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.

Korean Air is unlike any other major airline I have flown with. The grace and respect that the staff has from check in to de-boarding is unmatched. The flight attendants this time were especially wonderful to my five little children. They helped us rearrange to more suitable seating, brought our children’s meals, and patiently waited for them in the aisles when they had to use the bathroom. We felt so welcome and comfortable. I really appreciate the meal voucher when our flight was delayed. I am grateful to have had such an stress-free experience.

It's good overall. Flight was packed. Inflight entertainment choices were lacking.

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!

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

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.

Coming back to America was a peaceful flight everyone and everything was perfect

The staff was courteous and the flight was very smooth. It was so nice to see the captain greeting the passengers at the end of the flights.

The beefsteak on the lunch menu was excellent! I usually do not eat airplane food. I loved it.

Flight was too cold. I wore a regular cotton tee and it wasn’t enough. It was a night time flight so I would have thought a blanket would be provided to passengers. A 4 hour flight and no options for a meal? I flew Asiana the next day from Seoul to Manilla. Same duration, 4 hours. They give everyone a pillow and blanket and serve a meal. Why is United so cheap and holding back meals and amenities? Also, they promote too much gay stuff and DEI in their advertisements. Please be mindful of other beliefs and don’t shove your gay ideology down my throat.

There’s not much to say about a one hour flight. This is a connection from LA to RNO that I missed the previous night due to a mechanical check delay on my originating flight from JFK to LAX. The short flight itself was fine. Instructions from the pilot and crew were per usual. The coffee was barely lukewarm, which possibly was purposeful so we would down it quickly. Bags were already on carousel upon reaching baggage claim, which was excellent.

Flight was warm for first few hours and quite rough

Seat was extremely hard which made even a short 1 hour 20 minute flight fairly uncomfortable.

Improve boarding- the zone assignment and boarding is always a mess- there is not clear instructions of what is going on at the gate. As a meme bet there is no more selection of a good seats when booking. Only offers middle seats to choose or pay extra. There is not more benefit with Amex no benefits at all.

alike schedule and times it’s very good for me, I will stay wad delta for ever

Everything was good except wifi and a leaking drink chiller. The floor was all wet and my bag was soaked. Did not notice until debarking. Have not heard back from Delta. Even though this was leg one of an international flight in first class, they denied access to their Sky Club - very disappointing!

The staff was fine. The plane was extremely tight, and I paid for the wifi and it did not work at all. I was actually going to ask for a refund.

two hour delay and the Delta representative on the PA system was unable to understand

An awesome flight crew. FC seat cushion just doesn’t cut it for a 3+ hour flight.

2+hrs delay without any reason provided and a cramped flight

There was no WiFi available, there were mechanical problems with the plane and we landed at C 124, then the gate was switched to A 26, then all the way back to C126! For a 75 yo woman traveling alone, this was a difficult journey, indeed!

This trip did not start off well. The inbound flight was delayed about 20 minutes. Then, after initial onboarding, the passengers had to deplane due to a mechanical problem. That took about 30 minutes to fix and be cleared. Then, reboarding was chaotic. It took a long time to sort passengers and two passengers on standby were ticketed but there was no seat. So, they had to deplane. One of the flight crew was trying to help passengers figure out a place to put their carry-on bags and that took more time. In the end, our scheduled 10:30 am departure did not actually take off until about 12:05 pm CST. The flight itself was long but we got to Houston. Some passengers missed their connecting flights and had to rebook. Not the best of flights I've had.

Staff were good. My seat was in need of repair, but for a short flight was not problematic. Usual basic snack and drink setup that you'll find on any US carrier. Over, a decent, basic flight.

Complimentary light meal would be appreciated. But great flight crew service on all legs

Poor. Crew allowed children to run around and scream and disturb passanger’s seats.

Flight delayed for more than 16 hrs and no effort was spent to provide an alternate

When I went to check in at the United counter in Barcelona, Spain I had 2 different menat 2 different times in United uniforms (standing around with a couple other employees) ask me if I was traveling alone. The one man asked me 3 different ways if I was traveling alone. I am, 68 yeaers old and have all my faculties. I thought it was weird and it made me feel very uncomfortable. What difference does it make if I was traveling alone or with someone? What if I was a recent widow? That would have been horrible. They never gave me a reason why they needed to know who I was traveling with. I was hesitant to question them because I needed to be on that flight.

Crew was tired as we all were. Pretty abrupt. Flight was delayed. Not as enjoyable as the other 3 legs we flew.

Flight attendants were friendly & good service, food sucks, seats uncomfortable, not many Asian movies or shows flying from Hong Kong

We got delayed three hours and nobody thought to have the bathroom fixed while we were sitting waiting to board? took a full hour to have maintenance come and check it off. Had to shut the bathroom down twice so that the pilots could go to the bathroom. Everyone missed their connections.

My experience was good with United too But only not so good thing was that at Calgary airport I was not given lounge access despite of flying business. Aspire lounge denied it to me, which was unfair I feel

We left over 2 hours late and they didn't even give us a complimentary snack, when getting to the desk I asked if I could be put in a row with only 1 other person or an empt y one I was told the flight was full when the last two rows were empty. All around over it

they were super helpful. Agents at the desk got me on an earlier flight and I was able to get home several hours earlier.

This is a great non-stop YVR-MIA. Very comfortable plane, and no transfer through a city that gets major winter weather!

Terrible…. Reported missing luggage’s with injectable meds that needed refrigeration. Yet, delivery could not be expedited. Luggage’s were delivered 5 days after arrival. The meds were useless as ice pack had melted. So disappointed!!!

Air Canada’s problems are not staff related by and large, no. The problem is tiny jets between the U.S. and Canada - yes, believe it or not they are still “international” (just ask our own Mango Maniac in power in the U.S.). The little aisle is compounded by a design flaw of a “dog leg” starting at seat 12. Woe be unto you if you sit here as passengers and attendants do not have sufficient room to not hit you in the face with backpacks. One thing I will say very positively about Air Canada is you still provide pillows and blankets on transcontinental flights to all, not just the elites. Your tiny improperly designed jets are also a problem flying city to city within Canada also. One can only say you remind us of a “Jet Blue” or “Spirit” experience. Also your luggage space is downright Byzantine! We will endeavor to avoid you and use other U.S. carriers, albeit charging more.

Terrible canceled flight and lost my luggage. Flew me to Halifax. Tgat flight was delayed, had to spend night in airport chair.

Better entertainment & food options more may be adding chicken option or on vegetarian side good quality pasta

My seat was not comfortable. Flight was smooth. Regretfully we had two delays before takeoff

Amazing service, with enthusiastic crew members, and some breathtaking views of Vancouver. No IFE though, as it is only a 1 hour flight on a regional Turboprop jet.
