Food is horrible. Flight was good and the staff were mostly men.

Delayed suitcase - terrible service to get my suitcase next day, I was informed it would arrive today in the afternoon (Jun/28). Now, I was informed I may or may not receive it until 3 am (Jun/29).

Seats were comfortable, but boarding was the worst I've ever seen. Way too much walking to get onboard as we had to go up & down steps several & then bus took us halfway around the airport for boarding & had to board outside after a very long bus rood.

I will never want to book with these people. They are arrogant and rude. Food was really really bad, crew was even worst

The plane was so old, it needs to be retired! The windows were rattling we paid for premier economy and there was no footrest. Video console was so old, barely had any games for kids. Video console is very slow to react. The gaming console was broken. The foldable food table was sticky and the air hostess had a rough time opening it and closing it for us!!

Generally very good. I think their service is better than some other big names I used to travel with. Their food variety is second to none - and you can place order beforehand. Their seating design is a bit awkward for service, I'd say. Flight attendants must be tall enough - long legs and arms - to reach the window seat passenger while crossing over the isle passenger. Also appreciated the variety on entertainment.

Could have used more leg room for “business class” which is basically coach with a middle seat blocked. Crew was friendly, attentive. Zero entertainment.

Generally okay. Disappointing compared to some of their competitors. My seat hadn’t been cleaned properly which was upsetting

Seats not as comfortable as I had hoped. Food was very nice, service was fine. Entertainment options very nice. Had thought the premium economy was a more plus 2-3-2 layout but it was a 2-4-2 with seats not as wide as I had expected.

It’s the old style plane with the old Ying Yang seats doesn’t compare to other airlines with newer planes.
