Just log into MMB and enter your FF number to see the miles, or if it's a non-EK number and it isn't displayed (I don't know if it would be) you can use the Skywards calculator on the site: https://www.emirates.com/account/in/...alculator.aspx

FWIW the difference between SIN-JFK and SIN-DXB-JFK on a great circle route is less than 10% (9108nm via DXB vs 8288nm direct). Full fare Y on EK earns 9,500 miles.
