so Munich and Frankfurt are the main base for B75/767 ops.?
All longhaul flights depart from Frankfurt, there is a significant operation of 757s from DUS, STR, MUC and to a lesser extend from HAM. This changes somewhat from one schedule period to the next.
A320 fly from the same German airports, in addition to HAJ, SXF and LEJ. This of course is not fixed. Currently, if I recall correctly, people will be based in HAJ, SXF or STR when joining the A320 fleet.
