Ok, this is the itin I have in mind:
BCN-ZRH-FRA LX J
FRA-SIN LX F
SIN-AMD SQ J/F
Is this poss on a Z2-Z10 redemption on Cash+miles?
I was looking at RT ticket for avoidingthe HIGH Indian taxes but I think going by the advise here I will book a sinle trip to AMD and on the way back I will work out some other routing........another task for later
