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.

The business class is excellent. I loved the food, and the crew was very attentive and professional. From boarding to arrival, everything felt smooth and well-organised.

Lousy entertainment system. Crews are excellent. Meal is just mediocre.

Great service and comfort level. You can have more of vegetarian food options.

It’s great, long flight and arrive safe at destination

Everything was excellent as I expected. They also had a very caring crew. I had a headache and asked a Tylenol. The crew members kept checking with me how I was doing.

I can't believe they put my wife and I in the two middle seats! It is a very long flight and we had single flyers on either side of us blocking the way to the bathroom! There's no reason to not give one of us the isle seat so we could have managed bathroom needs and snacks with convenience. So I think very poorly of Korean air to put us both in the middle, I've never had that happen before and will probably avoid this airline in the future because of this. We tried to have them change it but they didn't so you pretty much lost a customer because of it.

There could have been better spacing of the passengers, it was crowded in some parts of the plane then other while rows were empty

Plane took off on time and I had the whole row to myself!

One of the flight attendants stepped on my foot. I was on the aisle seat. A lady inside needed to get out. So Instood. Just then, a flight attentendant came wuicklybtheoughbthe aisle and stepprd on my sock covered toes. I let out a small sound. She stopped momentarily, but didn’t ask how I was just took off of the aisle. Never came back to see how I was. Fortunately, I was not really hurt other than a slight soreness in my toes. But I found that to be very negligent.

This flight was a superior flight in all regards. Extremely pleasant experience.

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

The staff hold my luggage to steel and exchange my stub, i was very disappointed.

Kayak uses scammer sites to steal money from their victims.

Felt like the oldest plane in Asiana Fleet. Screen was 5-6in only and no charging at all. Movie selection wasn't great.

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’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!

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.

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!

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..

All good and friendly However the blasting of music at take of and landing is so annoying and can’t hear anyone speaking .

Terrible customer service. My last choice to fly now if there is no other options.

For budget airline, it’s not bad at all. It’s definitely value for money. I added on the priority check in and eSIM. It’s well worth it.

First time flying with VietJet Air is so so. Check-in process for domestic is okay and easy but during our flight back to Manila, the ground staff at Tan Son Nhat International Airport weighed our hand luggage before boarding when in fact, it should be weighed during the check-in process. They are very strict in terms of the 7kg hand carry it’s either you’ll pay extra, or leave things behind.

I was unable to check in online so had to line up at the airport. When I got to the counter? The staff told me I had to check my carry on luggage, which cost $70. When I boarded the plane, I saw many suitcases that were bigger and heavier than my carry on… so not sure how they were able to bring them on and I wasn’t …

Waited for 1 hour on tarmac because they couldn’t locate a tow truck. Flight was fine once we eventually took off.

Late departure, late arrival, and personal items on laps during takeoff and landing. Departure gate opened on time, but no direction as to whether to board at front or rear of plane based on seat number. Fashionable staff with sunglasses inside the plane and cockpit remained for ten minutes after the boarding complete announcement. For a scheduled 80 minute flight, adjusted to 65 minute as noted on takeoff; the total time on the plane with delays was r more than two hours. No confidence had there been an emergency that anyone would have been able or aware of what to do.

The flight was OK, but you need to warn passengers going to Vietnam that the full first, middle and last name needs to be in the issued visa, At least 5 passengers on that pane did not have that. We all had to pay $298 each to some agent to amend the visa. At least one lady could not and was left behind.

VietJet is a discount airline like EasyJet, Flair or Spirit. I flew 3 flights in 2 weeks and all were Airbus 321's. 2 of the flights left and arrived on time and 1 left and arrived about 45minutes late. Seat pitch in economy is 29" but exit row seats have super-generous leg room. There are no power ports or entertainment of any kind. Food is best purchased on-line before the flight but there is a limited selection available in flight - cash only. The aircraft are clean and the airline is run as well as any other airline that specializes in economy passengers.

Our flight was 3 hours delayed and the airport was hectic as our boarding pass said one gate while the digital screens said another gate. Attendants were clueless and said to watch both! Vietjwt cared more about selling their merch than even providing any water for the 2 hour flight
