rest area of the business lounge are shaped in such a way that it's impossible to sleep. My last flight (19/12) had a 6-hour lay-over in Doha, so I paid almost $100 extra to be able to rest, but it was impossible, so it made for a miserable trip. Please take a look at these issues. Not good for an award-winning airline.
