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.

I am thankful that I was able to fly using Asiana

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

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.

It was amazing with great service. But the seating could have been better if there was ample arm rest areas

Well, I needed to make a change to my flight and I called the airline and they said yes no problem $700 and we can do that and I agreed to it so they canceled my tickets and went to rebook and came back after being on hold for an hour and a half and said I’m sorry, sir. There was an error. It is $2800 Now and I said never mind. I will just use those flights and she proceeded to tell me that they already canceled them because I said I was interested in doing the change. I told her yes for $700. I was fine with doing a change but not $2800 so give me my tickets back and she proceeded to tell me that she could not do that and I had to pay the $2800 to get my tickets back that I already spent $2800 on. So I had to book tickets on another airline to get home And that cost a lot of money too. I’m a little pissed off at Philippine airline right now because of what they did to me and I’m not sure I ever wanna fly with them again. I’ve flown with them plenty in the past, but this just really put a bad taste in my mouth.. Not to mention on my way there leaving Seattle going to Vancouver. I got to the airport three hours in advance and they had booked me through Alaska Airlines to do that little trip. My connecting flight would leave about six hours after I got to Vancouver BC. I stood in Alaska Airlines lying for a little over two hours and then they proceeded to tell me that they couldn’t check me in because I wasn’t there an hour in advance. I kept telling the lady at the beginning of the line that I was afraid they were not gonna let me in because it was taking so long and she said oh don’t worry about it. You’re fine you’ve got time. Well I ended up spending $600 to get to Canada that night just to make my connecting flight because Alaska air wouldn’t do anything and Filipino Air told me it was Alaska air problem but Alaska air said since you booked through Philippine air, we can’t fix it. I had about 50 minutes to make my flight, but they refused to check me in because I wasn’t there an hour in advance yet. I’ve been standing in their line for about two hours and 15 minutes.

Manila airport is a dump. Very dirty and not comfortable at all

Flight left on time landed early, Crew was great , never an easy job. Bags arrived in a timely manner . Good job all in all.

Flight was cancelled and rescheduled to 205 in the morning at the peril of passengers. No hotels provided by the airline. Passengers left stranded at airport. Not acceptable. I was able to get a hotel at my own cost outside of the airport. No reimbursement. Won’t be my choice in for future travels.

Uncomfortable seats for international flights. No usb charging yet they want you to use your device for entertainment. Very poor.

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.

I’m 6’2” and the seats were too close together for my knees, very uncomfortable.

I thought it was inappropriate that crew let some passengers in the back in full rows move to empty premium exit row seats when others had paid a lot for premium seats.

When on flight the crew was great. The checkin was also great. What Philippine Airlines need to improve is the boarding process and being on time it is bad when the times I have flown with them they are always late which costs me more do to additional parking fees missed connections.

Most passengers going to Dumaguete early are tourists who are some booked thier ferry online. Mine was wasted because of delays cause by waiting on runway before taking off and too long before they let us go down...I could still make it in time if they let us go down early. We are just there waiting to go down the plane for 10-15mins.

We were allowed to board early, seats were spacious and we arrived early.

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

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

Delays on the tarmac, uncomfortable even after paying extra for premium seats. Bags lost in transit, no compensation provided

Delay and flowing long wait for leaving the aircraft after landing. IDK, if it's worth.

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

Terrible, I will never ever ever attempt to fly on Cebu Pacific. I understand that it’s a cheap flight option but they take cheap experience to the next level.

better handling of the checked in luggage. they destroyed mine

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.

Not a good experience. They did not have the food I ordered in advance. The crew is not offer a second snack on a 5 hour flight. The WiFi was either not working or was very difficult to connect to.

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

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.

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.

Nice n easy ride but if they extent flight to El nido instead of Puerto Princesa so have not go go through 5 hrs of windy road

The leg room was not made for corn fed Americans.

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.

Clark security personnel are absolutely the worst. I was threatened by their chief of security for asking a question about what is allowed as a carry on.
