You have to prepare for the waiting time for immigration to Vietnam, it takes 3 hrs to go thru and it is easy to get mad of it
TomFlew with Asiana AirlinesICN-CGKJul 2024
We spent our long layover in the transit hotel in terminal 1 of Incheon Airport. The room was small, but was also very clean and well kept. I'd highly recommend this hotel if you have a long layover. The price wasn't bad at all.

The beefsteak on the lunch menu was excellent! I usually do not eat airplane food. I loved it.

The beefsteak on the lunch menu was excellent! I usually do not eat airplane food. I loved it.

Flight was too cold. I wore a regular cotton tee and it wasn’t enough. It was a night time flight so I would have thought a blanket would be provided to passengers. A 4 hour flight and no options for a meal? I flew Asiana the next day from Seoul to Manilla. Same duration, 4 hours. They give everyone a pillow and blanket and serve a meal. Why is United so cheap and holding back meals and amenities? Also, they promote too much gay stuff and DEI in their advertisements. Please be mindful of other beliefs and don’t shove your gay ideology down my throat.

Staff always with a smile and very helpful with my mom who has mobility issues.

It was all perfect and very pleasant for such long flights

The seats felt very small. We were supplied with pillows and blankets, which was nice. Lots of noise from the bathroom, plus exterior noise. Made it hard to hear the entertainment system, even using my own noise-cancelling headphones. The food was really bad. I generally request a vegetarian meal and one was supplied, but the pasta was cold and hard and there was nothing pleasant about it. Two meals were served on this flight; one was a repeat of the meal I had had on the flight immediately preceding this one, which was bad enough I didn't even try it. Drinks were very limited. All I wanted was water, and on a 10.5 hour flight, I was given 3 cups of about 3 ounces each.

We took business class, It was comfortable and I was able to sleep.

Everything was perfect. A flight attendant even brought me snacks after I declined food due to my desire to force myself to follow the destination time zone.

For the most part, it was an enjoyable experience. It's the 2nd half of the journey was a bit uncomfortable. It was on a noticable smaller plane compared to the previous one.

Only process that my luggage didn’t make it to my destination because of short connection but I understand

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."

Purchased exit row window seat for extra leg room and sleep. Worth the price. Attendants maintained restrooms regularly. No snacks/chips/nuts/cookies beyond what was served with meals.

Terrible check in and food was like from fast food

I thought the meals and meal choices were excellent. The cabin staff was helpful and as is the norm for Pinays, extraordinarily empathetic.

Not so good, my business seat is not working properly

Nice new lay-flat seats in Business Class!! What a wonderful experience!

Well it's strange everytime going the flight is late coming back the service is superior

There was something that did not work on every fligjt. No water in business class washroom and inflight entertainment system did not work in business class.

Flight left and arrived on time. Preloading area in Manila could use some help. Area needs to be bigger to at least seat the passengers while waiting. Crew is great nonstop to MNL is a game changer.

Everything was great, except for the inflight entertainment, which wouldn't work on my Samsung Zflip. The flight was smooth despite the heavy rains exiting Tokyo. The cabin crew were very attentive and friendly. I had the pork katsudon, which was very tender and flavorful.

Expensive and yet uncomfortable. Was told by the crew to get back to us for the breakfast meal but never returned, my child was hungry

I had excellent experienced flying with Cebu Pacific on my domestic flight. However, no food and beverage serve might be due to short travel time of 40 minutes.

No entertainment and not expected. Cabin was very cold which brought the comfort score down

Your check in lines were terrible everything else was great!

flight cancelled.. booked through orbitz, yet orbitz won't handle refunds.. never use them again..

It arrived 18 minutes early. Attendant are good. For baording , they should improve especially carrying thru bus.

Super delayed. Delayed to get the bus, delayed to get off the bus, delayed to take off.

exceptionally good with the particular flight because no delay. hope that happens for every flight

Boarding had us in a tunnel with no AC for 15 minutes. Not planned well. And you have to pay for water, get at airport

Kind of worried due to typhoon but yeah we can't do about nature thing. So okay naman kudos to all crews and pilots for the safe landing.

it was good experience though we wait for a minutes in the railday due to no available parking. Keep it up all..

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.
