Really good food and service. Qatar Airways is again and again provided an exceptional experience.

Very poor No information given to why we turned around.. No one at airport to help

Top, only problem about Weather but not depended Qatar Airways. Anyway staff offered kimbo Refreshments

Same as already mentioned. This was more comforting as I got my aisle seat for my knee.

excellent! movie selection just ok, but everything else was wonderful.

Charged extra amount for the baggage wait. Even it’s less than 23kgs. Those machines are showing wrong weight and they were charging money wantedly from everyone.

The boarding experience did not follow the Zones that were listed on the boarding passes. This was a two-level aircraft with many passengers. Because zones were not called out by the airline staff, there was simply a mob trying to board and it was not a pleasant experience.

It would help id flight crew were not rude and showed some courtesy. They were shouting at passengers and yelling instructions as if we were school children at lunch cafeteria!!

You are the best, keep up the good work. Thank you for allowing me and my family to fly with comfort.i am waiting for upgrade some day. Thanks again

Friendly and discreet staff. Could have done with a few more offers of water/snacks overnight. Movie and tv selection notably poor. Seats not especially comfortable
