Clean modern comfortable. Food could have been better, I only ate breakfast I wish they wouldn’t wake sleeping passengers who would rather sleep through dinner. No tea or coffee for breakfast

Clean modern comfortable. Food could have been better, I only ate breakfast I wish they wouldn’t wake sleeping passengers who would rather sleep through dinner. No tea or coffee for breakfast

The flight crew was phenominal! We couldn't have asked for any better. They were experienced professionals.

Crew and service was excellent, but passengers should be offered a welcome drink before take off which did not happen. Food was very good. Unfortunately the lie-flat bed in business class was one of the most uncomfortable I have experienced. The configuration forces you to sleep with your legs at an angle instead of in a straight line, plus there is very little padding on the bed so it wasn't possible to sleep for more than 2-3 hours on an 18 hour flight. For what the airlines charges for a business class ticket their hard product leaves a lot to be desired.

Awesome! Was impressed with the hospitality and the thoughtful services. The cabin attendants were superb.

Crews were great but food not much selection just all tailored for Asian passengers.

The Premium economy class is not the same as some other airlines because there are no economy seats on these planes. Basically you’re getting an economy seat that’s a little wider. The seats are not that much more comfortable. The service and food experience is similar to economy class on other Asian airlines. There aren’t enough toilets for the entire plane therefore we are forced to share the business class toilets that are closed off with curtains.

It was a great flight Food was great Crew was spectacular

In general good, but the machine seems to be long in operation and some functions were restricted as e. g. Adjusting of seats.

The meals were ok,but we weren't given any beverages with the food, only after everyone was served food, maybe short staffed but that's not proper

The flight was close to on time. My suitcase was not loaded in Bangkok and was delivered 24 hours later.
