So I was going to book the deal to IST (IAD-IST) through the DL site. I see some of the flights are actually with KLM and the flight numbers don't match what would be eligble under partner earning for DL since it only lists DL numbers. But if I book the exact same flights through KLM (and pay more $$) then those flights come up as eligble. Does that mean I can't book them through DL? Wasn't sure how exact the code table is for flight numbers on the website. Any help would be great
