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

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

My seat was changed at the last minute and I was moved to the last row, right next to the bathroom despite selecting my seat well in advance. I was also made to check my carry on due to space but when I got on the plane there was significant empty overhead space. Picking up my carry on from the luggage carousel added time to my trip which had already been extended due to delay.

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.

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.

Wish movie and music choices changed more often. Mostly same from a month or two ago when I last flew.

It was good. Just that the seats could not be reclined. The people behind were not ready to let the chairs be reclined

Plane left & arrived early- 5 Crew great. Wi fi - paid for 2, only 1 worked - so so. Waste of $. Coolie was good

There was no USB plug in my section of the plane. So I could not charge my phone. Also, there was no screen to watch movie or anything like that. Wish I had known that in advance, I would’ve brought my iPad.

Made all groups except 2 check despite ample bin space. Inflight WiFi and entertainment didn’t work most of the time.

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

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

Everything was fine. Flight boarded and departed on time. Seating was spacious enough for my carryon to fit under the seat in front of me. No complaints at all. Flight even arrived early.

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!

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?

I paid for what I got which was cheap, I brought my own entertainment. I knew what to expect, so I could be prepared. If you’re flying economy, check in early like me. I have no problems with my flight, was on time, staff were friendly, and overall good experience.
