Pros: The flight was reasonably comfortable and got me to where I wanted to go.
The check-in counter employee was polite.
Cons: The male flight attendant seemed engaged in doing his job, but the two female attendants seemed quite unhappy to be there. One of them used her time away from the customers to put on lipstick and make up in the back of the plane (when getting on the plane, she greeted me with a scowl).
The flight was also late in leaving. There was no announcement about this until about 5 minutes after the scheduled departure time.
I would give Lao Air a second chance, but no more than that. Given the choice I would definetly choose Bangkok Airlines instead.
