Airline reviews

I'm a larger, athletic guy (6'2", 260lbs powerlifter) and I found the seats incredibly uncomfortable with minimal leg room, especially in a window seat. Now, I full understand that being smaller may change my view but even if I was 80lbs less, my legs would be the same size and I was sandwiched between my seat and the seat in front of me.

I'm a larger, athletic guy (6'2", 260lbs powerlifter) and I found the seats incredibly uncomfortable with minimal leg room, especially in a window seat. Now, I full understand that being smaller may change my view but even if I was 80lbs less, my legs would be the same size and I was sandwiched between my seat and the seat in front of me.

The helpful attitude of the staff, and being a wheelchair passenger everyone was helpful and understanding. The trip was made comfortable by the upgraded seat which was given without my request, that was a great surprise. Thank you Delta.

Everything went well with the flight. But one of the flight attendants had on inappropriate pants. She had on an old worn out pair of sweat pants. The back seam was unrivaled and should not have been worn for work. If I had not seen her in the airport with the standard type of luggage, I certainly would not have thought she was working for Delta. Not a good look at all for representation.

Great!! I haven’t had a bad experience with them.

The plane was one hour late cause they were doing some reparations with us on the plane no mention I was in the first seat and the door was open the entire time with 8 degrees! The plane was totally dirty no mention old ! The staff was nice but no put together, the attention to details and passenger experience is missing and i always travel first !!! Is better the lounge than the plane! KLM/air France every details is taken care maybe you need a creative creator or experience client need asap was terrible and not memorable for the price that I payed very dissatisfied

Boarding super slow with people allowed to linger in aisles

We flew early evening on New Year's Eve. Our plane was less than half full... Great for the passenger experience -- not so much for the airline lol. Comfortable, spacious, smooth flight -- and early arrival!

First time travel in economy and the worst experience I ever had ! Shame on paying 600 dollars to be in a tuna can ! Service was terrible no even water no even class no even matters your flight attendants were lazy and sloppy very bad experience! After all these years traveling in first and once I try this cause I need to go to a destination for an emergency wow shame on you !

Really impressive staff at airport and on plane, especially given how busy it was

Crew was great. However the seat I had would not recline and stay put. It would spring back to upright. Hopefully they can check the seats and maintain them. Otherwise the plane is clean and the crew is very friendly.

flight delays, staff only communicating when pushed, food service lasting a grand total of 7 minutes, stuck in seat from 45mins into flight until landing

Nice flight, nice crew but no cookie or napkin with my seltzer.

The flight was canceled. Got rebooked to Chicago and when we arrived our luggage where to there. They were going to our original destination the day after. They would not deliver them to our house. We had to go pick them up.

737 Max was leaking water into the cabin through the windows. Overhead bins opened on landing. Bad bad plane.

Other than the two hour delay, it was fine. Of course they were very professional and kept us informed throughout the whole delay..

Airline did not explain reasons why flight was delayed two hours. Explanations were badly needed and rarely provided. Problem seemed to clearly be the airline’s fault and not the fault of the weather or airport.

Easy boarding in group 2. Landed 1/2 hr early. Delicious cookie snack.

Good. The wife was not working but then it got resolved.

Missed this flight due to delays from my previous flight

Easy peasy. Crew was great. Take-off and landing nice anc chill (good job by the pilot). Thank you UA!

WiFi connected but only let you go to the AA website, not even text messaging worked.

The flight was excellent, provided that we had inclement weather. We departed earlier than scheduled and arrived early. There was a little turbulence, but nothing to be worried about.

pleased with overall experienced, but seats in coach are tight.

Don't often sit in 1st class. Our experience was great.

The 2 hour delay was frustrating but our crew did a great job getting us out quickly and keeping communication especially with the people who had connecting flights

It was right on time and crew were very courteous

American always delays flight so it stressful getting the next connection

Flight was 2 1/2 hours late and information at the gate was inaccurate and inconsistent with online data.

Nothing really nondescript, the flight attendants were friendly and helpful.

I rarely vote ‘Excellent’ but this AA flight out of LGA was amazing. On time departure, early arrival, amazing crew, smooth flight, baggage came out quickly. It was the best airport/ flight experience that anyone could ask for/dream of. Highly recommend. I usually fly Delta but American Airlines really stepped up their game.

Flight was a little late taking off. Seats are too upright, no ports to charge devices, no wifi, no entertainment

They cancelled the flight then did nothing to help us rebook. It was awful - I won’t fly with them again

The truck that was refueling the plane drove away with the hose still connected to the plane and ripped part of the plane off with it

The boarding time. I was in Section 1 the lady in charge just let people in section 3 without see us. Make a line , I have to step out and ask her. We were in the line and she just take my ticket and that’s it, so if I don’t ask her she could leave us at the end! We paid more for that privilege and. She doesn’t care….

See my previous comment which is mostly about our flight from Phoenix to SFO

The check in at the airport was awful. Told I need to pay for a bag. The item was taken at screening. I went back to get my $ back and they gave me a coupon with a QR code that doesn’t work. Worst costumer service ever!!!!!

4 hour delay because they used our aircraft to fly a different segment (per the captain)

Lost baggage on my connecting flight. 24 hours later, still no update on my bags.

I had to cancel within 1hour of the reservation an they put you through hell to . no live customer service desk. I'm handy caped and they make it almost impossible to cancel. They are steeling my money. You should not have that airline on your site. Contact me and I will give you all info. Of what the are doing to me just notable treatment they are set up like that to take people

absolutely horrific. delayed flights, overbooking. over charging. nightmare service beyond words. stay away.
