My youngest didn't have a assigned seat until we biard6the plane.

There was no seating at the gate, no where to charge your devices, super crowded. Boarding in group F meant all luggage space was taken when it was time for me to board. The boarding crew was short with everyone and seemed irritated. The luggage space was insufficient, the seat was too small for me (6'4") and very uncomfortable trip. I was in a middle seat between a person snoring the whole trip and a person with very strong body odor. The flight crew was terse and unfriendly, seemed irritated and impatient. Yelled a lot at people with earbuds in, understandable. Finally, we arrived 10 minutes early, only to sit on the tarmac for 20 minutes and wait for a gate. Worst flight experience I've had in years.

The flight was delayed by 3 hours and 30 minutes without any explanation.

A little delay but nice flight, nice team. Thank you.

They lock the bathrooms too soon before landing! My bladder was bursting for over an hour. Then the plane had to sit on the taxiway for 1 hour. People started rushing to the bathroom. Creating a dangerous situation.

flight was late resulting in us missing our prepaid hotel shuttle

Only problem my credit card had over three pending credit card charges for luggages. I hope these charges do not post. I have already contacted my credit card companies.

Flight was late to board, then overweight. I booked a non stop flight for a reason, ended up having to re-fuel in Texas, arrived three hours late.

The groups call was not clear or loud enough so a bit of confusion there. The plan sat on the axis way for over 35 minutes ( no fault of the pilot or the crew) but nevertheless a bit tiring. The crew were friendly and greeted us with smiles. Thank you for all that you do and put up with.

My seat was comfortable. There was no TV on the airplane.

Delta flight was on time, seats were comfortable, and crew was nice.

Bathrooms dirty sinks clogged. No one seemed to clean them. Plane very old

Thank you for not flipping the plane on the run way. You guys get a 5 star rating for the flight!!!

Boarding is, as it always is… horrible. Gate lice. Slow moving zones. Too many people with carry ons

It was terrible, if they ran flights on time it would make a big difference.

Delta seems to be improving in many areas, except they are super bad with the food available. Bring back normal food service on long flights.

I actually received a notification from kayak on email but not one by text from Delta when my departure gait changed and I almost missed my flight

New boarding doesn't make sense. Filling front first is slow.

Delta flight was great from the check in all the way to arrival. However, I had a very bad experience. I requested a wheelchair and the wheelchair employee that went to pick me up from the plane in Boston to bring me to the baggage claims told me I have to pay him. I was under the impression that it was a free service and I usually give tips but the person forced me to pay and since I said no because I was upset with his demand when my daughter walked in to pick me up he demanded payment from my daughter who paid him thinking maybe now it is a charged service.

Horrible. Grateful to be alive but spent 13 hours at airport only to return back to my familys house and flight changed to next day. They tried to fix a part on plane, had no back up plane and after 10 hours , reattempted the flight and it STILL wasn't fixed. We got a meal voucher and rescheduled flight but there should be some other compensation for the 15 hours spent in airport

Everything is good except the dinner and breakfast. The sandwich is very delicious. Toilet is clean, I only use one of them. Flight attendants are very nice. 👍👍

The gate was too far away for the connecting flight

Compared with other carriers business class for an overnight was not worth the extra expense.

Seats were comfortable. It’s was so cold and very uncomfortable. I paid 2000 miles for wifi service that was choppy the whole flight. Would like to be reimbursed for my miles Food was so disappointing. Three cold and terrible meals for $3000 round trip. This needs to be better.

Easy to board. Flight was super crowded though so I didn't sleep well on that cross country red-eye flight. The aisles seem ot have gotten narrower and the seat smaller whn luggage and people are getting bigger so it would be AWESOME to have more space and breathing room in general ;)

Pilot Erika DeLong made us feel safe and at ease in a frankly scary time to be flying. Her warm smile and greeting and excellent command of the aircraft in foggy bumpy weather helped us all to calm our nerves and get us home safely.

Plenty of room for me and the cat in Premium Economy. Seat was comfortable. Boarding was a breeze. The lady at the special check-in desk was great, super helpful and professional.

Smooth flight. As always dinner could have been more generous. Breakfast was great.

AWFUL. I have had the experience of traveling with many airlines across the world, and hands down United Airlines is the worst. Not one flight was on time, and I don’t think I met one crew member or staff member who wasn’t rude.

Old and out of date plane, it seem like every time I fly with united there’s and issue. We were delayed,

Excellent from start to finish. All staff members were amazing!

Excellent. Although they used to greet me as a mosaic member and provide a free drink, early boarding helps me to keep coming back to JetBlue.

Cancelled flight with no specific instructions to get a boarding pass for another flight. The whole flight of people were in line for an hour because there was only 1 person to help at the desk. This was unusual for JetBlue.

It was too hot in the cabin. The AC did not help.

Except for the 28 minute delay leaving and the earlier reschedule to a later takeoff time the flight was good.

Loved the leg room and tvs screens on the seats and free WiFi. Wish the price was lower and could save by rebooking

No music app working: no economy meal on five hour flight; hour on tarmac at the end waiting for a gate. Flight itself was smooth and easy.

It took 1-1/2 hours to get our luggage after we landed. That to me is unacceptable

The flight was delayed for 4 hours. Once onboard the crew was wonderful.

Overall was excellent. Will definitely us JetBlue in the future.

Very helpful ground crew after an earlier flight delay and being rebooked on a different flight.

British Airways staff are very polite and willing to help.

The plane was late and then sat on the runway for almost 45 minutes before taking off.

We kept being told that the flight was full and that all overhead compartments were full and therefore had to check in our hand luggage. We were some of the last people to board and noticed that there was still sufficient space in the overhead compartments. We were obliged to check in hand luggage when there was space and so had to wait at luggage retrieval which took a while to then noticed damage to our luggage - not a great experience!

Worst seats I’ve ever had !!! The seats were very narrow and uncomfortable and misaligned with the seats in front of mine leading to bottom of the seat in front of mine pressing on my legs for 15.5 hours !

This was an overnight flight. There was no meal service in first class, just a simple snack basket was offered along with beverages. There should have been some type of continental breakfast prior to arrival in PHL. As an Executive Platinum American Airlines Advantage member, I received no name recognition from the first class flight attendant. When disembarking at PHL, the flight attendants were more interested in their cell phones than saying "thank you" to the passengers as they disembarked.

The flight was quick and to the point. The crew just did their job w/o excessive talking and everything was just perfect.

Awkward carry on process. Forced to check all carry on. No overhead space of worthiness. Left delayed, but made up the time. Crew was amicable.

Amazingly comfy flight - I had upgraded for a reasonable price and it was worth it. The food also was good.

Had to wait on pilot and crew to depart and had to wait to arrive at the gate because they only had 2 crews working. Delays, delays....Planes just keep getting smaller and tighter and they nickle and dime for everything. When will an airline actually wake up and make flying more enjoyable?
