Pros: Quick boarding. Inexpensive ticket. Direct flight.
Cons: Crew walked thru cabin at least 5 times collecting garbage, but could not hand out sealed snack or sealed water. People sat should-to-shoulder - No buffer space, but asked to leave the plane with 6 foot intervals???? This airline picks and chooses their Covid precautions. Quick and inexpensive flight, if you don’t mind the rest.

Pros: The flight wasn't full which is always nice and they served full size cans which is also a nice little note.
Cons: The plane was pretty old and people just started sitting wherever. It was chaos as my wife and I sat in our assigned seating and just watched people wander like animals.
