Hello,

What source was used to add those ways inside the airport, please?

We recently had some trouble because a user imported copyrighted airport maps into OSM (https://www.openstreetmap.org/changeset/147724524), which goes against established guidelines, not to mention a large number of technical problems (unmatching levels, footways stretching out of the building directly onto the apron, and more).

It looks like your edit is extremely similar.

Looking forward to your reply.
Have a nice day.
