The first time I flew in the extra legroom section. It was difficult to notice a difference. I had bad luck with my neighbors. The crew was okay. Southwest has reduced the live TV options.

The first time I flew in the extra legroom section. It was difficult to notice a difference. I had bad luck with my neighbors. The crew was okay. Southwest has reduced the live TV options.

No gluten free snacks. Seats felt worn or bare bones even though it was a new 737 MAX 8.

Plane was clean and comfortable. Flight attendants and gate staff were professional, friendly and efficient. Boarding and deplaning were orderly and efficient. All in all, the typical excellent Southwest experience.

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.

This leg was much better, but we did have to have a 3 hour lay o er after coming from a very exhausting hiccup with our flight from BNA to Den

For the first time in a long time, the Wi-Fi actually worked the entire flight! The flight crew was amazing as usual.

Great flight. I didn't get a drink because I was asleep whole on the flight.

The Air hostess were very rude on my flight from Houston to Austin . Their regular communication itself felt a they are shouting at people.

It was good from LAX to Phoenix, But the connection in Phoenix to Tulsa was not that great. The staff on both flights were great. The choice of free entertainment was ok nothing to brag about. The 45 min delay because of some electrical issue wasn't great from Phoenix to Tulsa. We sat there with hardly any air, The seat I had was between windows so the side of the plane pushed in on you. My being a bigger man it then made the seating area uncomfortable. The seats on the plane had no power to connect to recharge your phone or anything. I would recommend that they should look into a slot or clamp to hold your phone to enjoy while watching the entertainment choices hands-free. Also make it possible to raise the inner seat by the window be able to raise the arm rest up to make more room for larger people to set more comfortably. I would also say other then that stop price gouging the airfare or nickel and diming everything. Not fair for people having to fly for emergencies and be paying for higher prices due to the season or holidays. Your making your money either way and the cost of flying is still going to be the same regardless if there's 100 people or 200 people.

Boarding was easy. The seats are small and fairly uncomfortable

My boarding passes were pulled from my Apple wallet and my 3 family members who were all sitting together in the same row all got put middle seats and were one of the last to board and barely were able to get our bags in the luggage bins.

Everything went smoothly from the transfer from Orlando to a quick board. Flight was not full and we were able to get underway a little early. My only critique is that in Orlando, they offered active duty service members and veterans to board ahead of their zones in the initial boarding process. They did not offer to veterans in San Diego. Both flights were comfortable

Terrible experience with an extremely obese passenger seated directly behind me - who snored and gagged so loudly, even throughout takeoff, that no one within ten rows could have gotten any rest even with earplugs! I get that this poor person has a serious health issue, and that Alaska (maybe) had no way to prepare in advance (though he did occupy two seats). Still there must be a way to take a six-hour flight without feeling like I'm next to a roaring grizzly bear.

It might not have been their fault, but there was a two hour delay due to weather. Then we boarded and were about to leave when they said there were more problems at the destination, took us back to the gate where we had to fully deplane. But then five minutes later, they said everything was fine and to get back on the plane. This was the part that pissed everybody off.

I'm tall and the seats do not have a headrest so its hard to get comfortable. Staff and checking were all great.

I was surprised by everything. The cleanliness, the punctuality, the friendliness of the crew… and the Wi-Fi! Please keep up the good work.

Good flight overall. Lots of bumps during flight but pilot kept searching for smooth air

On this flight there wer only 25 people on board. So no one in 5 rows ahead of me and noone in 7 rows behind me. So very chill.

onboard snack was pretzels, but the FA was super nice when my neighbor asked for cookies instead and also brought some for me. :)

Departing flight for our weekend trip was cancelled due to weather which meant our return flight was useless. The whole thing was difficult to get support through but Alaska did recover and was able to reimburse us for the flights yesterday. For some reason, Kayak was not kept in the loop, adding to the confusion.

The flight attendants were very friendly, efficient, and helpful. The plane was ahead of schedule, and it all went very smoothly. Thank you.

not sure why you ask about food, I n3ver get food on flights except maybe cookies or pretzels. wifi was slow and in and out most of the flight not good.

I'm not sure American is capable of on-time arrivals and departures. When you land at ORD, you almost always get held on the tarmac because your gate is still occupied. I may have missed my connection, but that ended up up being significantly delayed as well. Once again, I finally got home well after midnight.

there are no options s for snack besides cookies would ve nice to have a salty option n

Early morning flight and no food in First Class except a "salmon" box. No thank you. Was informed before take off by Captain that the plane was not serviced before we boarded in Phoenix. How does that happen? Need more frequent additions/turn over on the Entertainment. Thanks

It was the most un-special flight experience in my life.

We called Kayak for a change due to the TSA situation in Atlanta. What we got was a canceled return flight (in error) and we had to find the mistake. Not happy with Kayak who blamed it on AA.

I would have liked vegetarian and gluten free options for evening dinner time flight. I would have like a pillow on the international overnight flight . The veg wrap and oaten desert on the international flight was good

The baggage claim experience was poor. The plane crew and the AA app said that checked baggage in CLT would be at carousel 7 but the sign at Baggage Claim said carousel 1. The carousel 1 sign had the correct flight # listed above the belt. But the luggage never came. I went to an AA baggage claim office after about 1 hour and the clerk directed me to another AA room that was poorly marked, with a closed door and no obvious way to know what to do. Finally someone opened the door and my bag was inside. The clerk was totally unable to explain why.

Lack of gluten free options in food service. I have Celiac disease and it appears you no longer offer special meals for people with dietary restrictions. I am a frequent flyer traveling into and out of Omaha airport. I have noticed over the course of several months that although our flight typically arrives ahead of schedule (awesome job AA!) - we typically sit on the runway for several minutes waiting for the ground crew to get in place. Not sure if it is a ground crew issue or a gate availability issue (due to construction at this airport). Seems to be more of a ground crew being on time issue.
