Overall, very uneventful and pleasant experience. Most importantly, no delays.

The flight crews were extremely professional, helpful, and courteous. Departure and arrival times were accurate. No delay. I will use K airline again. Thanks

We were seated at the back and that was very uncomfortable for me with the turbulence we experienced on our way to Chicago.

I enjoyed flying on Korean Air. The service was great and the food was yummy. They served white fish.

I enjoyed flying on Korean Air. The service was great and the food was yummy, especially the bibimbap and cold spicy noodles. The only thing that bummed me out on this red-eye flight was that my seat did not properly recline so I was not able to sleep.

On time and flight crew are always so happy to help and always smiling unlike other airlines.

Great crew, decent food Charging plugs were broken on both seats next to me. Only the USB port was available, and that charges, very, very slowly. Seat was also broken, it would not lock into position when reclining.

Korean Air had great service and the Bibimbap dish was the best airplane food I’ve ever had. It was a long flight so in between the two meals they served customers could get Shin ramen. The flight attendants let my children use a pair of nice headphones for the flight and had earbuds and slippers for all the adults. The flight was long but the time passed by relatively quickly because they have many great shows in their entertainment TV. I watched the BTS Love Yourself and Speak Yourself concerts 💜

Stewardess are nice. Food could have been better and should have a better dessert. They do not offer scotch or beer. You have to ask for it. I also was not happy that you do not serve ginger ale and or cranberry juice. This is my first time that an international flight do not have this. I go home overseas every year and when I travel through ANA, Delta, Qatar, JAL, Asiana Air, United Air. they all serve this two very famous drink. You do not have a great snack tray.

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

West Jet has a horrible boarding process and the seats have no cushion.

Everything went smoothly. I didn’t like that when I booked in the main cabin my wife and I weren’t seated together. One would think when booking on an option that allows picking your seat. They would put you and your travel partner together. Had to call to get it sorted. They did fix.

All in all it was a long flight in economy class. There’s only so much comfort one can expect on a plane. The seats felt exceptionally hard and as an over 6’ individual I’ll seldom feel great about legroom. The food was good and the flight crew was great. The headphones provided for the movies were terrible, though

The gate area was incredibly short staffed, with one representative manning 4-5 flights, which caused a 3 hr delay in boarding even though the plane was all ready to leave. Other flights also were delayed because of this. The flight crew was awesome and I feel bad for the only gate worker on call, but Delta needs to hire more employees.

Very frustrated with boarding gate crew. She announced the plane was small and they would be limiting us to one item to carry on. Not a problem for me as I understand the tiny planes have limited space!! Not the case here! It was a rather large plane and had plenty of room for bags! So because I don’t want to be one of “those people” who ignores the request to check a carry on I did so asking if I would be able to pick it up at the bottom of the ramp on arrival in Knoxville to which she responded “yes”! Then I watched as every other passenger held onto their 2 items and boarded!! Then when we arrived in Knoxville our 2 carry ons had been put with all the other luggage and we had to go to baggage pick up and wait for all the big checked bags to come off the carousel! So she lied!! Frustrating. Next time I won’t be so nice!

It was a good experience except when boarding a female flight attendant did not go out of her way to assist my teenage daughters in finding space for their carry-ons after their compartments were full.

On time departure, smooth trip, flight attendant told through passengers the gate we would arrive at and the gate our outbound flight was departing from. Early arrival

Checking in at the airport the agent only booked the first keg of my trip and had my checked luggage going to the airport with a layover! Never was issued a boarding pass for the second leg or received sticker fir my checked bag. All was well in the end! Delta agents helped to resolve the situation!!!

Delayed due to an ill passenger after loading. Not preventable on Delta's part. Was in first class. The seats are becoming worn and detaching from their velcro attachments. Only got snacks on flight. The attendant was not the friendliest.

I would fly again the whole experience was great. The only feed back I can give that they don't do that American Airlines does is the crew there is more humorous with boarding and thank their passengers. It makes it more fun to fly with them. I would however fly Delta again.

Overall the flights pretty good. The snacks we’re good and they were plenty of them. Both boarding and deplaning went quickly.

Delayed abs delayed Gate crew giving poor info - we are definitely leaving at —- Ultimately to cancel flight after 4+ hours of delays Just cancel it earlier

The flight was scheduled to depart DCA at 12:30 pm but was delayed twice on the ground so that we were finally scheduled to depart at around 4:00 pm. Once we boarded, it was announced that takeoff would be delayed again to fix a hydraulic problem which delayed our eventual takeoff until around 5:00 pm. Once we departed, it was a smooth flight back to ORD. We did not get any explanation about what caused the original significant delay. In my experience, this happens frequently with AA.

Lots of weather delays that were poorly communicated and managed. I get there are weather delays but they didn’t make it clear what was happening or comfortable on the plane

Everything was on time; the flight attendants and the gate personnel were very pleasant and helpful.

Our second leg to Jackson WY was unable to land due to weather. We were flown back to Dallas after stopping in SLC. We were given hotel rooms and vouchers. We were told that we would be back on the same plane in the morning. Instead we were given a different flight with different seats. Not a good experience. No one knew what was going on.

Perfect flight. On time departure and early arrival. Smooth flight.

Awful! The flight was delayed and we sat on the plane in DCA for an hour because fuel was out in the wrong part of the plane and would not be accessible during flight. So the plane had to be refueled in correct tank. They also allowed someone to get off of the plane. This delayed my six hour flight by an hour and made me miss my connecting flight. I ran to new gate and American Airlines agents new about the delay and even knew that I was trying to make the connection. They knew thru communication with my friend while in flight that I was in the airport and running to the new gate and they still closed the gate and refused to let me on the new flight despite plane still being at the gate. It was horrible and I had to be rebooked on a flight for 24 hours later. This has been a nightmare and if American Airlines can cause customers to be delayed and then have zero empathy as having an on time flight was more important to them than helping a customer who was delayed by no fault of her own, then it's seems that it's not a company that I want to continue to give my loyalty to. I'm so disgusted.

Help was available but timing was bad in my case

It was a horrible snow storm, but updates were inconsistent and the app never displayed a remotely accurate time or gate until very close to boarding.

Everything went smoothly and as expected. We were on time and one flight arrived early.

First time flying Air Canada and the trip was very pleasant! They did a great job getting us out of Toronto and into Rome (early!) For an international flight it was very enjoyable.

This is not a Business Class equipped airplane and even the crew apologize before take over BUT BUT Air Canada charged full business class fare

All was good, except our baggage was lost for most of a day. We are thankful that it was found quickly and delivered to our hotel. Rouge was fine outside of that problem.

You do not have a space for flight cancelled. BUT!!! Air Canada handled it great. Was booked on another airline for the next day. The original flight was booked solid. But he precheck by the maintenance found a mechanical problem and the plane was not safe to fly. It was an inconvenience to have to wait until next day but I would rather arrive safely.

Very good other than we have to wait for one crew and we’re delayed and the pilot and his co- pilot has to make a difference to be right on time arrival. Disappointed about no food service also.

I had written all my complaints on my trip from Grand Junction to Denver so I will repeat it here! I was absolutely appalled that I had to pay for a regular seat that I choose 24 hrs before boarding! Also I checked my large bag which I had to pay for as well, and by the time I boarded all the room in the bins were gone so also had to check that one. I noticed people pulling out oversized suitcases, bigger than the measurements stated for carry on, and also large pack packs stuffed full! So these people were taking up 2 or 3 spaces that the rest of us should have been able to use but couldn’t! NoTV on the flight! Thankfully I had downloaded the United Airlines app and was able to watch movies on my phone. Don’t remember the last time I flew in a plane with no movie screens!

I was appalled to have to pay for just a regular seat when I went to book 24 hrs before my flight! Because it was only an hour flight I didn’t choose a seat from Grand Junction to Denver, but I did for Toronto and had to pay just to choose a regular available seat! In my 60+ years of flying this was the first time I have heard of this. Also, allowing people to bring on “huge “ suitcases, not carry on size, but much bigger, and then a large pack pack stuffed. So they take up all the room in the overhead bins and if we are later boarding, there is no room so we have to check our small carry on. I have already paid for and checked in one bag! I certainly will not choose to fly with United again unless it is the “only” airline available!

Easy boarding, roomy seats, plenty of good food, very helpful snd friendly staff. Very smooth flight! Only thing that could have been better was to have cranberry juice. Women like this as it helps avoid UTI’s and not as sweet as other juices.

The crew was friendly, the seats are too small. Air travel is barely tolerable anymore.
