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

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

long flights are difficult but the crew and amenities made it a very good experience

Our seat row plus one ahead and behind we're completely overlooked during beverage service...

Need to have space for Cary on when traveler boarding any zone

An International flight from Cebu to Incheon was delayed the night before without a proper explanation. Same thing happened from Incheon to Cebu in the first leg. I will not fly Korean again. And I will ensure Delta their US partner hears about it. This is a routine by Korean to delay flights from and to Cebu via Incheon.

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.

everything was fine, would have liked better food but it was warm, great choices for movies

Unlimited drinks and snacks on this long flight. Very courteous Korean staff !!!

I like it when the plane have waited for passengers like us who are trying to catch the plane. Detroit was my mom's port of entry we spent too much time looking for our luggages at baggage claim which no problem. But then the problem occur after the immigration when the homeland security agents forgot to give us our passports which it took so long to find them and I was very anxious because we might not be able to catch our flights but luckily the plane to knoxville still sitting there and waiting for us. Praise the Lord for everything.

I took several flights that day, this was the only flight that was absolutely freezing!! It was so cold.

This was the best airline I’ve ever taken. The staff are amazing. The food was great. The pilot was phenomenal. I would highly recommend this airline.

Uh there was a delay, because of the weather. And what took usually an hour flight to Louisville took about 6+ hours. Flight got canceled

I had to get rerouted because the weather delayed my flight enough to miss both of my connecting flights. I select nearly 2 hours on customer service trying to get rerouted and had to miss my first plane which took my luggage to San Francisco. Luckily, customer service sent me to the same airport but I had to ride 12 hours in economy after I paid extra for premium economy. Totally sucks that I overpaid. Customer service and airplane crew were great and really helpful though. Although I still hate how small the seat was, especially since I'm smaller than average, I can't imagine how much it would suck for an average sized person.

Flight attendant took good care of my mom as she boarded on and off the aircraft from her wheelchair. I did not care much for the food nor the movie options Available. I appreciated the increased legroom available in economy. This was one of the main reasons we chose the airline. Overall, the good value and I would fly again.

Cabin crew were excellent in taking care of my mom as she boarded the aircraft from her wheelchair. Did not care much for the food served.

I stopped flying with United back in the nineties. Today's experience reminded me of why.

ANA was fine. LAX has some major problems. I needed a wheelchair and BKK and Narita were very good. I do have to remember NOT to tip in Japan. LAX however, was poor. first the attendant wasn't able to push me. The next person left me stranded in several locations. They would just leave me where ever they felt like; No logic to these locations. finally when we cleared immigration, they (there were several people who didn't seem to care about their job) left me in a large room with a baggage carousal. I tried to locate my luggage to no avail. meanwhile my connection was getting closer. I finally talked with Emir from ANA and he showed me to my carousal which was located a few rooms away from where LAX personnel stranded me. Emir also found a good wheelchair attendant to take me the rest of the way. Without Emir from ANA, I would still be stranded, given the amount of care shown by the first wheelchair attendants.

Wonderfully pleasant experience. Good meal and beverage selections. Professional air staff.

Seat width can be a bit wider. not nice that they charge extra for the window seats. online check in can be greatly improved. in other words, their online interface is bad.

Seat width can be a bit wider. not nice that they charge extra for the window seats.

I have a Peanut Allergy and the Steward staff were very accommodating in ensuring my safety as my allergy is life threatening. Very professional and so vested in their profession.

very professional and very attentive to my Special Needs as I required a Wheel Chair and assistance to board

Very noisy and careless crew on this overnight flight. They should understand customers want to sleep

Everything was fine and I have no complaints or things to note.

The flight was delayed for 30 mins. The overall experience was good.

The economy seats are much indeed roomier. Meals needs improvement.

flight delayed 45 mins - missed connection - 1 hr layover became 8 hr layover waiting for next flight -

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

Baggage delayed for 2 days and still chasing for reimbursement of basis items. Very horrible customer care service.

Horrible airline. Missed my baggage and don’t want to reimburse for the basis items. Pathetic customer service

Compared with other carriers business class for an overnight was not worth the extra expense.

Seats were comfortable. It’s was so cold and very uncomfortable. I paid 2000 miles for wifi service that was choppy the whole flight. Would like to be reimbursed for my miles Food was so disappointing. Three cold and terrible meals for $3000 round trip. This needs to be better.

Generally good. The aisles have gotten narrower which can slow down boarding. Flight crew was great! Healthier complimentary snacks would be appreciated. Due to earthquake in San Francisco we had to circle in air space for a bit but then had a smooth landing. I laud the flight crew for their patience ;)

Easy to board. Flight was super crowded though so I didn't sleep well on that cross country red-eye flight. The aisles seem ot have gotten narrower and the seat smaller whn luggage and people are getting bigger so it would be AWESOME to have more space and breathing room in general ;)

Excellent, professional, actually on time which is rare for late flights. Decent food. I love the new neck pillows! Nice, simple upgrade from the old ones I wasn't sure where to put. I wish they would allow more time for rest. It's a red eye 7 hour flight and meal service was about 3 hours.

We boarded but then sat there waiting on some missed connection people to get on so we sat for about 15 minutes for that. Then we sat again because the passenger manifest was wrong and they had to figure it out before we could leave. That took about another 20 minutes or so. The crew was working hard to figure it out so it’s not their fault. It ended up being a system glitch where someone was upgraded to first class while another person was also in the same seat and it just created a mess that took a little while to figure out. They literally went to every person on the plane asking their names to see who was sitting in the wrong seat. I also hate the entertainment that must be watched on your phone or tablet. Just give us setback screens. It’s so much better. Almost every Delta flight has this now and it is so nice to have them. The crew did a great job. I have no complaints from them. They were very hard working, even with the mishap and a disgruntled passenger.

We were delayed in Toronto on the tarmac for THREE hours with no clear indication as to why except that it was not a safety hazard. Pilot did apologize more than once but even he was unable to explain why exactly we were delayed. I overheard the stewards saying that the captain was very frustrated with the situation as well because he was not able to explain why except it had something to do with water supply or system on the aircraft and now we needed to wait for an engineer to approve the aircraft for flight. It was very frustrating and distressing as a passenger and we should have been given complimentary meals at the very least.

Flight was cramped with every seat taken. The food was fine, nothing crazy to write home about. The plane felt dated and needing some TLC, the button for the window shade didn't work and there were no AC outlets to use. When communicating with staff all except one nice lady never seemed happy to help me almost like I was bothering them when asked for things like a glass of water or a snack. The flight was overall fine. It did what was needed which is get me from point A to point B. But it certainly was not special. I don't expect much in economy but I believe economy on a host of other airlines is more memorable and better experience.

Overall poor for me I paid extra for seats with leg room and my regional flights exit row seats have less leg room then the others that's money that could have been saved and on my final flight home the flights air was not operating it was unbearably hot in the cabin I will be contacting United and filing a DOT complaint

We paid extra for the seats with extra leg room. But we were not allocated the seats with extra leg room nor refunded the money we paid for the seats.

1. Nowhere to sit at the gate D4 2. No control of lining up in different zones 3. People pushing in during the line up of zones. 4. Certainly not in a dignified manner.

Everything went smoothly. I appreciate the selection of free movies.

I like the friendliness of the crew members. I think the snack could’ve been better instead of a small package of pretzel. I like that they offer me something to drink.

The TSA agents in Phoenix were incredibly rude and confiscated belongings that we wanted to check. The flight got changed without our knowledge to a worse situation. The whole thing was terrible

Air Canada was great! From the airport at Montreal to boarding to the food on board the plane. The crew was great too! There was a slight issue with some other peoples’ tickets that I overheard about but the crew handled with care immediately to ensure everyone was comfortable and we could takeoff! Great experience with Air Canada

My experience with Air Canada was good. Great customer service… only a few delays and issues with the tunnel to exit the plain. I did not appreciate that we arrived at terminal D and had to go to terminal E to get the bags/ luggage.

PDX staff was great and we arrived on time in YVR.

They announced before boarding that the flight was full and there would be limited space in the overhead bins and you could check in for free. We did and after we boarded the plane found it was not full and there was plenty of space in the overhead bins. I’m not sure why they made this announcement.

Front desk attendant wouldn’t check me in even though there was not a single person in line. Made me use the kiosk. Kiosk had an error (of course) no baggage can be checked at this kiosk please see attendant. Then I had to wait in line for the same front desk attendant waiting for 5 people who ended up coming in front of me while I tried to use a broken and useless kiosk. Finally after checked in, wait 30 min to board all the way to zone 6 and they would deny me even after all the zone 1-5 people already went. Just literally making us wait to board so they stand there doing nothing for 5 minutes. Just ridiculous and awful customer service. Fly with literally anyone else

They are a great airline, and i enjoying flying with them. However my experience with booking through Kayak was a horrible experience. With all the restrictions and glitches of website. My entire bookings by kayak was wrong. And there was no possible way of fixing anything with them, because they hand over responsibility to the airline after purchase is made. Will not be booking through Kayak again and will inform my family and friends not to as well.
