KLM will park two Airbus and ten Boeing 737 aircraft at Groningen Airport Eelde in the coming winter season.
Due to the corona crisis, the airline carries far fewer passengers and aircraft are unused on the ground.
The capacity at Schiphol is limited, KLM announced on Wednesday.
That is a reason for the company to move to Eelde.
The aircraft are inspected from time to time and are also well protected against possible bad weather at the smaller airport, the company says.
KLM currently operates less than half of the usual number of flights.
Since the start of the summer timetable, many aircraft have been grounded and the winter timetable has also been stripped down.
