We were in the back seat even though i had prebooked. We are not short thin people and it was dreadfully cramped and clausterphobic. Plane was out of date. Evrryone brought their luggage onto the plane and ours ended up being halway up the aisle which caused us to be the last folks out. Staff were delightful. Very kind cheery and efficient. I would hesitate before using air transat again. Only if there was no other option to our destination.
