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

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.

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.

Tasty snacks. On-time departure and early arrival. Luggage arrived quickly at the carrousel. The only negative was a man behind us that was heavily inebriated. He was served 3 double drinks during the flight. There was no telling how much he had before the flight. He was so out of it that he spilled a drink and broke the heavy liquor glass on the floor. I don't believe he should have been served so much alcohol on a two-hour flight.
