Round trip flight to Canada and back to the US was smooth and efficient.

It was beautiful easy and smooth experience. Thank you. Will definitely get Delta for my next travel.

After I checked in, I realized we had no seat assignment. It said they would be assigned at the gate. This was really frustrating because I usually use a lounge before flights, but I couldn't because I had to be at the gate to ensure we got our seat assignments. The gate agent arrived an hour before the flight left. I was the first one up to ask about seat assignments. She told us to wait for names to be called. Dozens of other passengers were paged, but we were not. Finally, I asked my husband to ask. He went up and was also told to wait. About 10 minutes later, they called for boarding. We still had not been told our seats. We went back to the desk and they were in a panic, saying we actually weren't on that flight. Then they made an announcement telling the stand by passengers to not board (in case we needed their seats). It was so stressful and unprofessional. Finally they gave us our seats. I have no idea what happened and why the two desk agents seemed to have conflicting ideas about our seats, whether we were on that flight etc.

Very dissatisfied with the fact that I had upgraded to first class for the second part of my trip only to find out that the lounge was still not available to me, as well as not having any food or drink service on the flight due to weather, so I lost out more than what I paid for.

Overall it was not that bad! The delay on the second leg to Indianapolis , was really unexpected!!

It was very good. Our flight was delayed and we as a result missed our connecting flight but rescheduled to the next day. The Need Help staff was so great and offered us compensation that was beyond satisfactory.

Excellent. No issue and it was on time and arrived early, the best!

The flight was oversold and they kept on announcing they were looking for a volunteer to give away their seat, but the announcement has to be louder and clear @ gate 88 and also must precise. Additionally, the departure time kept on changing. But overall it was fine since it was a short flight.

Among the poorest flights I’ve had with Delta in a while. Entertainment system failed completely on a 7.5 hr flight. Crew seemed distracted and not the normal friendly crew. Flight overbooked it seemed… very crowded.

It was a Red-Eye flight so was not comfortable enough to sleep, but seat was as expected. Crew was great and in-flight entertainment was excellent. Flight was smooth
