I like the landing which is nice and safe, seats are also comfortable

Staff on board were good - food was fine tasted good - tv was old 1970ts in seat back but hey it was a 2 out flight so no drama

Korean Air is unlike any other major airline I have flown with. The grace and respect that the staff has from check in to de-boarding is unmatched. The flight attendants this time were especially wonderful to my five little children. They helped us rearrange to more suitable seating, brought our children’s meals, and patiently waited for them in the aisles when they had to use the bathroom. We felt so welcome and comfortable. I really appreciate the meal voucher when our flight was delayed. I am grateful to have had such an stress-free experience.

It's good overall. Flight was packed. Inflight entertainment choices were lacking.

They were very accommodating of a dietary issue. Nice movie & tv selections. Non-stop helped get through a very long (15 hr) flight

They did an excellent job helping me with a wheelchair. I couldn’t have asked for any better help.

The delay in Korea was a pain and set us back a day. I have to give big props to Korean Air for setting up a hotel with dinner and transportation to and from the hotel. I also needed assistance with a wheelchair and they did an outstanding job.

The boarding process for Korean airlines is very straightforward and easy. You've never met such helpful and friendly people. The food was great and the entertainment options were excellent too. My teenage boys found programs they wanted to watch while I had fun watching a full season of the Last Man - the Blind Investigator (Japanese), which my wife enjoyed too. My only complaint was that it takes a very long time to taxi at ICN (20 minutes) and the pilot had to hold at the gate for 10 minutes after our scheduled departure time, which meant we got to Seattle 27 minutes late. Luckily I had a long enough connection to make my next flight, but just barely.

Best service I’ve ever had Flight attendants are nicely dressed and look very professional

My second flight wasn't better than the first one. And this is 14 hours trip, crew came out only to offer food and the choices was poor. This food choices are good for Asian people but not for westerners. The breakfast kind thing was a corn sausage really disgusting. The air-conditioned blower really blow high and cold, turn out on my arrival to feel seek, that makes the trip uncomfortable. The crew didn't not really come out during the trip to offer drinks or snacks. No fruits available. Very poor service

I loved everything, I was just a little confused on my bag allowance. When I checked in it said I was allowed 2 check in bags, but when I got there they said I was only allowed 1 so I had to pay an additional 200 dollars! Other then that everything was great! I would love to use your Airlines again when I fly out to Manila again in late May, however I want to be able to have 2 bags included this time lol 😆

the water for tea could have been hot, entertainment was awful, lots of old movies and TV shows

They used Thai Smile plane, which is a smaller model and used to service only domestic flights; hence, the plane is small and quite compact. No entertainment on the flight. While boarding was delayed, it was done in a quick manner.

I give EVA 5 stars in every category. I enjoy this airline and it's great team of employees. I always highly recommend EVA to friends and family and everyone.

The flight was delayed going out of the gate at BKK that made it a difficult challenge to get through immigration transfer at tapei and make it to my departure on time. This appears to be a recurring issue. The flight crew and cabin crew were excellent. The food was very nice.

The boarding efficiency was good. A couple of the flight attendants did not seem in the best of moods. Overall it was a good experience.

The setting configuration of the aircraft stinks. Nobody should pay business class fares and be so uncomfortable. The design of facing fellow passengers is a brilliant nincompoop.

Entertainment is limited with a relatively old catalogue. Wi-Fi never works and the cabin and lavatory had evidence of a lot of scuff marks and temporary repairs. Nothing unsafe, but a bit tatty in places.

Delayed flight in Singapore caused the transfer at Bangkok to be very stressful. Fortunately, no elderly were in this trip, else it will not be possible to catch the connecting flight. There were also several occasions throughout the flight journey where some of the passengers were not wearing their seat belts despite several remainders from the stewardess.

USB charging port was not working at my seat 48K.

I enjoy flying with Thai Airways, however their B788 business class configuration is quite dated. Additionally , while the service is always friendly and efficient, I’m getting tired of the same “usual suspects” when it comes to food choices. Since it was a lunchtime flight, what about some gourmet sandwiches or some type of salad dish for the main course? The entertainment options are also quite limited and this is not unique to TG, so much so that given the short duration of the flight I ended up not bothering with any entertainment. Finally, despite signs around the cabin advising wifi available, I was unable to con-net and in fact I’ve never been able to connect on any TG flight over the last year or so - what’s the go here??

Always liked Thai Airways but in the past they have been very expensive, not being a millionaire just yet, I will use cheaper airlines. Bangkok to London £370 11 hours 45 mins. Old plane but ok. Lovely ladies on board, very polite. Food was ok. Will always use them if the price is right.

At the boarding gate, Jeju airline accepted "carry on" bags for checking in for free due to the "limited cabin space". This is because most passengers were carrying multiple bags that exceed the size and weight limit for carry on items. Rather than inspecting carry-on bags at the counter and requiring excess bags to be checked in for a fee, they allowed freeloading at the boarding gate to to the detriment of those who paid the fee for checked bags. This is totally unfair.

As posred earlier the crew was very accommodating & professional. Thank You Allen

All though you can not help it the kids was loud and unruly, The crew was very accommodating and professional. Thank You Allen.

No priority counter check in for families with young children.

The flight was delayed from GUM to ICN, there was no notification on how delayed the flight would be. Although we received notice, there was no specified time given. The flight was also very uncomfortable.

Cons: "Sold me a ticket then cancelled 15 minutes later due to not having updated information from the airline on bookings."

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.

Pros: "The flight got me to where I was going."
Cons: "If you are.looking for some entertainment for a long flight, there will not be any."
