Just an FYI in booking these PE tickets that are upgradeable on LH:
Q fares are not PE, they are just regular economy. PE is an N fare but not upgradeable. You need E class for that.
I am still trying to find out if:
1. The FRA demand will still be higher than for MUC (and thus UG chances in the A380 worse) in the wintertime?
2. I know I need LH flight #s to use GPUs. Do I need separate PNRs to avoid GPU confusion of having an E fare on the TATL and a regular Y fare on the short EU connection?
