The flight used a B767 with a very old interior from before 2014. The entertainment system did not work at all during the flight despite attempts to reset the system. It was like they flew this route just to be competitive.

The flight used a B767 with a very old interior from before 2014. The entertainment system did not work at all during the flight despite attempts to reset the system. It was like they flew this route just to be competitive.

Crew blocked exits to front of ship with galley carts. Also split five person family apart on international flight without fixing.

They changed planes and the new plane couldn’t carry enough fuel to fly across the country so we had to stop in Kansas City to refuel. Flight was delayed .

Flight was too crowded and seats are too small, especially since passengrs are getting larger. Having a middle seat is ALWAYS tough! Woman on my left was large & kept creeping in to my space. Flight personnel were great! Have more savory rather than sweet snacks please.

Flight was crowded and the woman sitting on my left was large & kept crouching in to my space. You need bigger seats or smaller passengers to fit into the seats you DO have! Snack were OK. Would appreciate if airlines had more savory rather than sweet snacks, thank you!

Delayed flight (1hour) plus a long layover after an overnight flight with no backup plane available.

We were delayed, which I think had to do with air traffic control. Otherwise, everything was great.

The boarding process needs to be refined. Sometimes the gate crew calls out the zones and then flip to showing the.zones boarding on the gate monitor display. So, unless you are huddled around the gate lanes watching the monitor, you could miss your boarding zone. Suggest the zones be announced each time a new zone is allowed to board.

The boarding process needs to be refined. Sometimes the gate crew call out the boarding zone, and then flip to the monitor to show which zones are boarding. So unless everyone is gathered around to see the monitor there is usually confusion as wi which zones are boarding.

On time flight. Seat comfort could be better in the Comfort section.

the trip to madrid was uncomfortable with my legs touching the seat in front of me

Very crowded flight but what can you expect these days?? Crew was accommodating.

Small outdated plane from Philly to Des Moines with very uncomfortable seats. The plane was old, so we had mechanical issues that delayed us for 3 hours with very little communication. It was a very unpleasant experience and I will try to never fly AA again.

The seats in economy were appeared to be quite thin and lack sufficient cushioning to be comfortable. Perhaps it was my seating position but the plane seemed notably load.

Internet was a bit expensive and did not work ask that week otherwise a good flight

They don't make it easy or promote their food options. Dirty plane. Delayed.

International baggage recheck process in Philadelphia was a disaster. Waited 1 hour and 45 minutes to receive our bags. Waited 15 minutes to recheck bags, flight notification boards were blank so we asked an AA representative for our connecting gate and we were directed to the wrong terminal and gate. Our connection window was over 3 hours and we made our flight by 5 minutes. We pulled away from the gate and sat on the runway for 1 1/2 hours. 1 of our 4 bags didn’t make it to Phoenix. The mobile app for lost baggage didn’t work, the AA rep had to manually fix.

I miss my flight and they could not rebook me that day because the other flight was full, and for the next day I had to pay a whole new fee again which I think is unprofessional

The flight had a delay that made me being in a real rush to take the second flight. The delay was almost for 2 hours. They moved us from gate to gate in 4 times. Once I arrived to Philadelphia, I got to run thorough all the airport, as the train was already closed by that time. So I got sick with asthma for all the running I had to do. And I was the last one to board, when it was almost closed. So irresponsable with the people

The plane was probably full boarding was easy. We were able to check our carry-on luggage for free. It was a return flight through Philly to LA. Never saw a stewardess do a demonstration of emergency Procedures. I think my flight was pretty full

Seats are not very comfortable, maybe a little more padding for a 2hr plus flight

Vegas is such a quick flight that amenities aren’t the important part, in my opinion. Just get me there efficiently and safely, and that’s exactly what they did!

The flight was severely delayed due to the missing flight attendants.

Absolutely horrible. Usually pay $40-$50 to check luggage in. I tried to check my suitcase in and the price is raised to $70. That's ridiculously greedy c'mon. I had to leave my suitcase with all my clothes and hygiene products and repurchase once i landed in Atlanta. You guys make it really stressful to travel. Don't even want to travel anymore.

They cancelled the flight 3 hours prior departure. Had to spend $400 for a ne way flight with Delta Airlines! Spirit Airlines are not serios!

My luggage didn’t arrive at LAX, so that wasn’t a good experience.

Terrible seat, no in flight entertainment. No complimentary food or drinks. Seats really hurt my back after flying spirit for the day.

Plastic seat really hurt my back. Cannot even recline on the flight. Very hard to sleep on the plane due to terrible seats . Food and drinks were expensive and not very good. There were like 2 open exit rows behind me. My isle was full so I asked flight attendants if I could sit there. They told me it was a safety issue??? I think it more unsafe to have no one sitting there. In case of emergency, you’d want someone there to help.

Over SOLD flight. It does not matter that you were able to check in 24 Hours before and confirm your flight. At the airport, the company SPIRIT rep wanted to remove people who pay for lower fares.

The delays and the lack of communication and organization within the airport itself for Staffing this flight and coordinating the paper log necessary to depart was ridiculous and deplorable
