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!

I was unable to select decent seats, and so I was stuck in the middle seat because it was selected for me

There was a lot of partial tv shows but not enough to last the flight. The food was incredible! The crew were so helpful and patient. Lots more space than what I usually get on an international flight. Very comfortable!

Stingy on the drinks - 15 hour direct flight and could barely get attention for some water

Not many people, so you can lay down on two seats

not too bad but not too great either. Service on all airlines declined ever since covid. Your Delta Stewardess are not that friendly at all. :-(

Always fly with Korean Airlines. Best service great food. Nice and clean as always.

I thought the service was very nice and pleasant. There were no hiccups and no issues so overall a good experience.

It was a pleasant surprise to have complimentary Wi-Fi on the flight

Flight was delayed, we could have been notified earlier and in a consistent manner. App was not refreshing for another passenger to get the latest flight status. We could have stayed and waited at the hotel instead of waiting at the airport had we known the flight was going to delayed for more than 5 hours. The toilet is too tight, and needs to be cleaned more frequently (every hour). The entertainment screen froze, the touch screen not responding to touch. We were upgraded to comfort, it is more comfortable than regular economy seats.

The baggage belt was not updated on the Delta App and was displayed on the wrong belt board. Was not expecting this to happen.

The plan was delayed and left DC 90 minutes late. However, it showed a 20 minute delay on the delta app, then a 12 min delay. It turned out to be an hour delay. I found out where the plane was with flightaware. Stop keeping customers in the dark about what is going on.

Pilots lied about waiting on “paperwork”. Sat in the plane for over an hour, waiting on some papers to be printed according to the pilot and then all of a sudden he says good news maintenance is finally on their way. Maybe they can fix it before we get our paperwork. Ended up missing my connection in LaGuardia and as a result, had a fly home to Lexington instead of the Louisville airport. Then paid $100 to uber to Louisville since it was midnight by the time I got in. I wish they would just be transparent with passengers sometimes and not try to beat around the bush on why things are delayed.

One of the flight attendants was a little cranky. I appreciated the free wifi and plug to charge my laptop

The flight was smooth, the crew was great but the plane was quite old

The flight was delayed 90 minutes The Gate was wrong The Restroom on Aircraft was not clean There was a half used water bottle in my seat

I was given middle seat on this flight and prior Boston to Seoul flight That is a problem for long flights, Kayak system did not give me a change to select my seats and assigned me middle seats regardless of my elevated status in Delta. This needs immediate attention.

The plane was dirty, the seats were torn and broken, the service was the most terrible ever, the bathroom dirty, they will not even serve water you had to request it, the meals were terrible, overall less than Zero, I will never fly Cathay Pacific again.

Despite the crew's rough day, they were all very focused and friendly. The flight was too short for a meal, so no rating on that. Re. the AA app. It still isn't ready for prime time. AA works with Cathy Pacific for international flights to LA and the Aa jump to PHX. But the AA app can't find my trip and this can be problematic with flight delays and regatings at LAX.

Was not able to board flight because boarding pass name did not match passport name and no one caught it.

Had a bad experience with crew member coming back Hong Kong to la the person next to me one of the passenger have taken video and picture of crew member the person that served meal young kid late 20' s 6 5'10 had attitude at his peak anything I asked for I don't know if it was bad day or racial I felt humiliated as people could see difference towards me I no problem with Cathy and my whole family never had one was very disappointed

Frequently flyer number should and could have been put on at the time of booking as I gave the number when booking.

Seats in the absolute back row of the plane even though we booked ages ago :( Crew was awesome though

Great. Efficient boarding process with the face recognition. Plenty of cabin space for luggage.

From BOS to HK, the crew had pushed me to choose the pasta for meal multiple times. It was a bad experience. Without this, everything was good.

The overall flight went well and the aircrew was pleasant.

Average flight for which I paid too much for on a last minute purchase.

Because I bought my ticket from Underpricer, I could not check in online. I could only check in at the airport and that was deeply frustrating because I had to arrive very early. The flight also departed 45 min late and passengers were given no explanations about why we were delayed. I was worried I would miss my connecting flight. Once on board, however, the flight was fine.

Terrible boarding and first class experience. Nice staff but overall disorganized, dirty plane.

The flight was delayed significantly and we sat on runway after landing for awhile. Best thing was the flight attendant, Jenny, in first class, who was very professional and attentive. She was excellent - the rest of the flight was not.

Early departure meant on time arrival. Only real problem was free internet had issues, although chatting with the internet help desk (you can do this via aainflight.com) got the issue resolved.

The staff and service on American Airlines were truly outstanding. I had requested wheelchair assistance for my mother due to her knee issues, and the team went above and beyond every step of the way—from boarding in Boston to our arrival in Chicago. Their care, professionalism, and attentiveness made the entire experience smooth and stress-free. I’m very grateful for the support they provided.

Found that the plane used for this short flight is smaller and therefore the seats are really squeezed tight.

Tv screens and movie selection v good. Friendly staff. They were really worried about max capacity and room for carryons. That is never fun but i had no problem finding space when I boarded.

Great experience. Good dinner and service. FA's were very nice and attentive.

Jill was the flight attendant in first class she was fabulous!! Best flight attendant I have had in years.!! And I fly every other week. Other can learn from her!!

The business steward was absolutely amazing! Smiles and kindness! Wish all AA flights are like this one!

I bought a ticket from Kayak. When I got to the airport, the was no ticket. I had to pay 5X to get to my destination. No response received from Kayak. I will NEVER use them again.

everything was fine. but paying for 1 piece of check-in luggage and denying passengers to board with carry-on luggage which by air line's standards does not fit is not acceptable. when one travels for a longer time one needs to have some essentials

Pearson Airport could not properly handle all the passengers who they needed to process in order to properly get them on board. As a result, I missed the departure of my flight from Toronto. The only saving grace is that Air Canada found a flight that only delayed me by one hour. However, this was no thanks to Pearson Airport!

I had a good experience. I liked being informed about the status of my luggage

The staff could have been friendlier. And Having the flight on time would have been much more convenient.

Old, noisy plane, bad coffee, delayed. Flight attendant was very nice.

We boarded 1.5 hours late. Long wait for the bags when we got to Mexico City. Long wait to get on plane with people mover truck. Friendly staff. They answered all questions as best the could. Such a long, long walk from the plane to customs. Thank you, Michael A. Burris Cambridge, Massachusetts USA

I was forced to check my carry-on bag, which I don't appreciate.

Terrible. Air Canada decided to wait for another flight. Due to the waiting, the weather got worse and connedting flight got cancelled. Air Canada said it was all due to the weather and didn’t pay me for the hotel. Not speaking of 3 hours waiting for my luggage. Never again!

Hard to criticize after the Crowd Strike dilemma. However, when Air Canada says they were "not affected," I expect that is true. My flight delays caused me to miss transportation connections. I understand these things happen, but I don't have to "like it."
