Further details

The node is part of the airport relation, though it's a huge relation including buildings, roads, borders.

There's also a relation for the building=transportation https://www.openstreetmap.org/relation/17538425 The building doesn't have the airport as part of its address either https://nominatim.openstreetmap.org/ui/details.html?osmtype=R&osmid=17538425
