Jet Airways flies the 777 daily between Toronto and Amsterdam and they are a Virgin partner.
With the current 30% Amex bonus, the effective cost would be:
Economy (3-4-3) - 15,770 Amex
Business (1-2-1, herringbone) - 31,539 Amex
First (1-2-1, suite) - 46,154 Amex
Amounts are for OW, RT would be double.
No YQ is added for Jet Airways awards, so total tax would be a little over $40 from Toronto to Amsterdam.
