So I fixed my problem. Instead of flying into TXL and having to deal with an immediate transfer, missing conformance and trying to get on a later flight that was empty but didnt have point seats available. I made TXL my return flight and am now flying in to MUC at 850 so 2 1/2 hours for a transfer plus a chance to visit the Concord room. Plus I now have a full extra day in Europe before flying to London for a day then up to MAN.
