My youngest didn't have a assigned seat until we biard6the plane.

Booked a premium seats weeks ago and got an email the night before that id instead be seated in the cabin. Only reason I booked this overnight flight was for the better seating. All they are doing to compensate is giving a $29 coupon to use on another flight. I won’t be booking this airline again.

It was all great all around. Will travel with Alaska next trip.

I got the last seat on the plane, in the back in the corner against the window, and I paid a competitive price for my ticket several weeks before the flight.

Everything was good. However, the selections of movies and TV shows were boring and unexciting. It was disappointing.

Long delay before boarding. By the time I was informed of the delay I was already at the gate.

There was no seating at the gate, no where to charge your devices, super crowded. Boarding in group F meant all luggage space was taken when it was time for me to board. The boarding crew was short with everyone and seemed irritated. The luggage space was insufficient, the seat was too small for me (6'4") and very uncomfortable trip. I was in a middle seat between a person snoring the whole trip and a person with very strong body odor. The flight crew was terse and unfriendly, seemed irritated and impatient. Yelled a lot at people with earbuds in, understandable. Finally, we arrived 10 minutes early, only to sit on the tarmac for 20 minutes and wait for a gate. Worst flight experience I've had in years.

I made a mistake. Read what I wrote in the flight from Dulles to SEA. The negative experience was from SEA to BOI. Total garbage. Wont do it again.

Flight 351 SEA to BOI was terrible. We got to cruising altitude and I needed to use the restroom but the fasten seatbelt sign never came off. There was no turbulence and I'd felt the plane level off so I stood up to use the restroom about 15 minutes after we leveled off. The stewardess went over the intercom and said I needed to be seated because the captain hadn't turned off the fasten seatbelt sign....Which... Fair.... But not five minutes later she went and used the bathroom. Felt very unprofessional to leave a paying customer with a burning urethra for the entire flight and bark at them to sit down and still use the bathroom yourself. They never did turn off the seatbelt sign.

For longer trips, snacks are puny, boring and don’t have ANY nutritional value.

It is southwest seat was ok. Not the most comfortable seat

I’ve always loved Southwest. No issues at all. I was flying standby and the gate agent was extremely friendly and helpful. Boarding was smooth and I was able to get a window seat in the emergency exit row. Crew was fantastic! They were very professional and accommodating. We had to divert from our destination due to weather but the flight crew kept everyone at ease and informed us of all pertinent information. Excellent flight

The price of the tickets isn't matching the flight experience. No matter how long the flight is, you're only getting pretzels. The flight attendants looked unkept and over it.

Plz don't take away free bags and free seating

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

I would have liked to arrive on time - not 5 hours late!

After a 3 hour layover in Denver my flight was delayed over 5 hours! No explanation; no assistance; no offer to provide compensation; no one at Southwest was willing to offer any assistance. 8 hours in the Denver airport - ridiculous!

It was a perfect flight in all aspects! Both legs!

Only one drink pass through the cabin for a 4 hour flight. Quite rough and bumpy landing.

Boarding process, crew were good. But the seats were so uncomfortable that was all I could focus on. I literally had to sit forward so that all 3 of us could fit in row. I will try to avoid Southwest in the future for any flights over 60 minutes.

Delta is my preferred airline. I've traveled with them for years. On time in most cases, good communication, easy to use app. Most planes are pretty nice. I was on a CRJ 700/900 however, which was pretty badly aged inside and needed a refresh. No infotainment, unreliable wifi, best to download before boarding or bring a book. Food choices are really just snacks on this flight, nice variety but about what you'd expect. Great staff and prompt in departure and early arrival too. Overall quite satisfied.

Crew was friendly Love the entertainment in the seat head rest.

Delta flight was on time, seats were comfortable, and crew was nice.

This had nothing to do with Delta… The flights were on time and flawless. The service was excellent. We purchased seats in (aisle/middle) comfort plus since this was a cross country flight. Unfortunately, the woman seated at the window was 300+ pounds and, as might be expected, covered up about a third of the middle seat also. there was absolutely nothing that Delta could have done about that… I just don’t know what the answer should be. If you purchase a seat, you should should be able to use the entire seat and not just the portion that someone else is not sitting/oozing in. Disappointing…there should be something that could be done….I'm just not sure what solution could be.

Delayed take-off. Very small plane so very scary with lots of bumps during the flight. Would never fly Delta on short flights in small 80 seaters plane again! Felt relieved when landed.

The worst part was I was NOT allowed in the lounge even though I was holding a first class ticket and have a premium American Express card. I have flown Business or First Class with many airlines. Delta is the ONLY one who does not extend this courtesy to anyone except people who hold the very expensive American Express card. As a result, I won’t fly Delta if I have any other choice.

A little bumpy ride . No food was being provided due the the turbulence. That was ok it was a short flight to my standards.

Simply outstanding. Their new lounge for Delta One customers is a cut above the rest.

The Dekta Rep that checked us in was great. She's very personable, pleasant, and can tell she enjoys her job.

The plane was old with small storage areas that had problems closing/latching and not enough storage for everyone, and worn, damaged seats. Service was great but feel a little unsafe on such well used planes.

A bit rush for transit. Food and entertainment are not available

Smooth boarding process. Early departure, smooth flight, early arrival. The entertainment package has very good recent movie options. The flight crew were friendly and professional.

My flight was scheduled for about 6:05 departure. There were 11 gate changes from 4-7pm and the flight was 3 hours delayed due to operational issues. The plane taxied around the airport for about half an hour before stopping to be de-iced. It would have been nice if we were alerted of the plan to de-ice prior to the 30 minute drive around the airport. The flight attendant was friendly, which was the only redeeming thing about this flight. As a former flight attendant for United, I was extremely disappointed.

Delays took 2hours and thirty minutes making me miss my connecting flight and make me sit in the Chicago airport for 9 hours

Had a short delay once we boarded the aircraft in Chicago, but it was fixed in no time flat then we were on our way. The pilot was able to make up the time lost and we landed 5 minute later then schedualed . Great service

Our seats were all the way in back of the plane,

The seats on this flight were almost roomy enough to be the basic amount needed for human existence. I think my favorite part of this flight was it landed at an A gate, which was the most palatial part of Sea-Tac I've ever seen - a massive improvement from the S gates.

The seats on this flight were almost roomy enough to be the basic amount needed for human existence.

The flight attendants in First Class were mediocre at best. They did not take our tray away until we were about to land and only did so when I press the call button. The United person at the United Club was asked to get us our boarding pass since we missed the flight due in Chicago. She argued that we did not have seats on the flight given to us in Moline. Furthermore, she was adamant that we did not have a First Class ticket. After I spent much time with her trying to show we were correct, she reluctantly agreed. She was probably the most incompetent ticketing person I have ever met and I have traveled 3 million miles on United plus many additional miles with other carriers. United has definitely deteriorated in more than on way.

Short flight - no food understandable. Flight was delayed for over an hour. Overall, it was good.

I have long legs, my foot was out in the aisle and when a flight attendant came walking by and I didn't notice, instead of saying "excuse me" or anything like that, she kicked my foot. Extremely rude

Excellent! The gate agents were kind enough to rebook me on an earlier flight saving me from a 6 hour layover. Even my luggage made it despite the fact that the connection was technically too narrow. The flight itself was very comfortable, roomy, and clean. Plenty of space for my carryon items with plugs to charge my phone. After a long international flight of 14 hours, this was an excellent way to end my travels!

Great experience. Flight boarded easily. Departed early. Smooth flight. Great arrival in DC--almost no taxing! Almost direct to gate from runway. Crew was terrific. Same cookies and beverages in main cabin. I did not use the entertainment system on this flight.

Most of the delay was due to weather which is not what was at issue here. One delay was due to a missing flashlight and in the end the flashlight was actually found on the plane. The entertainment system is very limited. Live TV options offer only a few channels that are not very appealing. Boarding and deplaning are always difficult. It just takes too much time to get on and off the plane. On the plus side, I missed my connecting flight, but was easily able to book a later flight from the app while enroute.

You were more on time than United. I'm so over united delays.

The meals were mediocre and the alcohol selection was poor. I enjoyed the selection of movies and other entertainment.

I chatted with the captain before the flight, and similarly during the welcome announcement, he warned of a turbulent flight that may impact the in-flight service. However, once at altitude, he announced that the weather changed and he immediately turned off the seatbelt sign. But it appeared the cabin crew had already decided to take off this flight. They remained seated and then just chatted in the galley. The flight was fully catered, but only first class received service.

My flight attendant was attentive! The elderly person next to me was flatulent and the flight attendant could see that I was in distress and brought me some face masks

My boarding pass wouldn't pull up in the app very easily and had to really dig through my email. That caused a delay in TSA..

I had a TERRIBLE experience with the AA crew. I believe it was disability-related. It’s unlikely I will fly AA again.
