Not having a five hour delay with little notice! The crew was very kind, though, and just as tired as we passengers were. The flight didn't depart until nearly 1 am...and no reason was ever given.

Great flight from Seattle to Phoenix and to Chicago-Midway from Phoenix

Very smooth checking in our luggage with a super pleasant SW agent. I enjoyed a fun entertaining movie.

The seats were a bit cramped and worn, but otherwise okay.

I really like open seating. I hate that I've heard this is going away. This is one of the unique things that makes Southwest my goto choice.

They sent us to an airport way out of our way because they canceled our flight with no reason

I love no assigned seats and bags fly free. If Private Equity gets their way and forces Southwest to change they will be everyone else and I will stop being loyal to them. DON'T CHANGE YOUR BUSINESS MODEL!!!

Since the flight wasn’t full, we had some extra room. Crew was great

The people of SW Airlines really make it nice to fly.

More assistance and clarity for travelers with gate checking and lap children

A smooth flight; a little cold on the ground and then suddenly heated when in the air; legroom on the 737-800 worse than on the outgoing flight, on 737-900. Much prefer flying Alaska to the northwest than flying American anywhere!

The flight was canceled and dumped everyone in Albany. I still haven’t received reimbursement for transportation for getting to NYC or appropriate compensation for the cancelled flight.

My experience was significantly impacted by problems in Seattle with luggage check-in. Apparently, Alaska Air was significantly understaffed in this area for the number of passengers for that morning or they had issues with the machinery processing and loading the baggage. Upon tagging my suitcase, I was sent from one drop-off area to another and yet a third on a different floor. The line to do most of this was VERY long and moved quite slowly at first--I just barely made it on time to catch my flight even. though I arrived at the airport an hour and 40 minutes early. Then when I arrived in Charleston, my bag didn't arrive on the carousel with other luggage and I had to spend extra time tracking it down.. The relative who helped me out at SEATAC said he had never seen the airport so backed up and he travels out of that airport frequently. It was a very stressful experience, and very disappointing.

NO ENTERTAINMENT OR WIFI OR FOOD. ONLY WATER TO DRINK AND SPICY PRESTLES TO TAL CHAEOS AT CHECKIN

Boarding was smooth, the crew was kind and friendly, and even though we were in the Saver class, the seats were generous enough for my daughter to nap on me and I had enough room to recline and sleep for our overnight flight. If I had stayed awake I might have quibbled with the lack of a true meal, but the snacks worked for me and when my daughter was hungry (as she did NOT sleep), the crew took care of her. There was room for all of our bags on a very full flight, which was nice. It has been awhile since I haven’t checked a bag, so I had worried.

Customer service of one flight attendant, impersonal to asking questions

Someone rebooked my Alaska flight to a much later Delta flight. Now I am sitting at the Seattle airport after a long international flight and have to wait another 4 hours even though I would have been able to catch my initial flight

I was very surprised that at the Seattle airport, Alaska's main hub, that the gates were very small and very close together, and it was very hard to discourage between my flight, and the flight next to us going to Boise and the flight next to that going to Denver. Denver. The audio for all three Gates was at the same level, and almost impossible to differentiate unless they actually said their flight number and location. Location. People tried to get on our plane, before they were ready, because they were confused about the Denver announcements. We were on a Boeing 737- 800 00, that must have recently been redone. It actually had USB--c ports which really surprised me. The Apu was out on the plane, so when we got on it was very very hot. A lot of people were complaining. The gate agents were very professional, but it was a lot going on and even though there were two of them, I think they could have used another person to help them. Mandy was particularly helpful in getting me a window seat. Flight crew was up to the usual Alaska airline standard, which is very high. Can we please get another snack then garlic pretzels? It would also be nice, if they knew ahead that the flight was full, to offer to let us check in our bags for free at baggage check, and not at the gate!

On time, good seats, not overly full, up beast positive crew.

Airport security lines in Seattle were awful. The only staff that was pleasant and made the trip more enjoyable was the young woman at the gate in Seattle. She was so pleasant and helpful. Flight attendant on the plane seemed like she would rather be anywhere but on that plane.

My flight was delayed by 4 hours in 30 minute increments. The gate agents were amazing but the communication was not. We were told that there was a maintenance issue but they didn't know what it was. That didn't inspire confidence. Then they said they found it and it was fixed and the pilot just needed to sign off. Then the pilot needed to talk to the other pilot from the arriving flight and we'd be fine. Then we were waiting for the pilot to call back. Then the maintenance issue wasn't fixed. Then they decided we were getting a new plane (why didn't they decide this earlier??). Fine. But then they announced we were changing gates AND terminals. And we were boarding in 20 minutes. So we all had to run to the new terminal gate. We could have taken off at that time, but we then had to wait for all the people who rebooked on a different flight to book this flight again. That took 30+ minutes because there was only one gate agent. When everyone ditched this flight, I saw it as an opportunity to upgrade to comfort. Delta, the greedy jerks they are, charged me $121. After their delay, their fault, their issues, couldn't even discount an upgrade. They only handed out $12 meal vouchers for the delay. I can't even get a snack from starbucks for that.

Love me some Delta. One of the few airlines to recognize and support veterans. Easy boarding, flight was on time and arrived early and the flight attendants were excellent on this flight.

We sat on the runway for over an hour before departure. That was unwelcome.

Crew was nice, meal was good. Entertainment had to be rebooted 3 times and still did not work. Turns out there was residue on screen, it needed to be cleaned to prevent the touchscreen buttons from continuously activating. I had entertainment for the last 45 minutes of a 5 hour 45 minute flight. Really unacceptable for first class. Flight attendent indicated your cleaning solution creates this problem. Seems as if this is widely known, you should be using a different product or cleaning better. Really really disappointing which simply added to the wi fi on your planes with reliably never ever works.

Snacks and included beverages were appreciated. Boarding went smoothly. Plenty of overhead bin space. Seats get very uncomfortable after a couple of hours. After waiting 10 painful minutes for my walker, a very nice Delta guest agent pushed me in a wheelchair to the gate. It was finally delivered to me after another 15 minutes . Our checked bag was on the carousel long b4 I was able to retrieve it. Fortunately it was still there but somewhere along the way the straps we used to secure it were removed and and were not reattached. Wish I had made note of the agents name.

The cabin temperature was nice and cool. The wifi was not working.

Could not get my connecting flight boarding pass until four hrs before departure! Ver annoying especially since the staff could not explain why!

First flight out and was 85 minutes delayed. Notification came out way too late

Was forced to check in my small carry on, even though I informed the crew it has very fragile items inside

First class and monitors weren’t working for mine & my husbands. Eventually fixed, but quite annoyed as we bought first class. Also, No foot rests.

Our flight was delayed several Times due to mechanical issues. Although I understand this may happen at times, it was very inconvenient and we had to book a hotel for an overnight stay. We were traveling with my 3-yo grandson and waiting at the airport from noon until 6:30pm with no reassurance that our next rescheduled flight would depart, we had to decide what’s best for him. A day later, I found out that I may be able to demand compensation if my flight is delayed more than 4 hours. I will hav to read the fine print next time.

United needs to step up their game. Delayed flight leaving Seattle, San Francisco. Older aircraft, not very comfortable.

Had to cancel first flight because Airporter Bus took over 3 hrs to get to airport which resulted in an extra $378 dollar fare . Is there anyway I can be reimbursed for initial fare since it was not my fault? Sent from my iPhone EJ Ledet

Delayed by 2.5hrs any longer and they would’ve had to honour their own policy for breaking their own rules and regs. Not cool, especially when I have an infant child that needs to stay on a routine and they get schedules.

They had three choices for snacks - but you could only have one - and they ran out of the dark chocolate before they made it all the way down the aisle... Packed flight - limited service.

They opened my checked bag and even though my lock was tsa approved, they loose my lock and left my bag just like that. Incompetent people, very upset about it. I’ll try to avoid traveling with united

We fly to Ecuador frequently. Checking in is usually a hassle because most United agents take some time before they can verify that my passport doesn't require a visa to Ecuador. This time the process was even longer due to the cyber attack. But she was really nice to us. So glad we brought plenty of snacks to supplement the 3 flights from SEA to GYE.

We had selected seats in the app that were a 2x2 format in the middle of the plane. Our seats when we got on the plane had been moved to the back rows in a 3x1 format. What’s the point of paying up for tickets that allow seat selection if the airline will just change them?

The new Airbus A231neo has neat tech but the economy seats are so tight together that I always had my shoulders against one passenger or the other. I was very miffed that Basic Economy REQUIRES check-in of bags other than your personal carry-on; if you want to offer low-cost airline prices and then add services for a fee, just let me carry on my duffel. Hell, I could have put my carry on IN the duffel and called it a day but the gate agent would not let me; I ended up paying $40 for the risk of losing my bag. Not the worst flight, but far from the best.

Terrible Initial delay for almost an hour before boarding and departing in Seattle. Then a “customary” wait on the tarmac in Newark after landing for half an hour. I call it customary because it happens almost every time I land in Newark. I do t know if it’s Newark or United airline but it’s a travesty . I use Newark because it’s closer than jfk to where I live but am strongly considering switching because of extremely poor in time performance and Condé and delay after landing

Flight attendants and crew were great! This plane was fine. It was clean and everything worked properly. Now, the gate change was not communicated. No text or information. It wasn't far with the gate change but it still changed without any communication. Not sure if this is on American or Kayakl. Also, internet was the worst. I would never have ATT. 3+hr flight and weak internet. I think I watched the commercials to get on at least 6 times. Terrible internet!

So excited very proud first of all I wanna thank kayak all updates very professional and fast alart And amazing cabin crew so nice to me they deserve big salute

Great flight - friendly and attentive team! Seats in coach were comfy, but a little cramped - but that is the case with all airlines ;)

Dreadful experience. Our flight was delayed more than 8 hours due to a maintenance issue and the assistance from rebooking was poor. I was travelling with a bad knee and needed assistance waited in one place more than 3 hours before someone came with a wheelchair. The woman next to me was a 91 year old great grandmother who had waited more than 4 hours. There were moments of support from the staff but it appeared as they were going against the direction of management. It was apathy, lack of ownership and dismissive responses with small moments of kindness and understanding typically from grey haired, female, veteran staff..

Everything was great except it became so hot on the plane I couldn’t sleep on my red eye flight. It didn’t really cool down till we started descending.

The only thing is if Wi-Fi is available after you land and taxi to the gate. It takes forever to get to the gate, and having the Wi-Fi continue would be great to bide the time at least 5 minutes before you arrive at the entrance. That is my only comment; otherwise, everything was good.

Airplane was cold. Flight attendants were rude. Phone charger did not work. No food available.

Experience was fine. Seats were cramped, and we had to wait for repairs before we could take of. Even though the door remained open, we were warned that leaving the plane could cause difficulty trying to fly out later. Staff was pleasant, and climate control was fortunately working. We had trouble at the DFW terminal, but I don't think that was AA's fault.

This flight was fine but had no time to breathe as the connection was late from Sea to ORD.. Super stressful. If we checked bags, the trip would have been very distressed.

Boarding, Seating, Flight Attendants, flight was okay. My seat was uncomfortable.
