Hello guys,

I am Sahil and I am from New Delhi, India. I am going to be going to the USA for college this fall. I am most probably going to Sarah-Lawrence College which is located in southern Westchester County, New York, in the city of Yonkers, 15 miles (24 km) north of Manhattan.

This will be my yearly plan for the next 4 years:

1. Go in August and come back in December
2. Go in january and come back in May
3. Repeat for the next three years

I am a part of the British Airways and Lufthansa mileage program.

So my question is: What is the cheapest and best way to travel from New Delhi, India to New York, USA. With which program will I get the cheapest ticket and the most points? I plan to start going in Economy and upgrade when I have points...

Anything else I should tell you?

Thanks
Crazysah
