The flight crews were extremely professional helpful and courteous. Departure and arrival times were accurate. No delay. Thanks

Not very comfortable seated in the back plane due to turbulence

Everything about Korean air is great, hands down! Will always prefer this airline from other carriers.

Ford not that great the seat not to big for leg room like other airline

Crew was ok, but some passengers were a bit rude. Again, all outlets were not working, only the really slow charging usb plug on the entertainment system. Entertainment system was also bugged, some features just crash, the touch screen wasn't working and when trying to watch a movie the onscreen display kept flashing off and on making it very difficult to watch.

New plane. Perfect gluten free meal Very flawless procedures from check-in to the landing. Taking off on time and landing even earlier and the luggages are already there after shortest arrival report.

It was ok. Not good and not a bad experience

I like your stewardess, they are nice. However, your food could have been better and wheres your dessert? You do not offer beer or scotch. I do not drink alcohol biut my husband can have one or two, he has to ask if he can have one. during dinner or lunch, it should be offerred. Also, you do not have the most famous drinks ginger ale

Not accommodating ground staff On board slow service Crew members not very friendly

lunch was good; breakfast was kinda meh cabin temprature was way too high new entertainment system but somewhat limited content

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."

Upgrade their seats. They’ve got 20-year-old business class seats in their 777s. The food choices. On the way to Manila and the way back I thought we’re lousy compared to other carriers. The staff was fantastic and very happy.

Continual rescheduling of flights, inflight entertainment system did not work, staff not pleasant to interact with.

everything was excellent the crew the food, crew was extremely friendly but wish there was a tv..📺

We did booked shorter layovers but flights changed and layovers are too long good thing Philippine Airlines give us a hotel in manila but here Vancouver to Calgary too long layovers and there is enough sets to wait closer to air canada and they will open 4am.we were here 1 am .our flights schedule for air canada 8:10am.we paid expensive flights but not happy of lay over Vancouver to Calgary.

Not a pleasant experience from the start of booking first flight all the way through to the actually flight. Only saving grace is the food.

There is a problem with the sound while watching movie or listening to the music ( the sound is static & goes on and off). Aside from the sound, the experience was good & stewardesses are nice.

Everything could better always late always rescheduled flight is worse and costs me a hotel room! The dirtiest planes I’ve ever flown on slowest to board . Just awful will never fly again with them

Not leave 12 hours late. This airline is horrible always late does not refund upgrades for cancelled flights inept counter staff.. needs to be shutdown

My biggest concern was with all the schedule changes. Both inbound and outbound flights times were changed, including a time change less than two days before the scheduled departure.

The charges for overweight luggage were not clear, I think I paid twice, I didn’t argue because I was traveling alone & already felt exhausted.

The flight was delayed by an hour . Traveling with 75 year old father was difficult and then when he asked for water he was asked to purchase :-) . Overall just an ok experience.

Overall service is good, the only thing I would like airasia to improve is there seating. Their seat handles are broken as well as the back rest

Boarding with air asia is excellent via organized lines by zone except when there is only 1 gate agent and no scanner, only by tearing tickets??? Crazy

The flight was supposed to depart at 9:25. It departed at 9:00. Im glad we were early and did not miss it.

They wouldn't even allow us to bring water from the fountain on board the aircraft.

Premium seats should have legroom this one didn't have it. I had 2 free checked bag but I got charged for while it shows on my reservation

Terrible airline! This airline just ruined our family vacation due to a 12 hours delay as a result of their operational issues.

Too many flight delays. Airport terminal serving Boracay needs upgrades.

Over 6 hours delayed.. using philippine air fleet planes are beat up dirty and uncomfortable. Have been flying air asia for over 4 years from Manila to Tokyo and kansai as well as several local flights from Manila to Bacolod and Cebu.. 3 planes were down for maintenance and caused havoc.. need to invest in new fleet or seriously clean and upgrade the existing fleet. Will not be flying anymore until fixed. Several options out there now to choose from as air asia prices have skyrocketed.. no point in using them anymore . Severally upset passenger here. They can’t even manage the queuing of Zones for boarding as it’s a crab fest free for all now. No discipline and let the passengers in line to board just run into any lane possible.. and priority luggage?? Forget it I’ve paid for it for the last 6 flights and never got it first.. air asia has turned into a expensive joke.. use Cebu pacific or zip air now..

We had three flight delays before eventually taking off 3 hours late. Inflight service was very limited, but it was a relatively short flight. Luggage was delivered promptly.

Paid for seats near the window but given seats right at the back, near the toilets. This location was so noisy with the blasts from the aircraft engines blowing beside. Not a nice one 😞.

Flight was delayed 2 hours, which seems regular with this airline. Aircrew were avarage, friendly but robotic. At check in I asked for a spare seat. Got some stupid response about loading capacity (it was 85% full!) Then passengers behind jumped up and moved to vacant exit rows, they obviously didn't pay for. Waited over 20+ minutes to disembark, with ground staff trying to squash all passengers onto 1 bus. Causing even more delays. Unsafe and stupid! But this is a problem at Saigon airport. Overall a very average experience!

In experience we didn't even get water unless it was paid for. Even Bamboo Airlines provided free water. The flight was cold with no blanket being provided. The flight attendants were not responsive in keeping the passengers under control. I complained about fellow passengers playing loud music several times before one of the flight attendants to action. I will not recommend flying with Vietjet unless things improve.

I have few bad reviews about VietJet, but my experience was really good and it worth every penny..

Not even free water. NO legroom. Narrow seats. Not enough room to even hold a book at reading distance in front of you.

No food? No movies? No water?? On an international flight, really???

No water or snacks. Crew did not give us arrival cards. There was no need for more than 1 flight attendant as they did not do anything

I got to the airport and flight was cancelled without notice

Some chair in the flight should be maintained, but I think they may not have time to check every seats, since it is high demand in this period.

Our experience was the worst. Over 2 days flight was changed and delayed 4 times. Not impressed
