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.

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’d have rated Asiana good except an unfortunate incident in which I felt one of your employee didn’t really help us. During the first leg of the trip, the flight from LAX to ICN, I left my backpack on the plane. When I realized, I reported to one of your employee who promised me that it’d be taken care of, that my backpack will be there at HCM city. When we arrived there, HCM people had no idea and my backpack was still at Incheon airport who denied any knowledge whatsoever. I was left in the cold and felt helpless. I was very disappointed. I’d like someone to look into this and let me know.

I am thankful that I was able to fly using Asiana

It was my first time flying Asiana but i was very pleased with how professional and understanding the flight crew is with little kids. One flight attendant held my 3 year old daughter’s hand guiding her to the exit after landing while i had my hands full with luggage and my infant. She was very helpful.

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!

It was great, but my bag was not loaded onto the connecting flight. I'm currently getting it resolved. If this isn't a problem, everything else was excellent.

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.

The plane hasnt left im stuck in seatle still my flight has been grounded for almost 5 hours

My luggage didn’t arrive with my flight. Flight was delayed by nearly 2 hours while we sat on the plane and I almost missed my connecting flight and subsequently missed the last train from the airport so it took me another 2 hours to get to my destination after arriving, Crew skipped me several times when offering beverages, and I couldn’t get their attention at times because they wouldn’t even make eye contact with me. They didn’t give me a form for disembarking so I had to go to the back of the line after waiting an eternity for immigration. Paid for on flight wi- fi that didn’t work for most of the flight.

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.

Check in process was excellent. Lounge needs improvement. Food not palatable and no good choices.

The check in staff were fantastic. So so helpful and nice.

Apart from a departure gate change, a good experience with professional, friendly staff.

Excellent service from check in/ bag drop counter staff to flight attendants. Food was great. Seats are nice. Excellent airline.

I like the pleasantness of how courteous and friendly and helpful everyone is

A shameful national carrier. Service has gone down from the highs of a decade before. You don’t feel the Filipino hospitality. It’s an aging fleet. Nil comfort, and I flew premium economy.

Excellent! All flight related was memorable ! My first experience with Mabuhay Lounge,,, not so good

Everything was fantastic!!!! I can’t wait to fly home 😃!!!!!

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.

Short flight with limited entertainment wasn't that bad. Staff was friendly and plane was clean. Meal 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.

Terrible. Not to be trusted. I missed a flight from Manila due to 3+ hours in traffic to the airport. Customer service was rude and unhelpful. I booked a new flight. The cost was steep. And on my credit card online account, Cebu Pacific charged me for two tickets, yet I'm traveling alone, one person. They are impossible to reach and pathetic customer service. My credit card company is looking into it. NEVER, NEVER fly Cebu Pacific. They will rip you off. They don't care, they don't have to. Fly another airline in the Philippines.

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.

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.

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.

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.

Service it was good Lower airfare and discount for loyal customer

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

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
