Passengers need to check in big baggage instead of bringing on the plane. That cause inconvenience for everyone. Otherwise flight was good.

The food was terrible especially for a 15 hour international flight. The crew was unpleasant as well.
O
8.0 Very good
Really low quality food especially for an international flight. The crew also was surprisingly unpleasant except couple of ladies. I know we were not in first class but that’s no reason to treat customers as less.

Short flight, no food service
