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

This was the second flight this week with flight attendant Marcus I’m not sure if his last name is Lane or Lang but this guy is awesome. He funny, attentive and his service is 5 stars. Marcus makes business travel more enjoyable !

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

Wonderful as usual except for other guests that were unruly and not kept in check by the Crew.

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 pilot that landed this flight in Philadelphia did an amazing job, the weather was absolutely terrible and we landed safely.

The flight was just perfect! We left a few minutes early, had a smooth flight and fortunately had landed before the terrible accident that took off from North Philadelphia airport shortly thereafter.

Staff at the gate were incredibly rude, hostile and threatening. Never fly American Airlines.

Timely boarding process, made up for lost time even after a lengthy wait for de-icing

My seat was wonky...hard and not much padding. I sat next to the Jumpseat for the flight attendant. Thoroughly enjoyed not have a third seat in that row! Flight attendants were amazing. I couldn't answer the "food quality" question as there is no food served on my short flight. I commend the pilot as I know it was super gusty when we landed. Thanks

I think I paid for an extra legroom seat and to be honest, there was not a lot of space available for my not very long legs. The flight was totally full and the staff did everything possible to meet the needs of all passengers. My only concern was for the size and spacing of my seat.

I chatted with the captain before the flight, and similarly during the welcome announcement, he warned of a turbulent flight that may impact the in-flight service. However, once at altitude, he announced that the weather changed and he immediately turned off the seatbelt sign. But it appeared the cabin crew had already decided to take off this flight. They remained seated and then just chatted in the galley. The flight was fully catered, but only first class received service.

My flight attendant was attentive! The elderly person next to me was flatulent and the flight attendant could see that I was in distress and brought me some face masks
