I'm looking to book a flight in J from DCA/IAD to AMS next June and the only availability I can find on delta.com is on Delta metal. I've even looked back in April/May and still see only Delta metal available, even out of other cities (JFK, ORD). Why am I not seeing more KLM or Air France availability? Are they just not giving Delta any seats at all? I can't believe in the 3 months I've looked I haven't found a single outbound flight on KLM or AF.

EDIT: Sorry I didn't clarify, this is for an award booking.
