If I understand correctly, they are just not letting the planes belonging to the charities to fly out of those fields. So it’s not the landing that’s prohibited, it’s they can’t base themselves there.

Also, you technically are required to take an extra hour of fuel because airports close all the time. In theory, the airport has the right to tell you to land it in the field sonewhere.

Not that I support the Italian government in this shady shit.
