We were skipped when the snack cart passed and then the attendant said we weren’t . I am disabled and was in a row toward the back of the plane which was very difficult for me to navigate. Disabled people should not be forced to walk the plank.

We were skipped when the snack cart passed and then the attendant said we weren’t . I am disabled and was in a row toward the back of the plane which was very difficult for me to navigate. Disabled people should not be forced to walk the plank.

Our flight was delayed multiple times and then canceled at almost 1 in the morning. We are a family of 7, traveling with 5 young children. When the flight we were supposed to fly on finally arrived after waiting all day after an international flight into JFK we were informed our flight was in need of a copilot and once they located one we would take off. Then our flight was cancelled because the copilot was over his hours and they couldn't locate another. They knew before taking off from the previous location that the copilot would be unable to fly. They could have communicated the cancellation of the flight hours in advance. Once they cancelled and the pilot and copilot got off the flight, they joked about it. While there are understandably limits on flight time for pilots, they can still handle the situation in a professional manner. The late cancellation resulted in angry passengers that required police intervention in the airport. It also occurred so late and included other delta flights that after trying 15 different hotels, we were unable to secure a hotel room, they were all booked. No rental cars were available in the area either. We ended up staying in the airport with the 5 children. We made it home after 54 hours of travel with maybe 2 hours of sleep. Our luggage was lost and had to be claimed at the airport at our final destination. This was the worst trip I have ever taken and the worst airport I have ever spent time in. I met two individuals in the airport that were kind and helpful; Tonya Maingot Williams from the can we hel desk that worked to help get us rebooked and home, as well as provide us with care bags for our extended stay in the airport. The other individual was Danielle from Buffalo Wild Wings that was so very kind when we found a place to take our family we were traveling with to eat, all 11 of us and we were able to sit down together to enjoy a meal during such a stressful time.

On time! There were plenty of airport employees who were able to keep us moving in the right direction. The crew on the plane were professional.

Was revoked with Jet Blue due to delay from Kenya Air

WiFi didn’t work most of the time. The usb chargers would work only occasionally for 5 mins and wouldn’t charge after that. Had to keep trying repeatedly at each of the seats in the row.

The crew bent over backwards to thank us for flying and make us comfortable. The food service was quick and efficient. The Captain communicated and said goodbye and thank you as we departed. They really stood out!

my mom urmila patel needed a wheelchair which was not available on the curbside. she needed to walk almost 50 meters inside (at the risk of falling) and then had to wait in line to get a wheelchair (this is not ok). Once obtained she had to seat in it for 30-45 minutes for someone to take her in thru the checkin process (which was fairly smooth and easy). the lady who helped her with her checkin process was very courteous and helpful

This was the worse experience. They delayed our flight twice and we still had to find another flight to get home sooner which was alos delayed. Also, the flight attendant named Ginny on DL9890 leaving at 4:13pm on 3/23/26 was extremely rude.

I love Delta the flight attendants were personable and the flight arrived 1/2 earlier thanks expected. All a plus. The gate agent was a bit flustered but even with that I still had a good experience. Her supervisor assisted me.

I am still at the Airport! Delayed Delayed and Delyaed

Great. Clean. Seats comfortable. Food was free. Had new release movies.

The boarding crew was very helpful with a little special problem I had. The inflight crew - so-so.

They kept us on the tarmac for 6 hours after already delaying our flight by 2 hours. No one had any answers. They sent our gate checked stroller to baggage claim instead of giving it back at the gate.

I don’t like the music section but I believe it was a cost decision. I changed my flight last minute due to work issues and had to sit way in the back. The seats were way closer together than I would have preferred.

The flight attendant was very polite and attentive. The food was good.

Leave on time. We waited on the plane for hour hours and it was hot and smelly

Wifi was spotty. Tray table was very dirty when I sat down.

My flight from LGA was cancelled and my rebooked flight from JFK was delayed numerous times. I will now be getting home after 2am.

I would like the crew to talk LESS over the PA and specifically about credit card offers. I am trying to work, sleep, watch a movie and the PA was booming about a credit card offer. Could we go back to the days when the customer was more important than selling a credit card?

My seat tv didn’t work the whole trip. And the seat space is too small despite being seated at the front.
