You can bring your stroller or buggy, but they need to be labeled as baggage item.
In Terminal 2 you can take your own (labeled) buggy or pram with you up to the aircraft door.
In Terminal 1, you can hand over your stroller or buggy at the check-in desk like a regular baggage item. Immediately after the Terminal 1 security checkpoint, you can borrow a buggy free of charge.
You can hand in child car seats as bulky luggage. With some airlines, you can also use car seats as a restraint system in the aircraft. Please contact your airline in advance for more information.
If you don't bring your car seats or buggy on the vacation, you can hand them in at the Left luggage point in the Service Center at a low charge.
