The tray table was broken and the food was terrible.

The gentleman at the gate I think his name is RIE was exceptional

While they turned off most cabin lights to allow people to sleep, I was bothered by how bright the side lights still were. It was still quite bright for me in a window seat, when I wish I could have slept!

One of the flight attendants was a little cranky. I appreciated the free wifi and plug to charge my laptop

No entertainment. Plane was so small had to pink tag a carry on ive used for 20 years easily on board. The fact the flight got in at midnight, had to wait for crew in fort wayne to allow the plane to approach the gate, THEN had to wait for bag on jet bridge made experience irritating at best.

Crew was great. Near on time departure and early arrival. Snacks are always meh. Not a fan of the "pay for everything including miles " proposal unless base flight rate going to be 100 bucks.

Would have been better if there was a nonstop flight from Tampa to Norfolk or Tampa to New Port News.

Overall Good! The weather delayed our takeoff from Atlanta and our arrival in Miami! If Mother Nature can mess up a flight she will do it every time!

The flight was smooth, the crew was great but the plane was quite old

Everything was great until I lost my water bottle and they can’t seem to locate it. I know I left it on the plane though.
