The flight was canceled and very little help given at the check in desk. Everyone at the desk says: just go on the app and see how they rebooked you. I mean come on it’s embarrassing customer service.

The registration was chaotic. The kiosks didn't work for most people, and most had to do registration and receive boarding slips with a person. It took about an hour to get through he process, and I was worrying that I will be late to the flight. However, the personnel was great - courteous, professional, and was able to work through the problems.

I upgraded my seat and the service and boarding were wonderful. My flight attendant was very helpful when I experienced nausea on the flight (a first time experience). Flight arrived early which was nice. The only negative was many airlines have screens to provide some on flight entertainment, this aircraft did not. I had planned to read and listen to an audiobook on my flights, so no big deal on my part. The USB plug ins were broken on both my seat and the center seat, so I was not able to charge my phone during the flight, I will add 2 of the three USBs were broken on ride from San Diego as well. I would attribute this to the design, it is a very awkward angle to plug in, so frequent and perhaps not so gentle attempts to plug in have caused them to break.

Stay with what you are doing. Excellent service and ahead of schedule. Well done.

We had to cancel and we’re treated fairly with 100%refund quickly

There was an issue with water that led to us not having potable water onboard. They dumped the onboard water and we were two hours late taking off.

All good. Great food and entertainment when there isn’t any on a one hour flight

The flight from San Diego to San Jose gate 28A The two persons working there didn’t even turn on the display board. The display board saying to Sacramento. When I asked she was rude and showed the board . Then he realized And changed. Every one was confused because we are running late to catch that flight coming from IAD. Very irresponsible staff.

Great crew, great boarding, old B-list movies, no free meal service, child kicking my seat back all flight long, early arrival, then 40 minute, confused wait for bags.

I liked the flight attendant named Tyler. He was charismatic and genuine. I like the pilot in my second flight, he was considerate to everyone’s feelings. I liked the people I sat beside. I like the plane size. I like Alaska airlines

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

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.

Great flight, 47 passengers on a 180 seat plane. Stewardess was pleasant and cheerful.

Great experience flying Southwest. The crew was really kind and helpful, and very friendly with our toddler.

Plane late from DC to Austin 30 minutes. Crew made up much of the time enroute to San Diego.

Fine, but how to board on SW versus othrr airlines, is just lame. Goood staff though and all was solid otherwise.

Was as expected. Crowed planes. Too many carryons delaying takeoff. But the ride only took an hour and saved me a lot of time SFO is a not a great airport.

Was as expected. Crowed planes. Too many carryons delaying takeoff. But the ride only took an hour and saved me a lot of time SFO is a hell hole of an airport. It is the new LaGuardia. Everything Cobbled together. Security gates closed. Terri directional signage

I will be flying again Southwest Airlines. Friendly crew, comfortable and affordable.

The plane arrived 25 minutes late, and the Wi-Fi was slower than it usually is.

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.

Seats are much much more comfortable than United, which is what I usually fly

If I pay extra for "comfort+" I expect leg room where I can stretch my legs. I was seated with an attendant's seat blocking my feet. Knee space was fine but my feet had less room than the non-"comfort+" seats. Also, don't go cheap on food when you have flights of 3+ hours. It's insulting.

Only one side of the heafphone jack work. Crew was friendly and helpful.

Great. Flight departed early and arrived early. Deplaning and baggage claim ww were quick.

I specifically picked out right side aisle seats because my left knee sometimes needs to be stretched. But my experience this trip was that the seats were shuffled and I lost those assigned seats, resulting in me having to sit in a much less desirable position for my comfort.

They separated our seats and moved us to the back of the plane. Hundreds of dollars and thousands of miles used and this was my platinum member experience.

AC barely worked on a 50 minute flight. It was very warm the whole flight. Flight was very bumpy and hard landing.

Got on the plane and then needed to deboard the plane because they didn’t have any pilots?

The flight was canceled two hours before departure, it took over five hours to rebook us on another flight.

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

The gate was too far away for the connecting flight

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 ;)

The agents was very rude and they charged me $50 for a carry-on bag saying that it was too big and then I saw someone going on a plane with the same size bag as me

For the most part united was a good experience, how ever when they came by with the snacks and water, they completely passed by my wife and I. As we were in separate rows. On a 5 hr flight we were not offered water

Fantastic crew. Flight was delayed at last minute but we were given updates every 20 minutes and the crew was so friendly and considerate. I miss the touch screens on the back of the seats, wish they would bring that back though.

Awful. Worst airline I have ever been on. Crew were among the rudest people I have ever dealt with. United staff members were rude and disrespectful. My flight was delayed, causing me to miss a connecting flight. I understand things happen, but when staff start lying about what actually happened, that is when I have an issue. Just be honest, really it isn’t that hard. I’m being very honest with this review and I don’t find this difficult what so ever. In fact, because of United Airlines, my Christmas holiday was off to a really rocky start. As someone who has traveled across the world, it has only been United that I have had a truly awful experience.

Boarding always seems a bit chaotic. Seat spacing could leave more for leg room.

Good flight. On time. Boarding and seating was easy. Crew were really friendly, yet professional. Bathroom (by cockpit) was small but serviceable. Some the seats were showing some notable wear & tear, but were comfy. Very happy UA customer. TY! 🤛🏽💗

We arrived early and finally made it to our gate almost an hour after.

Worst airline ever! The guy weighing my bag had his foot on the metal plate and when I called him out on it, I got this stupid little smirk. La is a scam and so is Spirit Airlines. All the flight attendants looked like they hated our flight just as much as we did.

Unclear pricing; ended up being charged an extra $52 just to get onboard

Spirit is awful. Too expensive for what you get. Stop nickel and diming.

would be great to get basic water, soda at least and stop charging for carry ons

Your crew is a representation of your Standards and Values. The crew from Seattle to LAX, was very disappointing. The crew was more interested in hanging out at the lobby area. Talking, laughing loudly and eating all the snacks. They did not do regular rounds to see if customers needed anything. This was a huge disappointment. I will no longer be flying with your airlines moving forward.

- flight attendants not very friendly. - Paid for WiFi and plane didn’t have it working , never got a refund.

We got to fly on the new airplane. Much better as it’s roomier and cleaner than before. Most Importantly it’s much more comfortable. I still can’t move the seat back but the extra space made up for it. I didn’t taste the food or drinks because they charge for everything so I didn’t bother. I didn’t experience the entertainment because I downloaded my own movies on my phone. The crew was great. The flight itself was smooth . No complaints.

I was comfortable because I upgraded. I would not have been comfortable in economy. It was a short flight so there was limited food service and no inflight entertainment.

I thought since I upgraded my seat I would get some perks. Free water, free snacks. Free carry on luggage.

It’s ridiculous to pay for carry-on luggage. I also wasn’t given an option to specify I have carry on bag at time of ticket purchase. I also could not specify I have carry on luggage at time of online check-in.
