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.

Smooth sailing trip, pilots are good. Less amount of food offered but the quality is okey.

Kayak uses scammer sites to steal money from their victims.

When one asks for water because they are dehydrated, bring more then a sip or two in a small cup. Bring them a whole bottle.

Food could be better it was okay. Entertainment seems dated it was something but in this day and age could be a lot better.

Very clean ,flight attendants very professional,nice , Boarding was very easy

The aircraft was massive (A-380) and became crowded with 400+ passengers on board.

Coming back to America was a peaceful flight everyone and everything was perfect

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.

Tightest knee space ever experienced on any budget airline. Crew polite and efficient, take off and arrival on time. Surprised that they did not offer water on flight except as sales product. Questions about Food and entertainment not applicable since neither are offered.

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.

Flight was really good, considering the semi bad weather in MNL. Food was great. Crew kept offering throughout the flight. Wifi signal was intermittent though.

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.

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

Flight was delayed and caused us to miss our connection. American Airlines did nothing to compensate us and they lost 2 out of 4 of our checked baggage. They have not returned inquiries into customer service and have not offered us compensation. Terrible.

First and foremost it was a Philippine Airlines.my experiences ,number one non- stop flight no lay over not other airlines,number two ,boarding they calling by ground letter.number 3 stay on time no delay flight

When I checked in, there was no option available for selecting a gluten-free meal. The lounge offerings were inadequate for someone with a gluten-free diet, and the staff in the lounge were not helpful at all.

Biz class is way below what other airlines offer. The food was mediocre at best. A WiFi was intermittent and movies were dated. Honestly the best part of the trip was that the Mabuhay lounge in SFO was closed and they gave us pass to Air France lounge. My advise, fill up there before boarding plane.

Checking in was okay but boarding a little bit slow

Upgraded to a business class by an auction and it was the cheapest bid.

We were told at check in that my wife and I will be sitting together. We were not. Our mistake was we did not check our seat assignments on the boarding pass until we got on board. At that time there was no solution because the flight was fully booked.

The staff were excellent, the seat comfort is very poor on a three hour flight, Scoot Airline seats were poor quality also, they are okay for a short flight time of no more than one hour!

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

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.

"usual delay" for an hour.. they are usually missing punctuality.

better handling of the checked in luggage. they destroyed mine

the process of paying for the excess baggage weight, the check in process and the boarding process are subhuman. this is an airline devoid of customer service

Flight was 2 hours delayed. No explanation provided. Gates changes twice.

Waited Over 5 Hours for a 1 1/2 hour Flight. Manila AirPort is absolutely pathetic. This was after Cebu Pacific personnel tried to overcharge me for excess baggage.

I am 74 hrs old and I appreciate walking on the ramp instead of using the stairs. Too bad they didn’t have that on the return.

Pleasant airline over all. On time, efficient, nice staff and good food.

This flight was excellent in all ways if they could repeat it consistently they would grow immediately

Philippines AirAsia is never on-time flight, delayed 3 hours. Everything else was fine though.

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.

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

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

There were only 4 out of 6 that was checked in online but we’re all able to checked in once at the airport.

Nothing really - no food crammed seats - felt squashed - no entertainment, not even a bottle of water - would never use again.

Phillipines customs is so corrupt. After they made me lose my whole Thailand trip air Asia only made me wait 3 hours to get my bags and did not reschedule another flight. Philippine government treat their citizens like China and makes it horribly difficult to leave, just to leave.
