Expertflyer doesn't show awards on LH anymore (from what I've seen/read). I'd like to go business or first (only 15 days out?) on DEN-FRA and then FRA-BIO. United site doesn't show any (coach, business) directs to FRA from DEN-FRA or DEN-BIO, but does show FRA-BIO business availability when I look DEN-BIO. Should I assume that no LH award seats are available DEN-FRA? Any other suggestions? We're looking to get to San Sebastian so I can also use UA to get to LIS or CDG (or ?) and then train it. Semi stupid question, but can/should I link my UA miles to LH miles & more? I've never signed up for miles & more account and have always used my UA miles for award tickets on *A. As always, many thanks in advance.
