It depends on the database that JF puts in TG airports that had flights in 1.1.1.6 some no longer have flights, and airports that did not have flights in 1.1.1.6 some now have flights, a problem for P3Dv5 users as the default base airports lack parking some none at all, and the airlines used in the later database has changed as well as the code number in the type box, i get the impression that some new has come in and changed things, and you have a problem trying to see the changes.
