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.

I like the landing which is nice and safe, seats are also comfortable

Staff on board were good - food was fine tasted good - tv was old 1970ts in seat back but hey it was a 2 out flight so no drama

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

The customer service was excellent. They noticed that our connecting flight was scheduled too closely for us to complete customs, so they changed the flight. Our initial flight was delayed, and they were able to get us on another flight, all without charging us any additional fees. I would fly them again anytime!

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.

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 good took off on time arrived early. Crew was awesome and did a great job. Very helpful and courteous. Bags arrived super fast with no hassles. Great flight!!!!!!

The flight to GES MNL sucks, there was no entertainment. There was no footrest. So the business class seat was not comfortable.

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

Worst airline. They had 3 security checks just to get onboard and no notification prior. Had to throw away any liquid bought at duty free because one of the security checks was prior to boarding the plane. My onboard media console was not working, the flight attendant said they will check on it but did nothing. Pretended we did not ask for it to be rectified for a 17hr plane ride. Horrible experience. My first and last time taking Philippines Airlines.

The biz class to sh doesn’t even have. Tv screen , seats uncomfortable, food terrible and bathroom dirty

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.

The return flight has been a nightmare. I am stuck in Singapore right now because PAL has not managed to resolve my return to Manila. The engine blew up on take off

Good one is its safety. Taking off and landing are good. The bad parts are the managements at airport, especially in Manila. It's horrible.

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

Everything was ok except that one of my checked in baggage which was new lost 2 of its wheels and so I filed a complaint and hope they would give comoensation. otherwise, everything was good!

Passengers seemed to ignore zone boarding which added some chaos. Actual flight was fine. CebPac charges for water and snacks. De-boarding involved steps from a plane, then a bus and a very long ride to the terminal. Baggage signage was updated after luggage came on the carousel, so this was confusing.

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

The seats were dirty. Food on tray table. Late on my first flight and almost an hour early on the return. My driver was unable to adjust and I had to pay for different ground transportation.

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

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

Bags lost for the second time. Will not fly with Cebu Pacific again.

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.

The flight was delayed for 3 hours and I missed my transit flight.
