We were 4+ hours delayed. AA is absolutely obnoxious. They just kept pushing back the time to the point where we did not get into Vegas until after midnight when we were supposed to arrive like 845pm.

My last flight on 25 Dec, it’s Christmas Day, everyone happy and very good mood. I really enjoy traveling with Americans Airlines from Miami to Minneapolis my home town after long flight from lhe to Doha then Miami. Thank you again to make my travels comfortable and relaxed. Best regards

The boarding process needs to be fixed. The zone don't work, especially when there is hardly anyone in zones 3, 4,and 5, leaving the majority of the passengers backed up in the aisle, especially because passengers seated near the front are blocking passengers who are seated in the rear of the plane. It would also help if the size of carry on bags was more strictly enforced.

I requested a low sodium meal. Reason being, I take medicine for high blood pressure and I wear compression socks on long flights to help with leg swelling. Having less sodium in meals really helps me feel better on long flights. I received my initial low sodium meal after takeoff. Just before landing, the crew came through with the meal cart and offered me what was being served. I said no thank you and then noticed my low sodium meal in the meal cart, with my name and seat assignment on it. I motioned to the crew member, but he grabbed the meal cart and proceeded to move to the rear of the aircraft. He didn’t see me or other passengers who had attempted to get this attention. He was more concerned about completing meal service since we were due to land in under 45 minutes. I pressed the call light five times from my seat to receive help, but no crew member responded to me. So, I didn’t receive a second meal, one that I requested (the low sodium option). This led me to have a migraine from only eating one meal on an 11-hour flight. This is why I’m not a fan of flying US-based airlines overseas. The crew members continue to show the absolute worst customer service experience. I would not recommend flying American for overseas flights.

WiFi didn’t work the entire flight. Very disappointing. Minimal food and options - sadly the state of current affairs. All other aspects of the flight were fine.

Great flight - friendly and attentive team! Seats in coach were comfy, but a little cramped - but that is the case with all airlines ;)
