I am planning to travel from PNQ-AUH-JFK-AUH-DEL in Business class with the following itinerary:

PNQ-AUH (9W-Jet); AUH-JFK (EY); JFK-AUH (EY); AUH-DEL (9W).

I have a EtihadGuest Silver and JetPrivilege Platinum. In which of these frequent flyer program should I accumulate the miles to maximize the benefits?

I feel that though it might seem that I might accumulate more miles in 9W JetPrivilege due to Platinum status but that might be deceiving and not true.

Any expert comments / experience?
