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

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.

Be prepared for delays and ok service. The planes they fly to Manila are usually older and not as well maintained on the inside.

Airline reviews

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.

I generally request a vegetarian meal and one was supplied, but the pasta was cold and hard and there was nothing pleasant about it. Drinks were very limited. All I wanted was water, and on a 4 hour flight, I was given 2 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

The boarding process was good. The toilet could be better maintained.

This has been the worst experience I've ever had. We arrived to Ho Chi Minh Airport and were supposed to get our Asiana ticket from the transfer counter as we came with a different airline. However, the staff at the transfer counter were not helpful and kept giving us different information. We were first told by Asiana airlines staff we had to wait 2 hours so they could print out and give us our tickets, then someone else told us we had to wait 3hrs, someone told us "I don't know, just go sit and wait and we will tell you later." This was at a place in the Ho Chi Minh airport that had no coffee or food shops, nothing, just immigration (to enter Vietnam with a Vietnam Visa) and security (to transfer into the gates) but we needed our printed boarding pass to go through. It wasn't until we demanded to speak to a supervisor as our flight time was 1hr away because they kept telling us "there's alot of time left for your international flight, we will get your tickets later" we still had to wait around 20minutes for the "Supervisor" to give us our tickets. I would NOT recommend Asiana Airlines, especially if going thru Ho Chi Minh Airport as they are not helpful. (We almost missed our flight, due to their lazyness and incompetence of printing our tickets) I would suggest Asiana Airlines to have a Machine in the transfer area so passengers can easily print out their boarding passes themselves and save some money by not hiring incompetent staff that can't do a simple task such as printing a boarding pass.

Great service. They could offer vegetarian food and do more to reduce waste.

I like the food, the crew and everything.!!! Except for the delay in our flight.

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."

love the flight but the chairs are not comfortable mostly for smaller people

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.

I can't complain. Flying with Philippines airlines was the best choice. They are the best option in the Philippines.

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

Ground and flight crew very courteous and professional. Seats are just ok. Entertainment could be upgraded with newer movies. Food was not good at all.

My finger has been hurt by seat, but no answer from you.

Not much legroom in economy seats and aisle. Bathrooms are not maintained well. Staff can be friendlier. Food is barely edible.

Food was satisfactory, movie monitor not working. Other than that on time and pleasant crew.

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..

I was memorable! THIS FLIGHT WAS ALL ABOUT WAITING! WAITING TO BOARD SINCE FLIGHT WAS DELAYED. WAITING IN THE RUNWAYS NO AVAILABLE PARKING BAY. FOR THE LAST TIME WAITING FOR FOOD COMPENSATION

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.
