Over head compartment seemed a little small but wasn’t overloaded. The Airbus plane had 2 seats on one side and 3 on the other. My wife especially liked the fact we only had 2 seats on our side of the plane. I like being at the window she likes being on the aisle not middle seat. She appreciated have her own video screen with lots of movies available on the back of the seat in front of us. She also appreciated that the flight was on time. The crew was great.
