I will not fly to ICN and transfer to Hawaiian again. Both Asiana and KAL are good flights to ICN. And their lounges are both good. But if flying onward, stay with Asiana or KAL connections. ICN doesn’t do terminal connections well.

Reasonable fair, good service, in sum, I am very happy!

Courteous crew and effective service on-board. Good leg room. Areas for improvement: 1. Limited menu meal menu options. During checking there was no means provided to select meal option. On our return flight the first meal had Pork and Beef options only. Fortunately the second meal had Chicken as an option. Otherwise we would have gone without meal through 13+ hrs of journey, 2. Limited choice and very limited number of movies and TV shows.

I booked this airline twice. The first time, they cancelled the flight due to destination weather condition but without offering any optional flight but only a cancelation notice sent via SMS. I had no choice but to re-book United airline with the same travel date and destination. (no impact on the weather condition Air Premia claimed) The second time, my husband missed the flight due to local traffic in Seoul. Normally, all major airline would helped you to re-book the same flight next day with changing fee only. But Air Premia offered nothing and only requested my husband to re-book a full price ticket.

Don't splurge for the Premium Wide Economy. They compare it to business class. This is not business class, and the seats are very uncomfortable.

For the second meal, the different food choices ran out both times so we were only offered one.

Seating was good in the economy with plenty of leg room. The seat cushions were a little firm though, especially for such a long flight. All meals were Korean as would be expected. The food was typical airline quality. Edible, but not something you would recommend to friends. Inflight entertainment was also all Korean but Korean tv and movies are made well and you can find something to watch. Just be prepared to read subtitles. Overall it was a good flight, especially for the price.

The crews were friendly, professional and courteous. Checking in was easy and smooth. The best part is, as we all know, the price.

The person in front of me was rude. He may came from some communism countries and don’t care of other people. No common manner and sense between human being.

Very nice staff, airplanes, and an excellent value in premium economy.

Food quality is poor. Flight attendants are very friendly and professional.

Gate and boarding processes were handled smoothly and efficiently. Both (connecting) flights departed and arrived on time. The cabin crew seemed anxious and a bit stressed/rushed. Food service was OK, but the hot food dishes were poor quality.

HAVING ANNOUNCEMENTS FOR PEOPLE TO BOARD ACCORDING TO GROUP IS ESSENTIAL N ENSURING N CUTTING OF QUEUES, EXCEPT FOR PRIORITY CLASS PASSENGERS ON A SEPARATE Q

We still get drinks and a snack. Love the gift bags too.

business class is old but still done very well by the team.

Excellent airline. The plane was clean and the staff were very attentive

Good experience although the boarding gate is at the terminal extension hence need to leave lounge to head over earlier.

Thai Royal First is very good. Easy check in , Private room in the first class lounge and escort from ticketing to the plane. Once on board crew was very polite, food was outstanding, and the ride was smooth as silk. Restrooms were especially clean. Great Experience

I'm not interested in improving the airline. Therefore, I won't explain this in more detail. Next time I'll try a different one.

The flight (boarding) was delayed by 40-50 minutes and there was very crowed. They need to improve on the timeliness & boarding process. (They asked passenger to board in groups, but the 2nd group was standing there waiting for 20 minutes!). However, services from the crew was very good, also the food was good as well. I also found the legroom was quite comfortable.

Need to improve on punctuality. My flight was delayed by 1 hour.

I don't like this airline. The website is not user friendly. I tried to check in multiple times and no joy. Then I googled why might this airline not let me check in and it said if you are checking baggage you can't check in. I really thought that I had purchased baggage. Because I have been traveling for 3 months and making sure that I pay for baggage on every flight. This flight they said that I had not purchased baggage but there is really no way to check on the passenger side.

I wasn't able to check in. The website could find my reservation but then an error occurred. I tried 4 times spread out through the day and got the error message every time.

Delayed and very little leg space, my knees were into the chair Infront, when I put one leg into aisle out was overrun by staff.

A truly unpleasant experience with Vietjet. The check-in especially was unacceptable. Our purchased ticket stipulated that our paid-for baggage included one checked bag (20kg), a carry-on (7kg), and a personal item that must fit under the seat. The check-in team insisted that the 7kg limit also included the personal item, which was not mentioned on our ticket. They would not listen to any reason, including that we had planned our trip around these weight limits. We were forced to purchase expensive overage baggage as a result. Throughout, the staff at Denpasar Airport was extremely rude and threatening in their behavior. When we boarded the plane, Vietjet's service did not improve. The lavatory didn't have soap at the very beginning of the flight and this wasn't fixed. We were also made to board a full hour before take-off, only to sit for no reason on the tarmac before a long flight. I wouldn't fly with Vietjet again.

well it was a short flight so there was no food but couldnt answer that question with a N/A There was no entertainment so N/A but the flight was great and staff was number #1

Never on time when I fly and Thai Vietjet App is too complicated. I had booked und paid for seat number 15A but when checked in, I got another seat number and row. I paid extra 50 bath for what??? They couldn’t change and I got no refund. No time to discuss with the ground crew to change it. I would never pay for seat anymore.

Excellent experience nothing could be improved with staff. Was hoping someday the airline will use tape recorded lfor languages that are not common to staff. Probably with AI it might be a good addition

Need more where chair assistant helper I request, but no one help me.

We were packed in like sardines. They did not even serve water on the flight!

Everything was good just the part on the need to transfer via bus to plane

The flight on the 8.10was canceld so i had to by tickt on anather airline As the low say i will need a full refand of the mony i paid you for this flight! Thenk you Dan richental

No snacks meal or drinks for 9hr flight, no entertainment options. Crew appeared tired, irritable. It's apparently a budget airline, they make sure it feels that way.

Un peu déçu par le vol, c’est la première fois que je prend un vol de 6h ou les boissons et la nourriture sont payantes et pas inclus dans le vol. Peut être que c’est propre à la compagnie mais ça m’a surprise. Le fait qu’il n’y est pas d’écran pour pouvoir passer le temps était aussi un point négatif. Cependant le personnel était très agréable.

First time of flying with Air Asia and great choice

Don't even offer water on a 5 and half hours flight. Its laughable one have to rent a blanket.

No free water. Water cost money in a currency that I didn’t have.

Pay for food on an almost 6 hour flight. Very tight space, I had to show my boarding pass for the food I paid and the blanket set. I had an online boarding pass, that didn’t work, I had to take out the printed boarding pass out of the overhead locker whilst my neighbour was eating, as I was sitting in a Center seat. The staff was very friendly and got my bag out but it didn’t make sense. As the online boarding pass was enough for the blanket set. But not for the food. Just to make a check on the piece of paper. I had a warm free meal on an one hour flight from BKK to Samui with Bangkok airways. So airasia just tries to save money where they can.
