Basically, the handling of the luggage as well as strollers is the responsibility of the respective airline due to the contract of carriage concluded with the passenger. Air transport also includes the period during which the baggage remains at an airport.
The measure that guests in Terminal 1 must deliver their own buggy or stroller at check-in in Terminal 1 was introduced in 2015. At the request of the airlines, passengers are asked to place their own strollers at the bulky baggage counter and, after the check, to use a rental buggy provided free of charge by the airport until departure. The background: On the one hand this measure serves the acceleration of the security control processes, since the examination of the cars is omitted. On the other hand, this eliminates the costly loading of the stroller at the position.
In Terminal 2, it is the passenger's decision to give up the stroller at check-in or hand it over to the loading staff when boarding. In the latter case, the stroller can be marked by the airline as a "delivery at aircraft" (DAA). The output then takes place at the aircraft door. As a rule, a DAA-marked stroller can be picked up by the passengers directly on the plane.
However, different requirements of the different airlines have to be considered. In some cases, due to the instruction of the respective airline, a delivery of the stroller but no distribution is practiced at the aircraft entrance. In some cases, due to infrastructure constraints (no lift, narrow and steep staircases) it is also not possible to operate in accordance with the DAA procedure. In these cases, the passenger unfortunately only gets his stroller in the arrival hall.
We regret that due to the competence of each airline, Munich Airport does not have a uniform standard for the treatment of strollers.
