But why will HAM and TXL work if DUS and MUC didn't??
Running smaller aircraft, the 752, most likely. When CO
before it was with the DC-10-30, I believe, and that was probably too much capacity for the route. With the 752, you have a plane much more suited for the route.
Oh, by the way, don't be surprised if MUC
are started back up, using a 752 or a 762....
