The boarding process was efficient and quick. The seats were comfortable. The food was good. The service was excellent. We had a lovely flight from Seattle on Korean air

Flight crew was fantastic. The aircraft was meticulously cleaned at all times. The crew was continuously checking to see if the passengers were ok.

It was good, I liked the self-serve snacks but it was a little difficult to get the alcohol, which is understandable since I wouldn't want kids sneaking it.

Friendly flight attendants and gate agents. Very clean plane and food was good!

Just a typical domestic poor flight nothing more. There is no food choices in such a flight. Crew doesn't really care if you are on-board or not

When I selected my seats, it showed row 29 as the front row, so I paid extra to sit in what I thought would be the front row, but when I boarded the plane, row 29 was the second economy row. I was disappointed that I'd spent almost $100 more for no actual benefit.

They texted me my gate number and then they texted me again it’s now boarding but in different gate, and the gate was so far from the gate they texted me earlier. I have to run just to get to my flight. They always do that.

You did not put me on a Korean Air flight! so I do not have nothing to say

Wonderful cabin crew!!!!! Food was poor, in flight entertainment was just ok. They need to serve more water on a 15 hour flight--we were dehydrated and kept asking for water.

I’m an extra large person, so it’s difficult to get comfortable in the seat. They did provide an extender for the seatbelt. The staff were very friendly and helpful and all requests for additional water, juice, noodles were granted quickly.

Waited a long time at JFK to board with no information being readily available.Left about 45 minutes late and it was 2:45 AM in JFK.Nothing todo. Second deck of the Airbus is more comfortable or seems that way because there is less people. Food was OK. The food on secondleg was better as we had ordered it before hand. We thought we had did that on the long first leg but we were told we did not. Cabin crew was generally nice. There are people who lean back when eating as they wait for food to be delivered and know no one will check -- drag. TV selection was awful movies OK. Comfortable all in all.

Not enough seat cushion. Butt was hurting especially on long flight. Not enough movie selection. Entertainment was outdated. Coffee served was cold. Other than that flight was good.

Humm, I should have known that the seat I peaked on my flight from Inchon to Manila was designed for a toddler or very small person.

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

Kayak along with airfare assay are attempting to steal my money. Charges are being pressed.

Customer service and attention to details. The food was good.

Better screens, it would have been nice to have more comfortable seats.

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.

Flew on an Airbus 350-900. Excellent aircraft properly cleaned and serviced. Flight crew was excellent plane departed and arrived on time. The A350 has excellent air circulation far better than the 777. I would recommend Asiana to anyone looking to fly in a clean comfortable environment. This is my second round trip flight from New York to Bangkok via Asiana and I will book Asiana again!

JetBlue's check-in was great, but there was an in-flight attendant who was very rude and unkind. I didn't realize that the bathrooms were already locked 30 mins prior to landing and needed to use the restroom. Instead of politely asking me to return, she rudely told me, 'NO, bathrooms are locked! Go back to your seat!' The JetBlue flight was more than an hour delay, which made me almost miss my connecting flight with Asiana. I understand the reasoning, but the action they took to get a hold of maintenance was time consuming. It took them more than 30 mins to get a hold of maintenance and for maintenance to get started. The Asiana flight and crew were wonderful, in general. They waited for us who were delayed from the previous flight before they took off and were very kind to take my checked baggage's info. Seats were a little uncomfortable for such long flight, but service and flight attendants were great! However, my 3 checked baggages are missing! They're lost somewhere in the transition. I'm writing this review 3 days after my arrival to the Philippines, and my 3 checked baggages, where my wedding dress is, are all still missing! I and the CEB airport crew have sent multiple emails to both JetBlue and Asiana, and neither has responded to any of our emails. Although, I was able to get in contact with JetBlue's Interline Department who confirmed that the bags were turned over to Asiana without confirmation details.

We were delayed 2 hours because of a broken seat. Other than that it was a very nice flight.

an he late. super rude gate agent, to every person. spoke down at people.

One of the restrooms didn’t work. The ones that did never got replenished. Flight attendant just sitting there on their phone. No notification that the bathroom was broken so long lines. Apathetic crew.

Both of my flights to and from JFK experienced significant delays. Most notably, my first flight was delayed by six hours due to crew members being affected by delays on a previous flight. While I understand that disruptions can occur, Delta’s staffing and operational planning should include sufficient contingency measures to handle situations like this rather than placing the full burden of those delays on customers. Additionally, the $12 meal voucher offered as compensation was inadequate, particularly given the high cost of food and beverages at the airport. Considering the length of the delay and the substantial inconvenience caused, I believe more meaningful compensation would have been appropriate.

We were skipped when the snack cart passed and then the attendant said we weren’t . I am disabled and was in a row toward the back of the plane which was very difficult for me to navigate. Disabled people should not be forced to walk the plank.

Our flight was delayed multiple times and then canceled at almost 1 in the morning. We are a family of 7, traveling with 5 young children. When the flight we were supposed to fly on finally arrived after waiting all day after an international flight into JFK we were informed our flight was in need of a copilot and once they located one we would take off. Then our flight was cancelled because the copilot was over his hours and they couldn't locate another. They knew before taking off from the previous location that the copilot would be unable to fly. They could have communicated the cancellation of the flight hours in advance. Once they cancelled and the pilot and copilot got off the flight, they joked about it. While there are understandably limits on flight time for pilots, they can still handle the situation in a professional manner. The late cancellation resulted in angry passengers that required police intervention in the airport. It also occurred so late and included other delta flights that after trying 15 different hotels, we were unable to secure a hotel room, they were all booked. No rental cars were available in the area either. We ended up staying in the airport with the 5 children. We made it home after 54 hours of travel with maybe 2 hours of sleep. Our luggage was lost and had to be claimed at the airport at our final destination. This was the worst trip I have ever taken and the worst airport I have ever spent time in. I met two individuals in the airport that were kind and helpful; Tonya Maingot Williams from the can we hel desk that worked to help get us rebooked and home, as well as provide us with care bags for our extended stay in the airport. The other individual was Danielle from Buffalo Wild Wings that was so very kind when we found a place to take our family we were traveling with to eat, all 11 of us and we were able to sit down together to enjoy a meal during such a stressful time.

On time! There were plenty of airport employees who were able to keep us moving in the right direction. The crew on the plane were professional.

Was revoked with Jet Blue due to delay from Kenya Air

WiFi didn’t work most of the time. The usb chargers would work only occasionally for 5 mins and wouldn’t charge after that. Had to keep trying repeatedly at each of the seats in the row.

The crew bent over backwards to thank us for flying and make us comfortable. The food service was quick and efficient. The Captain communicated and said goodbye and thank you as we departed. They really stood out!

My seat had many issues. First the chair was broken where reclining was difficult. My usb plug was also broken so charging was impossible.

There could have been more options on the entertainment section Nothing was available for non English speaking passengers

Crew and food were great in-flight. We had a 2 hour delay, no communication, and just got left in a limbo. The crew arrived late and they were running checkouts on the plane (which is important, but why not doing it earlier?) Cathay did nothing to about the delay, and a lot of people missed their connection flights. I had to run and got stuck at checkpoint, which made my entire trip very unpleasant. Got to my gate 5 mins prior to them closing it.

I was only given 2 meals, and my screen showed that there were 3 meals. Second meal was 1-2 hours late according to the screen.

I've stomach problems after 2 hours of flight, Iris, the flight purser not only did her best to make me feel comfortable, she went above and beyond providing pain relievers medicines and ointment. She look and found a doctor passenger on the flight to provide advise. She even report on ground staffs about my condition and provide wheelchair upon arrival. Kudos to her and Cathay Pacific!

Fast boarding flight on time boarded plane back to front instead of stupid zone groups like US airlines do...

Not enough food for everyone. . Always run out of food when we ask

Flight delayed in NYC and missed Hong Kong connecting flight to Guangzhou. While being given a hotel room and a 30 dollar voucher to eat in the airport, the delay caused a few big inconveniences , a 12 hour delay should have been better compensated for.

Excellent. Planes are a little older and could get some refurbishment, but besides that everything was excellent.

Everything went smooth. All flights were on time No changing gates, . No changing flights . It was like a completely different airlines tha n the last time I used Cathay Pacific . The last flight, 2 months ago, I had before this one was from Philippines also . I got changed in Manila and was told it only added 2 hours onto my flight . My 20 hour return trip ended up being 30 hours return with a 10.0 hour layover in New York with no seats anywhere . Everyone was sleeping or sitting on the floor . Unlike the hotel I was given in Manila to wait for this flight home . I never thought I would use Cathay Pacific again . But I did and this time you were great! I should have complained about the flight and layover from Hell a couple months ago. Consider that I am complaining about that august/23 flight now . Thank you got the great flying experience on my way home from philippines .

I found the boarding easy and my seat was very comfortable as I had a lot of leg room. I am not too happy that I no longer have lounge access even though I used to get it with my TD credit card.

Terrible - flight was flagged for fraudulent payment from being booked via Kayak. Requested to rebook with original credit card or provide new payment. Air Canada stay at JFK did not know how to process new payment. Had to fly from La Guardia 2 1/2 hours later instead with Air Canada.

Could not switch flights. No help from check in Four people doing nothing. Two hour wait on telephone but no other flights available. Overall experience sucked.

My flight ✈️ was delayed by 12 hours causing a disruption to my day

The flight attendant when departing JFK was mean and rude to passengers boarding

Not great tremendous delays instead of arriving at 8:15 pm arrived at 2:30 am next day no food gate changes. Etc

In flight wifi that I paid for was very slow and at times didn't work at all.

On July 1, 2023, I reached out to Air Canada via telephone. After a two-hour hold time, A representative called me back and asked me to confirm my Aeroplan account info. I used the account number, provided on my ticket. The representative told me the information I provided was incorrect. The representative disconnected the call without further assistance. I called Air Canada via telephone a second time and received a callback at 11:06. I started the conversation with the representative by explaining that there was an issue with my Aeroplan account info and the last representative hung up on me. Apparently, my ticket was assigned the wrong Aeroplan number by your own negligence. The issue was resolved by updating my parties' tickets with the correct Aeroplan numbers. Now back to the primary issue, I raised concerns with the new representative about the flight delays and cancelations occurring within the week prior to our trip. The rep assured me if there was a flight delay or cancelation, I would receive an email and be able to change my flight online. I expressed my concern about flying into Toronto and missing my connecting flight due to flight delays. (There were no available seats on any flight to Tokoyo on July 2 or July 3rd from Toronto.) The representative assured me there would be alternative flights out of JFK, taking alternative routes. I received an email notifying me of a flight delay to Toronto at 12:39 a.m. I attempted to change flights using the link provided. When I attempted to click on "CHANGE MY FLIGHT", your online platform showed a pop-up window that stated I needed to reach out to an Air Canada representative. Unfortunately, your service was not open at 12:40 a.m. I arrived at JFK Airport prior to 7:00 a.m. and waited at the terminal counter. Around 7:10, a rep informed me they would hold the connecting plane in Toronto. They even made a phone call to provide me with assurance. I then requested wheelchair assistance to get my 75-year-old mother and begin checking in our baggage. We checked our bags and headed up to the gate. Around 8:45 a.m., several passenger names were called including my party, to inform us they were no longer holding the plane in Toronto. We were informed to go downstairs to make alternative travel bookings. I requested wheelchair services to bring us back to the terminal counters. At 9:15 my travel party was told at the terminal counter there were no flights for us until July 4th or July 5th. I informed the counter this was unacceptable considering, I attempted to change the flight both yesterday and at the terminal counter this morning. They continued looking for a flight to Japan. They worked out arrangements to get us on a flight to Seoul and then to Tokyo, but we had to take it quickly. I agreed. After I agreed to this flight, the terminal counter informed me I would have to go to a different terminal and would need to take the terminal shuttle train. No wheelchair assistance would be provided. I canceled the trip!

The flight was delayed. They assigned us a direct flight instead, We are very happy with the changes!

My flight was delayed, cancelled and delayed again. I lost one complete day in Japan, a very needed vacation. My schedule / itinerary in Japan is now all screwed up. It will take more time and cost to resolve this. So, am I happy with Air Canada; NO!
