Curious, how did you get that routing? Last I checked, SEA-SFO-JFK was not a valid routing for D1 fares, forcing me to take the one daily D1 (75S, not a 767) SEA-JFK flight.
LAX-SFO and SFO-JFK were booked as one ways. First flight was booked using miles and the second flight was a cash booking in economy with an ruc being used to move up to D1.
