Entertainment was great. Seats were good. They did not have my pre-ordered hot food product available but did comp me something cold in place of the item.

Premium economy was worth it. Great seats and good food.

Food was good. Clean aircraft. But why do the airlines make the seats so narrow?! Your executives should have ride in a seat so restrictive for 11 hours and see how miserable it is! When.we got to MUC they changed my boarding gate 3 times for my next flight!!!!

Good flight, even though there was a delay, still got back on time

Santa Barbara is a super small and easy airport. Breezed through rental car return, breezed through Security, ordered a coffee and muffin and to my gate in less than 30 minutes. Maybe because it was a small airport we got the oldest plane. Hardly any overhead space and absolutely zero internet. Its NFL Sunday man! That hurt.

Did not like that we couldn't complete check in on-line without providing pictures of our passports. Worry about identity theft. We had no delays and boarding was handled In an efficient manner.

Both my flight where delayed Had 25min to make it to my transfer flight

I just got back from a trip with 3 flights each way. The flights were good and we were happy with out experience. There was one steward on our first flight that was harsh and grump with passengers. It did not leave a good impression. All of the other flight crews were great on the other five flights.

They changed my flight 5 hours before it took off and changed my connecting airport messing up my entire 1st day in Japan.

United needs to figure out its Economy PLUS standards; its better than economy but that's not saying much. It seems like United stripped away all the basics for an international flight (such as In Seat entertainment) and repackaged some of them as plus. Would not fly United internationally again.

I had to buy another ticket and you haven't reimburse me for it.

AA needs to review it's policy whereby it's most tenured staff gets to pick their flights. This tends to place flight attendants with the most jaded customer service attitudes on long haul flights. Whilst I realize this is a generality I have experienced increasing levels of woefully poor customer service. One particular flight attendant on this flight was downright rude to several customers. After serving an awful meal they disappeared to their cots below deck and for the most part did not reappear until 1.5hrs before landing. A very disappointing flight.

Both directions of our trip were befuddled by massive delays, one of which led to our connecting flight being grounded mid air due to storms that we’d have missed if we were on time. The other our originating flight was delayed repeatedly until it arrived at our connecting airport later than our final leg was even supposed to have arrived. American cannot seem to manage rebooking s for a family party… both directions we had to come up with a plan to get to Boston stay overnight only one night each direction was covered by the airline -and take a bus to or from our destination. Missed an entire leg of our trip, hotel cancellation fees, expensive stay in Boston and bus ticket expenses are unlikely to be comped and the meal vouchers are worthless.

My flight was 4 hours delayed on departure at 6a causing me to miss my connection at DCA. I had to scramble to find a seat home on a later flight and instead of an exit seat, I was in row 30 on a flight getting me home 5 hours later than planned. The AA team on the ground did a fine job. AA continues to run the airline like the passengers are cargo.

The hosts were very friendly and accommodating. The food was welcomed and very decent. I would recommend!

The plane was probably full boarding was easy. We were able to check our carry-on luggage for free. It was a return flight through Philly to LA. Never saw a stewardess do a demonstration of emergency Procedures. I think my flight was pretty full

Tray table was filthy when I sat down. I needed to have someone come clean it because there was food and stains on it WiFi didn’t work after paying for in flight WiFi Food was terrible and was not filling at all Chicken was rubbery Flight attendant had an attitude, interrupted me and wasn’t able to answer basic questions about the food selection such as “does the chicken have red sauce in it”. If your flight attendants are not going to know what is in the meals so we can make an educated decision based on dietary restrictions, they shouldn’t be on the plane. My 1.5 year old niece was sleeping and dropped her binkie. I went on the ground under the chairs looking for it. It was at that time that she came up to me as I’m CLEARLY on all 4s with a flashlight and said “I need to get by”. I said one moment please I’m getting something from under the seat (while my head was literally under the seat). Her reply was “no you need to move now” and proceeded to almost push me out of the way. I looked up and all I saw was her toes under my eyes. When I looked in front of me, her private parts were inches away from my face. I then made a comment “you couldn’t waited 2 seconds?” and her response was, “no I need to use the bathroom”. I understand that and would never want to be the reason someone couldn’t get to the bathroom but I was under the seat. She could’ve gone around the other way instead of harassing me, basically placing her private parts on my head and borderline pushing me out of the way. You don’t pay (especially this much) for this deplorable experience. This was by far the worst experience I have ever had on American. I will be absolutely thinking twice and thrice about flying American Airlines again. I would rather pay more to fly delta because at least I know their WiFi will work and their flight attendants won’t have a terrible attitude for no reason, nor will they act the way this woman did. Unacceptable.

The flight was 3 hours late taking off. The lounge experience in Heathrow was terrible. No charging plugs, no table busting, and very overcrowded.

Flight was delayed after boarding and no idea when it would take off. Crew in Portland did arrange for transport to Boston for a different set of flights to my destination.

Seats are so close together. Middle seats should be discounted.
