Thanks to all....it is good information to start with. I think I will try 4 continent starting in BOM (or CMB). Any thought on how I can maximize following itinerary -
BOM-HKG-NRT-SYD-LAX-ORD (2 Month Break)
ORD-LHR-BOM
AS you cane see I definitely need help with latter segments of the trip.
Thanks
