Everything was on time and service on the flight was great!

The travel company that you have on your site did me so wrong. I don’t know how it happened, but they put my son‘s name on my plane ticket flying to Vietnam. Along with his birthday. They would not have let me fly from Fort Myers to Ho Chi Minh City. I don’t think that I can ever use your service again. I typed my information into the browser along with my passport number and four days before I’m leaving I have to quickly search another ticket to fly out here.

It’s always a great time flying with united airlines.

Good flight. Efficient boarding and competent flight crew. No problems until we arrived at our destination gate. We were early so there was an aircraft at the gate that had to move before we could pull in. Then, due to the type of aircraft we flew, the cabin door could not be opened until some luggage from the cargo bay was offloaded to preserve center of gravity characteristics. So, that further delayed deplaning. Despite being 20 minutes early on landing, we ended up being 5 to 10 minutes late after all the delays.

This trip did not start off well. The inbound flight was delayed about 20 minutes. Then, after initial onboarding, the passengers had to deplane due to a mechanical problem. That took about 30 minutes to fix and be cleared. Then, reboarding was chaotic. It took a long time to sort passengers and two passengers on standby were ticketed but there was no seat. So, they had to deplane. One of the flight crew was trying to help passengers figure out a place to put their carry-on bags and that took more time. In the end, our scheduled 10:30 am departure did not actually take off until about 12:05 pm CST. The flight itself was long but we got to Houston. Some passengers missed their connecting flights and had to rebook. Not the best of flights I've had.

Complimentary light meal would be appreciated. But great flight crew service on all legs

Everything was great except for the boarding process. Everyone is lining up all at the same time and it’s hard to tell between the groups as they are way too large.

Very old flight - time to retire it for newer airplanes

2+ hours delayed Outlet in row 12 did not work Tv monitors did not work Lights kept off the entire flight for at 5pm-7pm flight

Do not like the size of the overhead bin. I think staff should monitor the size of suitcases that are being carried on by passengers to ensure they meet the size requirement.

They put me on an earlier and I got home sooner

Not good. One of my luggage is missing. And until now they can’t find it

Jill was the flight attendant in first class she was fabulous!! Best flight attendant I have had in years.!! And I fly every other week. Other can learn from her!!

The business steward was absolutely amazing! Smiles and kindness! Wish all AA flights are like this one!

Delay after delay with little communication then AA lost my luggage and at airport would not assist just said scan this QR code to track your luggage and submit a claim. However QR code provided did not work so have to go back to airport

Where do I start!! I was delayed with my flight from Dallas to Tampa. On the way back from Tampa to Dallas the flight was delayed over 4 hours+. I was put on another flight that was also delayed but not as long. Traveling on American Airlines is becoming exhausing.

Never going to fly your airline again if it can be avoided.

Dloght delayed by 2.5 hrs . Common theme in my last four american floghts

The flight attendants and the service is getting worse by the day.

They are rarely on time! Very hard to plan your travels when flights or connections keep getting delayed.
