Inoperable monitor left no entert for 9 hours. Crew was not helpful Food was awful.

The food and sitting need improvements. They were extremely bad.. If you choose to recline, there is no room for the passenger behind you. This is one of the worst sitting arrangements that I ever experience. The aircraft was not properly clean before boarding.

Had one staff that was not pleasant. Seems they are stressed with too many people to care for.

Ok. Get a different kosher caterer. The food was odd.

Lost luggage, they need a baggage service representative available all times in Atlanta

The crew was fantastic. They were there whenever we needed. The wifi didn’t work which was brutal on an 11 hour flight. The onboard entertainment was boring. Nothing of interest

We boarded but then sat there waiting on some missed connection people to get on so we sat for about 15 minutes for that. Then we sat again because the passenger manifest was wrong and they had to figure it out before we could leave. That took about another 20 minutes or so. The crew was working hard to figure it out so it’s not their fault. It ended up being a system glitch where someone was upgraded to first class while another person was also in the same seat and it just created a mess that took a little while to figure out. They literally went to every person on the plane asking their names to see who was sitting in the wrong seat. I also hate the entertainment that must be watched on your phone or tablet. Just give us setback screens. It’s so much better. Almost every Delta flight has this now and it is so nice to have them. The crew did a great job. I have no complaints from them. They were very hard working, even with the mishap and a disgruntled passenger.

Had a short delay once we boarded the aircraft in Chicago, but it was fixed in no time flat then we were on our way. The pilot was able to make up the time lost and we landed 5 minute later then schedualed . Great service

Change cabin crew assisting business class. Not taking care, ignoring requests and calls. Never had such an experience in business class.

The flight was delayed so the people from a late connecting flight was able to still make the connection.
