Very crowded and the economy seats were the smallest and with the least legroom I have ever experienced. Cabin staff were excellent although the food service was chaotic as they were being each person their food individually instead of from the wagon.

Very crowded and the economy seats were the smallest and with the least legroom I have ever experienced. Cabin staff were excellent although the food service was chaotic as they were being each person their food individually instead of from the wagon.

Everything was very good or excellent, but the seats were extremely uncomfortable and painful.

The crew were efficient. The pilots seemed professional. It was a bit chilly in our seats. The sheet provided weren’t very helpful.

The Boarding process was great. Particularly since my wife and I require assistance. The flight attendants were amazing. We travel frequently; they honestly were a cut above. 😀

Plenty of leg room, temperature was great and staff was excellent. Would do it more often.

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

Great. Very smooth. Plenty of information. However, wish they would give out a menu in advance of making a dinner choice like other international airlines. The flight attendant says chicken or pasta and there are details about ingredients or spices requiring the passenger to ask which requires the flight attendant to answer many times. So easy to solve this problem. P

All fine save for the abominable catering. Really gone downhill. We found it all inedible.

Late flight caused a missed connection, had to be put on a later international flight without my requested vegan meal.

Half the bathrooms assigned to economy were out of action
