Flight was awfully bumpy and landing was a bit jolting. I was in the restroom when snacks and drinks were served and was not asked if i wanted any. I had to ask for water finally.

Flight was awfully bumpy and landing was a bit jolting. I was in the restroom when snacks and drinks were served and was not asked if i wanted any. I had to ask for water finally.

Wi Fi was horrible kept cutting out the whole time and too expensive

I really like open seating. I hate that I've heard this is going away. This is one of the unique things that makes Southwest my goto choice.

Boarding was a little late, but made up for it. It was quick to taxi to the runway, since it's a smallish airport.

Excellent! Only question is how we check in at exactly 24 hours in advance and end up at the end of the B boarding group

Multiple delays and gate changes. Arrived at final destination 6 hours late. All rental cars had been taken.

Employees were kind and funny, as always! Flight was late but no announcements were made for people with tight connections to help them transition quickly. No service due to turbulence.

It was 2 hours 45 minutes late, for no apparently clear reason.

I recently flew Southwest from San Jose to Honolulu. I was very impressed with the flight crew, especially the flight attendant in charge of the front of the plane. She came through the aisle at least five times for drinks and water, and two times for snacks. I have not seen such service since I flew first class. Also, for the first time, they gave us the correct baggage claim number, and the luggage came out quickly. I can't wait for Southwest to have assigned seating! I absolutely hate the Cattle Call boarding procedure and the mad dash to get seats and overhead bins. However, the boarding was efficient.

Crew was great flight was great baggage claim was a failure. It took over 1 hour for bags to arrive. Poor communication poor effort when I spoke to the supervisor about the delay

Small plane, so no entertainment. Hour delay! Nobody explained wht the delay was all about.

I wasn’t happy with the hour delay from Dallas to McAllen, but that is the nature of travel. I don’t like to fly in general because of all of the problems all the time.

It went up and down at the right time and place. I’m happy with that outcome.

Staff at the gate were incredibly rude, hostile and threatening. Never fly American Airlines.

Would have been good to have a meal since it was a 5.5 hour flight

Same problems with delays in Dallas. This was weather related and due to the incoming flight being delayed. This was the flight that was delayed due to a missing flashlight which turned out not to be missing.

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.

I had a horrible experience from the time I dropped off my bags until the time I landed. The staff taking the bags at the check-in counter prior to security, forced me to check my baby stroller, even though it weighed less than 20 pounds. their excuse was that the wheels were too big. I have never had an issue gate checking this exact same stroller in the past either on American or on any other airline. when I asked for the agent to show me the rule about the size of the wheels on strollers, they told me to look it up on the AA website. I did so, and did not find any indication that wheel size was a problem for gate checking strollers. The only limitation would be the weight of the stroller which mine was below. I was left with a one-year-old child and all of my carry-on luggage, diaper bag, and the like to walk around the airport without the assistance of a stroller and had the same issue when I exited the plane and had to go all the way to baggage claim without a stroller. In addition, while on the airplane, I was told I can only get one bag of cookies as a snack, even though I was with a child. Apparently my child and I were supposed to share a cookie. While this latter issue is a minor one, it is just another example of the absolutely horrible customer service that American Airlines provides. In addition, the 737 aircraft that I was on was extremely hot and the air vents above the seat were so far away from the aisle and middle seats that it was comical. I could barely reach the air vent to adjust it. I had to ask the person in the window seat to do it for me. The whole experience was just a nightmare.

We boarded after several delays due to mechanical failure and a gate change. The seat cushion in the exit row was very compressed and offered no cushion, making the four-hour journey reasonably uncomfortable. The WiFi worked for a few people, but for most, it did not, and you cannot get entertainment unless you can connect—American Airlines flights do not have seatback screens, and you must use your mobile phone.

Terrible. Internet/kiosk glitch prevented baggage checkin. Line at ticket co in Ter was under serviced and did not move. Agents did not call for flight but rather allowed time to pass. Then told each person as they reached the front if line that it was too late to check bags so they’d have to rebook flights. At least 15 people missed the flight as a result of this incompetence.
