Pros: The comfort of the plane was great! Lots of room and very comfortable seating.

Cons: I found some members of staff to be a bit rude. When other passengers asked questions or did something wrong (that was a minor issue), one of the staff members in particular talked down to them and treated them like they were stupid.
