The seats were comfortable and we had leg room. Great entertainment.

The flight crew where really good. Better then the crew from BNE to SFO

Safe made to destination. Late to start at GVA for icy reasons but we fought our next fly.

Miserable. They moved my seat, but canceled the next leg of my flight. I resolved the issue at my transfer, but that resulted in lost luggage that has taken days off my schedule with no resolution. Worse, they fail to interface effectively with Lufthansa, forcing me to bounce between two equally useless help desks. The apps are unable to handle the situation, the bag dropped off the tracker, and while the call centers are polite, they do not provide written information to assist with cross-airline communication.

l really enjoy very much the flight was very pleasant

It was good, although we could not get our preferred seats, we did enjoy the whole experience from Costa Rica. I still don't understand why our luggage is not the first to come out at the band.

The flight was delayed for 1:30 hours for maintenance issues. They should give more information about connecting flights. For a Business Cabin the Crew was mediocre.

Movie selection is good. Crew did not understand mileage program and were no help. Sick later. Food?

The food is terrible. The same pasta or chicken with bad taste and presentation

It was probably one of the worst flights I’ve been on. The restrooms were never cleaned or stocked. The food was very subpar, and i usually enjoy airline food, so I was disappointed. It was just all around a bad experience. The only saving grace was the flight attendants.

I got sick nothing contagious but distressing enough and the care I received on the flight was astounding.

Horrible. Both legs of my flight were delayed more than 6 hours. No compensation, no screens on the plane, and the plane was not clean.

After we'd boarded , they canceled the flight. The crew didn't even know , we just all received text messages. Then after they deplaned us , AA was just like "too bad, go F your self, we sure ain't gonna help you"

Initial flight was cancelled at the time of arrival to the airport, flight alternative requires switching from direct to flight with a layover, and the plane felt like it would split apart, it was so rattle-y.

Weather delay for 2.5 hours followed by half hour crew delay, did not have ginger ale, uncomfortable seats

It was nobody’s fault - but the plane came 4-hrs late and we were updated randomly in 20-30 mins increments which left us hostage to sit and wait expectantly. It was very long and got very late. Our plane didn’t land until nearly 1 am! Also the toilet wasn’t working. The hosts were nice enough but were clearly “about to pass out” as one told me. Lastly, there was no snack or even time for it. Just a bad experience overall.

When I'm on a 5hr 22 minute flight I expect food to be purchased. Especially when American makes a very tight connection time where u have to run to make the long flight. Chips and nuts are unacceptable and being told you should be in first class to get a meal is also unacceptable. I didn't change the flight times American Airlines did.

The boarding crew was incredibly helpful getting me on an earlier flight

Great experience. Flight boarded easily. Departed early. Smooth flight. Great arrival in DC--almost no taxing! Almost direct to gate from runway. Crew was terrific. Same cookies and beverages in main cabin. I did not use the entertainment system on this flight.

Flight delayed on both ends - have a gate ready at DCA, don't make us sit for 30min after being late to take off as well.
