LIT to DFW - 3 hours late; the entire plane had been boarded before they told us there was a delay due to a weather-related ground stop in Dallas. DFW to MAY - 2+ hours late due to A/C needing to be repaired after everyone had boarded, then when we finally reach the runway, the First Officer timed out and we had to taxi all the way back to the gate and wait for a new one. I arrived in New Orleans 5+ hours later than I should have. Return flights were completely cancelled; rebooked through the app to fly through CLT instead of DFW. MSY to CLT had no issues, but CLT to LIT was delayed 1.25 hrs because flight attendants had not arrived to the airport yet. At least they didn’t make us all sit on the plane to wait for them. I should have driven.

Left from gate 30 minutes before flight. Never been late to a flight ever. It says 15 minutes before explicitly on the ticket.

Even though we left CMI late, we mostly made up the time.

Horrible - they lied to me about baggage & boarding, even though I specifically spoke to their agents the day before my flight about my issue. When I showed up they did not let me board and stranded me at my airport until I bought a new flight with money I did not have to spend.

They gave my seat away although it was a connecting flight with them and the flight was a bit delayed.

this is starting to seem like an american airlines standard. delayed flights and fake apologies… getting tired of it

Both flights yesterday, experienced hard landings. Harder than I’ve ever felt before. Im hopeful there was weather involved and not pilot error. Other than the landing, the flight was quite good~

The food has never improved. It will never improve. But when I'm boarding a flight in priority boarding and I've spent 10 hours inside the security area of the airport and I get "randomly" selected for additional screening as I board the plane when the flight has already been delayed, and I work as a military contractor that has been issued visas direct from JMOD, I find it ridiculous. I would never recommend anyone to use AA on international flights. JAL is a better airline with older planes. The flight attendants on international hauls on American also have a chip on their shoulder and really dont deliver the same level of service code share partners do.

Flight boarded without pilots. Sat on plane for 3 hrs. after over an hour late boarding. Plane never took off. Had to deplane near midnight. Line for rebooking was 3 hours + long. I had to leave.

Delayd flight out of atl as always miss my conection in dfw no flight untill next day

Other than a late takeoff (not British Airways fault) and some delays with baggage, it was a terrific flight. The crew in business class was superb and the seat and accommodations clean and modern. Could not have asked for more.

Iberia subcontracted the flight out to Level (?). I would never fly Iberia/Level ever again. Old planes with no tv’s or wifi. Barely edible food. Small seats. 10/10 don’t recommend.

I paid for premium economy but BA oversold the seats and we ended up being downgraded. Not acceptable given how much we paid for the flight. We were also separated to 2 different areas so not only did we not get the service we paid for, we didn’t even get to sit together. I’m not happy at this treatment by BA because of corporate greed.

Original flight was cancelled - After waiting 2 hours for new take-off times. Then had to stand in line for 3 hours, ending at 2:30 am - to be told, " No hotel rooms anywhere in Dallas". No way for me to get any rest at DFW at that time of night.

Flight was an Iberia Flight on Level but seemed to be outsourced to a 3rd airline - Wamos. Seating pattern was different than when booked, we waited on the JETBRIDGE for 45 minutes to board, food was terrible. Movie options were limited to about 20 and very old, TV shows was limited to about 15 and equally as old. Staff was fine but definitely the "b-team". Landed about 60 minutes early and waited on the runway for 45 minutes - despite that Logan Airport in Boston recently added new gates. Mediocre experience at best.

Improve food options. Do not charge so much for checked bags. As some who paid 990 EUR fir the round trip international flight it is horrendous to pay another 140 for 1 checked bag.

My luggage never arrived in Miami; still waiting a day later.

good service from crew. Before the would have an option between cookies or nuts as snacks.. Now, there are only cookies. too bad. People who can not have sugar don't have a choice.

Service and food are good. However, main cabin with the extra cost one pays could be better. I don't see any difference with the rest of the seats in the regular category. The seats are too close to the ones in front. For short flights it is Ok, but for long ones there should be more space.

As with every airline the seats are not built for tall people.
