Cabin staff were very disengaged, spoke with no eye contact, dismissive. Disappointing compared to my United experiences.

Cabin staff were very disengaged, spoke with no eye contact, dismissive. Disappointing compared to my United experiences.

awful delay, awful communication, zero updates throughout the experience of a giant delay

It was decent, there was no WiFi on the flight but the FA’s gave everyone a warning once we boarded the plane. Unfortunately it didn't give me enough time to download my entertainment content.

On Time. AA is late due to maintenance all the time.

Seats were very tight for a 17 hour flight. Baby cried for 15 out of 17 hours.

Flight attendant super rude demanding I remove my carry on baggage from overhead and place under seat. I stated I am an ADA passenger and need the leg room as the seats are very tight. That’s why I boarded early for the extra time to get situated. She said, we need the space. I replied “How can that be as only a few passengers have boarded so far? I am executive platinum status so I understand the rules and you are discriminating against ADA federal law. Please stop”. Her answer… then you should find another flight! Not ok. Addressed with senior flight attendant. So unprofessional and discriminatory.

Perfect from check in at the airport to the flight all staff were very friendly The plane was nice and clean and modern Because I’m here in the UK to visit my Dad who’s critically ill the details of me getting here were very important and nice to see staff being pleasant and professional

Both departure and return flights had mechanical delays. Their planes are antiquated resulting in a two hour flight taking almost four hours to complete.

The Charleston, WV airport was cute. Very good staff and small enough to feel comfortable. The plane had more leg room than bigger planes. Much more comfortable.

A much better flight than our previous. The flight attendant took care of us and regularly checked in to see if we needed anything. Brought us drinks prior to the departure and then a couple more times. Totally makes the difference in how you travel when the crew is checking on their passengers. Great job on this leg of our trip.
