Cons: The size of the seats

Pros: The flight was smooth and we arrived safely.

Cons: When we went to check in (right at 24 hours), our family of three was separated across the plane in middle seats—and they wouldn’t seat us together unless we paid extra to upgrade our ticket. The ticket agent said the plane was full and there was nothing they could do. It was very frustrating.
