The flight attendants were nice, but the cabin and seats were uncomfortable.

The boarding was quick, but the cabin was uncomfortable and I got stuck in the galley while the flight attendants handed out drinks after using the lavatory.

I understand it’s their right, but when two of my party missed the flight after checking in it seemed insensitive to cancel all of their subsequent flights and for us to lose the extra seating despite having paid for it @ the very least we could’ve been refunded for the checked bags that we prepaid for and never used.

Alaska Airlines has the best service of airlines I have flown the last couple years. I always choose them first.

Great. Went right to the desk and the people were helpful and kind. I was able to get my boarding pass in under 5minutes. They made sure I received the text.

The flight was delayed so we didn’t get into San Diego until almost 1 AM. Otherwise, it was lovely.

Larger seats with a bit more room would be good! Thanks for all your hard work. I think we are all feeling a bit down these days economically and your positive attitudes, both from SJC to Seattle and from Seattle to Bozeman makes more of a difference than you can see! Thank you and Merry Christmas! I hope all your financial needs are met and that very good things come your way.

I purchased a 1st class ticket and unfortunately the main flight attendant was not the best and seemed more interested in her phone than the passengers at times. Then the plane didn’t get restocked and the only snacks for this flight were pretzels. However I would like to say that the rest of the flight crew and ground crew at the airport we’re great, especially the people that wheeled me around the airport some and then the one getting me to the plane and the automated wheelchair that wheeled me through the airport.

My flight got canceled never left san diego and miss out my fam event

Flight was delayed as it always is with Alaska airlines. Particularly to smaller airports. No AC on the plane so it was miserably hot.

Flight was fine other than there was a gate change that I was not notified of. By chance I happened to check my phone and saw the change, otherwise, we would have missed our connecting flight.

Haven’t flown on SW in years. Flight was on time departing and arriving. Served vegan butter onion flavored pretzels which were bad. Coke served was in a tiny paper cup. Crew was not engaging. Felt like they were going through the motions. Old plane, tight seats and no leg room.

Check-in, Boarding and flight were smooth. All the employees and crew was very nice and funny. They gave the kids crayons and workbooks to keep them occupied which was a big win. I’ve flown Southwest many times and that’s the first time I’ve seen that and it is a great addition.

Flight was on time. Wi-fi was a little spotty/slow. Boarding and exit were efficient.

Okay, not wonderful. Short flight. Wi-fi didn't work properly. Stuck waiting for a gate to open upon arrival for 20 or so minutes.

They sent a notice that they were boarding an hour early. We had to leave the club and run to the gate. They said sorry, that came from corporate and was a mistake. They did not have enough seating because the flight before it had not taken off on time. They moved our gate and delayed it for an hour.

The boarding and seat assignment system no longer works for me, but I know it is being replaced. Otherwise, I am good with the overall experience.

The lead steward kept singing about "San Francisco" and hotel California---more annoying than humorous....needs work. Flight was smooth and on time.

Still a fan of open seating. Flight was on schedule and arrived on time. The 737 MAX is very comfortable.

Airline travel is always too cramped to really be pleasant, but the cabin crew on this flight did a pretty good job of making up for it by putting on some music during boarding and sprinkling a few funny remarks into the safety briefing and announcements, and just generally being friendly and helpful. It definitely reminded me of why I prefer the in-flight experience on Southwest!

This flight was no comparison to our prior flight. I'm thinking it all has to do with the age of the aircraft.

This flight was a first class choice and left much to be desired. Seat backs on seats were falling apart and torn. Seats actually didn't come to a "full & upright position". Pull out table was sprung. Not any significant leg room. All in all we were on an obviously older plane and felt overcharged for what we received as first class.

Flight was delayed several times. At one point, they "pulled back" 15 minutes from the delayed boarding and sent a text saying we would board sooner than previously advised. The flight then was delayed again. And when we boarded, there was an unspecified technical issue which had us waiting in the plane for about an hour.

Delta is a good airline. I've never had an issue with Delta. I'll continue to fly with them until they show me that I shouldn't.

The only thing nice I can say is the flight crew was really nice and apologetic about the situation. They shared as much information as they had and advised us on what we could do about missing connecting flights. The boarding process was so slow. The gate agent was working by herself and should have had someone working with her. It took almost an hour to board because she was trying to board a full flight of people and provide customer service to everyone who was flying standby and/or had questions. It was really chaotic. This didn't help the fact that we were delayed and folks were missing connections the longer it took.

The gate attendants and the crew were terrible. Because of high winds, they needed to carry more fuel, so they had to get volunteers to take the next flight at 6 am the next day. They did a terrible job of it - our flight ended up taking off just under 3 hours of the scheduled time. I hope to never fly Delta again.

Did not realize internet screen was hidden between seats and no info printed!!!!

2 of the seats in row 31 the entertainment system was not working, and one seat the tray table did not go all the way down. Flight arrived early and departed on time which was great.

Very good flight crew and very nice people staff were incredible especially the gate agent

Waited at the usual crowded gate at DCA where one ends up standing up because there aren't enough seats.

I understand weather is an issue, but making us chase our plane down at five scheduled gates across three terminals in an airport the size of O'Hare was unfair. They'd have probably been better off to leave gates as TBD until the inbound plane is in final approach instead of running us all over the place. Also, props to the consistently-unprepared ground crew in Richmond for once again leaving my lane parked short of the gate because they couldn't have a crew in place on time with 2 hours notice...

cabin crew was OK, food was OK, the trip from the US to Munich was actually pretty bad comfort wise. Noisy aircraft, lights never dimmed even in Business class (night flight) barely sufficient amenities for the price. I have millions of miles with United but TBH American is gaining ground and Delta has always been marginally better then United although on paper United has more longes and cheaper upgrades.

Essy to get on. The hostess gave very little pop, the plane was late getting in, and we are still waiting for our bags. This sucks. :/

Great flight. On time boarding. Smooth flight and on time arrival at EWR. The flight crew was marvelous and there was a great selection of movies on the entertainment system. Our bags were at the carousel before we got there. Another excellent flight from United.

I liked the snacks and the flight attendants were friendly.

After a delay at the gate, C3, at Ohare on Sunday, I left my Blk ski coat on the bench at the gate, lost! Please review my lob claim, thx.

Very thoughtful flight attendant offered me water immediately since I had run to make my connection.

Always wish for more healthy, gluten free options. We have to bring our own.

Having a long layover, I was very appreciative of the ability to stand by for an earlier flight. Other airlines like Delta have refused this to me in the past, just to be mean (because my ticket class wasn't high enough). United went out of their way to help me get to my destination early, which I really appreciated given that it was the third leg of a 24+ hour journey for me.

Other than a way way too cold cabinets for the entire flight, all was great

Crew were all friendly and helpful. It was a short flight so just a beverage service with a cookie. After we were boarded the plane took about 45 minutes to leave the gate but it was New Year’s Eve so not shocking there was some delay. Overall good experience and very grateful.

The boarding process needs to be fixed. The zone don't work, especially when there is hardly anyone in zones 3, 4,and 5, leaving the majority of the passengers backed up in the aisle, especially because passengers seated near the front are blocking passengers who are seated in the rear of the plane. It would also help if the size of carry on bags was more strictly enforced.

The boarding by groups is pointless. The first two groups worked fine, but almost Noone boarded in goups three thru five leaving the vast majority boarding when group six was called. It defeated the purpose of spreading out the crowd.

We loved the steward on the plane. He made the night enjoyable

The plane was late, when we did board the plane was as cold as a freezer. I was freezing the entire flight, no blankets. Lost miserable flight I’ve ever had.

3 hour weather delay followed by 1 hour (and counting) maintenance delay. UGH!

After we'd boarded , they canceled the flight. The crew didn't even know , we just all received text messages. Then after they deplaned us , AA was just like "too bad, go F your self, we sure ain't gonna help you"

After a two hour delay, my flight was CANCELLED! No pilot available. Such BS.

Amazing food, great staff, with one noticable detail missing ...but no seat entertainment in any of aircraft ...I am not a fan

I wish American Airlines would change the airline industry by loading the plane back to front instead of front to back. Planes would board so much more smoothly and quickly.
