2/29/2025: Tulum to DFW. Delay as usual with no explanation from AA. Three friends and I had a connecting flight from DFW to STL. We would have missed the latter without the delayed connecting flight, dashing through customs, and running through the airport. Did I mention our trip to Tulum on American was rerouted to Cancun and shuttle from Cancun to Tulum, arriving at our resort destination at midnight vs the 4 PM scheduled arrival? AA provided a lunch voucher for $12.00. The least expensive menu item was $9.99 for green beans. I will avoid traveling with AA as much as possible.

Awkward carry on process. Forced to check all carry on. No overhead space of worthiness. Left delayed, but made up the time. Crew was amicable.

Two flight changes before the scheduled flight. On the day of the flight, the flight was delayed, which caused the connecting flight to be missed. Then, I was directed to another airport (CUN) and traveled to Tulum. American gave a $12 voucher for lunch. The least expensive item on the menu at a Mexican restaurant was $9.99. Driving to Tulum was a bad auto crash, and traffic was delayed two-plus hours. The bottom line is that we should have been at the hotel at noon, but it ended up at 11:30 PM.

The boarding experience was good; $20 for wifi per flight is uncompetitive compared to Delta, Southwest, and others, and puts American lower on my list given similar pricing.

Almost everything was outstanding. First, we boarded on time and the flight crew did a great job getting everyone seated. Then the pilots took their time and care to make sure the plane was full de-iced three times as there was a bad ice storm a few hours earlier. The plane ride was smooth and comfortable and even the economy seats had decent room and comfort. Flight Attendant Lisa went above and beyond to make sure I was comfortable - she is outstanding. The only thing wrong with the flight, and it is something which needs to be addressed, is that the gate to gate time was over 6.5 hours and not one meal was served. The only thing offered to eat were two small cookies for a transcontinental flight - unacceptable. Charge me more but give me a meal for a long flight. Thankfully Lisa found something for me.

Had to wait on pilot and crew to depart and had to wait to arrive at the gate because they only had 2 crews working. Delays, delays....Planes just keep getting smaller and tighter and they nickle and dime for everything. When will an airline actually wake up and make flying more enjoyable?

We had a very pleasant flight with very comfortable seats and nice staff.

American was having a problem with their kiosks when I arrived which made the check-in and bag drop process unusually long. Additionally, they only had one person working check-in. Eventually, the kiosks were fixed and everything else went smoothly.

Airplane was cold. Flight attendants were rude. Phone charger did not work. No food available.

The flight attendants were talking the entire time on the back and I couldn’t even take a nap. Super annoying

Awful. The flight wasn't actually operated by Iberia, but by American Airlines. I was unable to get my boarding pass and as a result missed my connecting flight.

Very good service from San Jose to Madrid . Ryanair service from Madrid to Brussels 😕

I wish they could put the pre-tsa check on the tickets or global entry.

Flight from Madrid to Dakar had no onboard entertainment for a business class. Not even a single screen . That was disappointing. The WiFi only worked for the first 45 mins of the flight.

The cabin crew were great very helpful and accommodating. We had a fellow passenger throw up next to us. The flight crew did an amazing job cleaning up and reseating us. We did question as to if he should have been let on the flight as his condition was likely self imposed.

Its a bus taking you on and off the plane so if you have big luggage … more muscles needed

Bad business class. Staff totally not helping. Lights and chargers not working

Very well, except that my luggage didn’t arrive in the corresponding flight, but they brought to me the next day.

Was very unhappy with the entire process, from check in to boarding to the comfort of the flight. Did not enjoy the flight on Level.

This was such a bad experience. Iberia in Paris Orly refused to issue the boarding pass for my connecting international flight. They were evasive but said it would be dealt with in Madrid. In Madrid there was no help, no transit desk, I almost missed the flight trying to get the boarding pass and only at the gate they told me they had downgraded me. I really felt abused.
