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.
