Boarding is, as it always is… horrible. Gate lice. Slow moving zones. Too many people with carry ons

I loved having a most black flight crew during Black History Month; rather by design or accident I appreciated the representation. ❤️

This was the second flight this week with flight attendant Marcus I’m not sure if his last name is Lane or Lang but this guy is awesome. He funny, attentive and his service is 5 stars. Marcus makes business travel more enjoyable !

Although the flight left late, we arrived early. It was one of the quickest boarding and off boarding experiences I’ve had. It was kind of annoying the only drinks they had were water, coffee, and tea. The flight was very smooth, temperature was just right, and flight attendants were friendly.

Lower number on this flight so spaced out passengers. Able to enjoy more room to relax during flight. It was lovely.

Kind staff. Snacks are small but that’s the new normal.

The young man who was our flight attendant in first class was lazy and did not do his job well at all. Never offered drinks upon boarding - actually I take that back... said "are you okay with water" as if I do not want to get you anything else, only passed the snacks around once, got my drink order wrong and then never offered a second round of drinks. He was the worst I have ever seen on Delta and we fly a lot.

Great service. Great staff. Boarding was a little slow, but I think there was a service dog slowing things down.

Flight left early and arrived early. the whole trip was excellent.

Seats were really tight and the seat belts did not give enough slack.
