My baggage (1) didn’t arrive with me. I am waiting for it.

Level of cabin service was poor for what i'd expect from Business Class. had to go to galley to ask for beverage or refills. Final outbound service wasn't fully served because service was started late, as a result of the crew taking a break later than planned during flight and having compressed time before landing (no clear how this poor planning was possible on a 10 hour flight). Seat comfort was poor compared to Emerates and Ithiad

This is just for first leg, second leg from London Heathrow to Delhi was the worst.

The seats often do not function - in the premium economy the seat does not lean back. The passenger in front of me decided to come and sit next to me on his own volition because his seat was not leaning back.

The sitting for business class was very poor. It was cramped. Some of the seats were defective and could not be kept perfectly upright. If the passenger in front reclined, the passenger behind was trapped in a narrow space. I would consider other airways in the future.

The flight was very delayed in taking off - which was out of control of the crew, but then the pilot worked hard so we only arrived about 30 minutes late. Everyone was very friendly and accommodating!

Plane is old. Toilet did not work. Once in Singapore the continuation to London was cancelled.

Flight was canceled with little notice or explanation. There were no other flights to Belfast from Heathrow, so I had to travel across town to London City (or wait until the next day).

In the "old" configuration Club class, in an aisle seat you are literally sleeping in the aisle with no privacy at all. In addition, there is hardly any storage space, and it is hard to make sense of the seat controls.

Everything was excellent, although flight delayed however can’t control that, but what I don’t understand is why the smallest portion of food ie: bit of rice & bit of chicken (no exaggeration) no salad, no veges, nothing else, but cake & icecream later…this is just not a great reflection on the quality of airlines. People spend $1,500 on a flight surely airlines can spend an extra $1 on their passengers meals…even bread & butter can do the trick. ESP on a 8 hour flight! Cutting costs is one thing, but this is just not ok.
