Flight was delayed, full flight and I had to change gates. Southwest flights are always late later in the day.

One major problem that was very unprofessional and uncalled for. Plane landed and we had to wait 20 minutes to get off the plane since they were waiting for someone to come to the gate to drive the jetway. Southwest couldn't have someone available and waiting for the plane to land? Is there only one person in Hobby airport who knows to drive the jetway? Was he at lunch? In the bar? Uncomfortable and uncalled for!

Southwest is kind of a slum airline. It’s gotten more expensive over the years for less and less service. I am a Southwest Chase Visa card holder and was forced to choose a seat in the 26th row in the middle seat. However my wife who is a rewards member but doesn’t hold a card or anything else, gets randomly assigned a normally paid seat in row 6! How does that work?

The seat was not comfortable. 1D. My back was sore all night and the next day.

One of the best airlines for fast boarding, on time arrivals, and top notch service!

I elected to pay for the upgrades and found very little difference

The new seating arrangement is so over priced for what you get.

Snacks are always pretzels. Why can't you also offer peanuts ?

Flight was hours late, unable to sit next to spouse, I have had so much better experiences. Substantially better, only saving grace was that it was a short flight.

An entire day of delays. Cost lots of money. Meals and a hotel.

Flight was delayed three times and we had an international connecting flight which we would’ve missed but AA manage to find us a flight that allowed us to catch and we made our international flight. However, due to the flight change, I’m in Amman, Jordan missing all 4 bags. It’s been a nightmare. Been waiting since June 17 and today is June 20th. Still without luggage. Customer service wait times are two hours and I get disconnected while waiting. I’ll update when/if my luggage arrives. Every day is costing money in a hotel in Amman. I can’t continue my trip to Palestine until the luggage arrives. Then, I will be updating my review.

Flight had mechanical issues and it was delayed 30 mins - some of us boarded and then had to deplane.

Awfully rude American worker at door when we started boarding flight. Then, walk into a blazing hot airplane with no air conditioning until twenty minutes into the flight. Free entertainment was non existent! My husband, along with the fellow passenger in our row, and I could not get entertainment to work, no WIFI! Really?? Been flying American a long time. Was very disappointed.

Leave on time. We waited on the plane for hour hours and it was hot and smelly

I’ve got 31F seat and window seat . My 2 co passengers was AA crew members and they were very rude attitude and when I was going to use bathroom their gestures was very different and awkward and the guy beside me completely occupied the hand rest and I was really uncomfortable

The gate experience at LAX was abysmal (same for the arrival experience two days prior). Despite the LAX -> SAT schedule of two flights daily, our departure gate was at a smaller hub that we had to be bussed to from Terminal 4. Fortunately, I arrived at LAX extra early and had time to spare, but if I had not known, I might have missed my flight. I looked at the LAX airport map in the AA app and there was no indication of the additional boarding process. Lastly the gate area we were bussed to was crowded with limited food and beverage options. On flight, the fight attendant was hospitable and attentive, the flight was smooth, and AA's free (and working) wifi for AA members were all on the positive side.

The flight back to Dallas was delayed, which has happened to me several times with American Airlines. There was no announcement, no update sent out, no compensation offered for the inconvenience.

As always, most AA flights that we fly are almost ALWAYS delayed and that too multiple times. Very frustrating

Boarding was smooth and seamless and the flight was without incident.

Food is what you expect on a plane. Nothing gluten free. But that is expected. Drinks, apple juice, was fine. Seat, what I expected. Fine.
