There were many delays and cancellations due to bad thunderstorms at LGA. Despite a few hours delayed (because the airport was closed due to the storm), the flight was still schedule to leave! I was very happy about that. They did issue waivers for those who could not make the later time. Once delta got the ok to fly.. The flight left the gate very fast and we arrived and exited the plane super fast too. The process was so efficient and quick, I did not feel the waiting period. The flight attendance were so happy and positive, they made he flight very enjoyable. Great job delta!

The flight attendants were very kind and hoped to make up for the pilot’s negligence.

Boarding was weird with a lack of overhead bins and then the pilot was inconsistent with updates to safety issues. We were delayed by an hour and twenty mins and then had to wait on the tarmac for another plane to leave the gate. Feels like I wasted two hours in limbo.

The last time we flew Delta, we were underwhelmed. Our flight was delayed several hours and there was nothing exceptional about it when it did finally leave. That was 5 years ago, and there's been a lot of changes. There I'd now in-flight entertainment, reasonably comfortable seats, and everything was on time.

Virtually no food options.
