After a 5 hour delay waiting at the gate (3 delays adding up) with no clear reason provided, we finally boarded flew 3/4 of the way to Toronto then were turned back to New York. As we neared New York, the pilot declared that it was his fault, something to do with timing and him not being allowed into the country???? How could the airline let his happen? They had hours to prepare and make sure they had a crew available for the flight! We ended up in Toronto a day late with no sleep.

Rode in a smaller plane and short trip meant no snacks, no free wifi or tv. It was only 30min flight so honestly wasn’t a big deal to lack these items.

Overall, terrible. Flight from SFO was delayed due to “air traffic control issues”, and we were all mislead about connecting flights. Told “you have 20 minutes to catch your connection”. Reality was 5. We got to watch the plane sit at the bridge. Won’t fly Delta with a connection again.

We were forced to wait nearly 50 additional minutes before leaving the terminal.

I appreciated friendly service from check-in, to boarding, to in-flight amenities! Attendants were accommodating and helpful. Thank you! Elaine

Delta was really good about being transparent with why we were delayed it’s just that’s the plane was really old and outdated and a lot of the comfort and amenities we know Delta to have did not shine through

Forced to check my bag which fit in carry on, boarded and then sat for over an hour waiting to take off with no explanation.

Did not get a vegetarian option in 1st class and the video was not working.

My sister and I paid to have our seats and have them next to each other. I heard one of the employees say to the other one that you shouldn’t have given away reserved seats away to other passengers, and so I guess that is what happened because I got the last most uncomfortable seat in the plane even though I paid to sit in the middle of the plane with my sister. Terrible Experience !!

We checked one bag. That was fast and the agent was fast and super nice. At the gate, boarding was fast and efficient. Flight was uneventful which was great because it was early in the morning and most folks were sleeping. Landing was great. Delta does a really good job of making the flying experience better all around considering you are sitting in such a small space on a plane for several hours.
