Most of the aircraft you refer to are not owned by Germania but by SAT
-Flug, a leasing company owned by the same person who owns Germania (he also owns a couple of 737 outright).
The "GOL"-ones are now longer owned by Germania/SAT
. They were sold to a leasing company (cannot remember which one) that leased them to GOL. My understanding is that Germania now has only ten -700s in its books, 8 leased to HLX and 2 to Azzurra Air.
One -300 (UR-GAH) was recently returned by Ukrainian and should be in Germania service shortly, together with D-AGEJ/K.
To the best of my knowledge, the Fokker 100s are, contrary to many reports, only leased and were not bought by Germania.
