You can drop off your baby carriage or stroller right at the departure gate. After arriving at your destination, normally it is returned to you when deplaning or else you can pick it up at the baggage claim (possibly at the pickup point for bulky items).
The buggies are available in Terminal 1 at the service point in public area B and in transit area B at information desk 10.
In Terminal 2 there are the buggies at the service point between area D and E, in the public area. The prams can also be returned there.
But if you take off or change planes, you can simply leave the buggies at the gate. Airport employees are collecting them back there.
Only the flight information is needed. Buggy rental is free and for children
from 6 months and maximum 15kg.
