Delta is a premier airline so my expectations are most always met.

Everything was good except when we're on a 6 hour flight at dinner time and all they offer as part of the fare are little bags of junk food, it's disappointing. Bring back food service without an added price.

Left on time and arrived early this extending our 31 minute transfer. Bags made it also!

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.

Nothing unusual. It was fine. I hate having to pay extra for my seat.

The flight was so late that I had to change connecting flights, turning a five-hour trip into a fourteen-hour nightmare.

My flight consistently said it was on time and the plane didn’t arrive until after 30 minutes after take off and nothing was announced to passengers

The fight was about 2 1/2 hours delayed, but that was weather related. The flight was also overbooked. But we were in Comfort plus so the flight was fine for us.

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.
