well, i do not have an BAEC account yet...
my itineray is in D and Y (no discounted classes) so this trip would earn 9277 miles on QF. almost 10.000 which I could fill up...
but, I guess these one-way awards do not allow any stopovers so I could basicly only fly txl-hel-muc so beside some extra flying, there would be no benefit, right?
