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.

This flight was ridiculous. I had to have a connecting flight from New York to orlando Florida??? The flight left late and because it was a short flight there was no first class amenities. I had one alcohol drink. The flight crew was fine, but it sure did not feel like first class. Delta to me dropped the ball by giving me a connecting flight. By the time we got to Raleigh we would have missed the next flight. Lucky for me the flight never came so now I was stuck waiting for a later flight that came in late also.

Seat back monitors and outlets were dead and not working.

Service was good for such a short flight. Small plane but smooth flight.

The flight was delayed but we got to our final destination.

Uncomfortable seats on 14 hour flight. Mediocre food. On time and great crew.

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.

Gate crew helping to scan tickets was a little short tempered with customers. Flight crew was very friendly, welcoming , and provided excellent service on board.

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.

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..

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!

Another late flight from United. We never got the exact reason why. When we got on the plane, the staff seemed to spend a very long time just milling around in the front of the plane. I also never figured out why the door to the cockpit was open for so long prior to leaving. All in all just a poor performance again from United. There is a reason we did not choose United for the international legs of this recent trip, overall dissatisfaction.

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

Generally good but we were delayed almost two hours from the original time of purchase. The pilot claimed an internal issue then an external equipment issue that needed to be adddressed. He made up a lot of the time.

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

Amazing flight with an amazing crew. Truly impressed with how the flight was on time leaving and landed early. Bags came out quickly too. One of the best flights!! I’m

Nothing wrong on this flight but nothing special. It was oversold and they had to bump people which is always bad.

American always delays flight so it stressful getting the next connection

Pretty good. Would’ve been excellent if we would have left on time and the crew wasn’t late.

Spirit airline tries to screw you at every opportunity. Spirit wanted 65$ for an extra pound in the suitcase Made me open the suitcase at the counter to remove 1 pound. Staff very cold and rude Will never fly spirit again and will recommend same to family and friends

Overall it was a good experience. Stewards were very kind and professional. The departure and arrival times were as promised. Plane was clean.

No frills, limited comfort, no food, no entertainment, but fine

The airplane was extremely hot the air conditioner wasn’t working I

Seats horrible. No way of getting comfortable . But flight ran smoothly

Every thing was fine ,low price,easy on time ,clean, good staff, really no issues

Unfortunately not great, my flight was canceled with no notice given. I attempted to reach out to spirit airlines and have yet to receive any correspondence. I then had to book a new flight at two times the cost of the original.

The price is good but I feel that carry-on bag could be a little low and snacks prices

Pack light and enjoy the quick boarding and early departure and arrivals.
