Thanks for all the information guys, unfortunately I won't have a lot of time to do mileage runs within europe/asia (yes, I know it'sacrilage to say so on this forum ) What I'm hearing then is, as a US citizen, it's best for me to go LAX-LHR-EDI-LHR-HGK-LAX, making sure that I'm booked in "D" space on the segments I'm travelling in order to get 1.5 QP's. Does anyone know if I can stay "in transit" in HGK or do I have to pass through customs when arriving there? (need to know if I should get a visa or not). Thanks once again everyone
