India usually is seperate from Asia in most airlines award charts. Asia usually refers to the countries in East Asia.
Taken from UA's website the award travel mileage requirements for travel to India from US and Canada are:
Saver Awards:
80,000 Economy
110,000 Business
130,000 First
Shareholder: You mentioned 160K for a first class trip to India. I was wondering if that was a Standard Award mileage rather than the Saver Award mileage.
