I know that DL used to fly CVG-MUC and JFK-MUC a few years ago. I also know that CO flew in 1993 1994 EWR-MUC using a Dc-10. Also it seems to me that AA flew a route out of MUC in the early nineties, but I am unsure.
If you have the schedules of these flights, please could you post them here ? Especially the DL and CO ones.
Also, do you see any of these routes/carriers coming back ? To me the most likely is AA. They could fly MIA-MUC and even JFK-MUC. This route could also work for DL. After all DL used to have a major presence in MUC with three or four daily flights, so who knows ...
Thank you in advance for your help.
