I liked that it was on time, however, the food was not good.

I liked that it was on time, however, the food was not good.

Fine. The issues I had were associated with luggage being delayed from Turkey to Tanzania

They were fast and I like how they used to entertainment system to play video about the safety.

No meal service to the back of the plane as it started late or was too slow to get it out before it was time to land.

Terrible, if possible won't be flying again anytime soon!

Efficient boarding and early departure. Very smooth flight. Early arrival in ATL. Great flight.

We purchase first class seats for the first time for multiples of standard economy ticket. There was no access to the club lounge and no priority boarding. The meal and the service once on the plane were superior and the seat was nicer, but not worth the price difference. I will be happy to seat in economy and spend the difference on more travel.

In general, flight attendants were not very welcoming. Because of delays in departure and luggage handling, we missed our connecting flight. Offered a later flight on standby but available seats were then taken by 4 or 5 airline crew so slept at airport and got home next day. I am a frequent traveler, and this experience was the worst.

Wonderful in-seat entertainment with seatback screens and huge selection of quality movies. The ability to bluetooth connect headphones was amazing.

Smooth and easy boarding, comfortable for the entire 5 hour flight, and the seat back entertainment was great! I appreciated all the features, from location info and maps, movies, the ability to connect with Bluetooth headphones, and good selection of movies. Food was good, normal airline snacks (I didn’t purchase anything)

I have never been assaulted they way I was today in Charlotte - shame on American

One of our group members was struggling to walk. In Charlotte we asked for a wheelchair and she was accompanied by Desmond. I was impressed by his patience and attention. In Boston she received the same service. I didn’t get the name of the helper but she went above and beyond in assisting us. A great AA service

Delayed 24 hours. Should have called it much earlier They provided quality accommodations, food vouchers etc. FINALLY The issues started at 8 AM and they cancelled the flight at 11:30 PM, with no plans for a new flight.

Better snacks but flight and crew were amazing on this flight

Found that the plane used for this short flight is smaller and therefore the seats are really squeezed tight.

It was the most un-special flight experience in my life.

Plane was super cold. No entertainment unless you were with mileage program Getting off the plane was super slow

Flight was on-time, boarding was flawless and the crew was friendly.

The staff are very, very professional. It's what flying should feel like.

Flight boarded from Gate 159B, the farthest gate in the LAX Bradley Terminal. While the flight operated on time, the first class cabin attendant made no recognition of my being an Advantage Executive Platinum member.
