I liked how it boarded fast. I do not like how the seats are just too narrow, and I’m not a big person.
6.0 GoodRobert, Oct 2026
I liked how it boarded fast. I do not like how the seats are just too narrow, and I’m not a big person.
had to check bag at gate when there was still overhead bin space. As usual the WIFI didn't really work.
Red eye from San Diego. Temperature of the cabin was way too warm and the air duct flowed very little air.
Great job Southwest! My family doesn't fly often but we felt safe the whole time.
Comfortable. Easy. No problems. Just wish they had gf options for snacks.
The charges were ridiculous for an hour flight and the turbulence was very scary.
The seats are now more narrow. I paid for front row the seats in the front are even more narrow than before.
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.
San Diego airport is brand new, spacious, airy and very smooth checkin at SW baggage drop.
No trays in our seats, we sat in first row, purchased a business class fare. Had to hold our drinks and snack in our hands. No plugs for our cell phones. Had to pay for it a drink cocktail each. Seats so uncomfortable.
The only issue is that the plane was HOT. This was not the case on my first flight so not sure why, but thankfully I had a portable fan with me. Everything else was great!
Seats were old and very uncomfortable. Coach seating is way too tight
Flight was delayed at airport with large backlog and WiFi was spotty
Flight was delayed from San Diego due to being overweight for weather conditions. We missed our connecting flight to our final destination due to the delay, as well as the connecting flight leaving before the scheduled departure time. We missed the connection within 10 - 15 minutes. We were booked on a later flight arriving 7 hours later. There were 7 passengers sharing the same originating and connecting flight.
Horrible, mismanaged ground issue resulting in a long delayed, next flight left early, waiting extra 7 hours in the airport, screen did not work
The internet on these planes stinks. Need to get starlink
Very good flight. Crew was great. No issues and we even arrived early.
Loved the crew! Sucks that we went from 1 hour and 8 minute layover to a 3 hour layover. But weather sucks like that.
Delayed flight (1hour) plus a long layover after an overnight flight with no backup plane available.
Crew was excellent. Comfort seats not as nice as other kinds of planes.
Entertainment was great. Seats were good. They did not have my pre-ordered hot food product available but did comp me something cold in place of the item.
Flight was on time, clean, etc. Despite connecting to your wi fi I was unable to use your app to watch entertainment.
The back to back mechanical delays from Denver to San Diego and then on my return flight from Denver to Great Falls it added extra time both ways
Service was professional and quick. Premium economy seat was comfortable given the class
The staff was extremely helpful and friendly at all times! They went above and beyond to get us into an earlier flight in San Diego to make our connection in SFO possible, because our original flight did actually not make it! I did so much appreciate the UA team and how they made this possible. We also didn’t have seats together on the long flight to Singapore, but they found us seats together last moment with no additional cost! Nobody sat next to us, so that we were able to sleep! Thanks to UA for improving their service and Underpricer for booking this trip! Please be careful: 1,5 hrs for transfer in San Francisco might not be enough time in the future
Over 2.5 hour maintenance delay on first morning flight with no acknowledgement, compensation or even gesture of good will. Aircraft had overnighted at airport so issue should have been addressed prior to boarding. Over 3.5 hours before first slow and deliberate beverage service.
Complimentary light meal would be appreciated. But great flight crew service on all legs
I was in first class. The outlets at my seat did not work. The plane was shabby and run down. I had prepurchsed a day subscription for internet that was not redeemable. I had to repurchase the internet for my flight and then it didn’t work anyway. Quite disappointed in what was supposed to be the launch of a great vacation.
As usual, United scheduling is completely misleading. A 54-minute layover at O’Hare is too short to make a lot of connections, especially since the flight landed “on time” but had to wait on the taxiway 15 minutes for a gate to open up. Then it takes another 10 minutes to exit the plane before one can run to another concourse to catch a connecting flight.
Flight was ok. Unfortunately it was a Boeing 737, which is a cramped / tight airplane. I prefer the Airbus as they are a more comfortable flight experience.
first leg from san diego to chicago, only had cookies for snack. 1 flavor of sparkling water chicago to washington dc had option of cookies, pretzels, or gold fish. had 2 flavors of sparkling water. 2nd flight better however the best part was there was no delays!!! Got to chicago and washington dc early. That was wonderful!!!!
I was truly shocked at how poor this flight went. The crew was not friendly during the checking process. The asked for people to gate check and were rude about it. They didn't handle my luggage with care. When I got to my seat I noticed a large section of the ceiling vent area was, no joke, TAPED TOGETHER WITH CLEAR PACKING TAPE! To add insult to injury, the back rest button was disabled on my seat and all the seats I could see. The wifi, never connected for me, despite troubleshooting it for a while. I did everything from restarting my wifi/phone to forgetting the network and restarting the app. But that didn't stop the mandatory 2 ads from playing every single time. Even the bags took over 45 mins to arrive at the carousel. Everything about this flight was a flop and I am beginning to notice that some of these events are becoming a trend. Perhaps it's time I switch loyalty programs.
Had to pay for WiFi, delayed start, and sat on the runway forever.
More space for economy, and the bathroom size is only for people with size XS
Well, true to American Airlines, both of my flights were delayed. But it’s a good thing that American is so consistently incompetent because if the first flight was delayed in the second flight was on time then I might’ve had a problem..
Was not able to do a online check-in because the American Airlines system doesn't store our visa or other passport information, allowing us to have a trouble-free check-in. We were forced to have to check-in at the counter which Changes are upgrade status given that we were not able to check in much earlier.
The entertainment package was vast and the selections were very current. Keep updating it was great.
The seat was so hard my tailbone was aching The crew was kind of a b**** because I made a joke that I didn't care if they close the door I total c*** when she was trying to f****** act like she was mad at me because I said that The flight was bumpy. Sure you didnt have control over that.
Cramped seats. FAA should make airlines have more legroom, for even short people complain
The plane was late and then sat on the runway for almost 45 minutes before taking off.
