i took my pram a bebecar classic chassis and carrycot to teh plane door when going to crete. folded it for teh baggage handlers and it was waiting for me at teh bottom of steps other end.
i would check if you are entering the plane thru a tunnel thing as normally you leave it at gate and they come up for it. at the other end tho you need to make it clear if you need it before picking up your baggage. Tell everyone including cabin staff.
