i recently enquired about a *award from FRA - CPT. the CSR found FRA - LHR - CPT (on LH and SA). i then asked if i could book it from PRN (prishtina, kosova) hes said the routing (VIE-FRA-LHR-CPT) would be backtraking and not allowed. i'm curious what this backtraking is and where i can find more information. IMHO FRA - LHR should be backtraking as well.
