Sorry if this is already out there but I have cone a search and have not come up with anything real helpful.

When I go to www.seatcounter.com and search only UA I easily find upgrade availability but if I search other *A flights, the UA codes disappear and I am lost as to what are award seats ie both upgrade and "free"

For example I am trying to find upgrade availability for seats on LH DEL-MUC and LH MUC-DEN from C to F

Any help would be appreciated

Thanks
