Actually, I did book my flight on NW.com, it was part NW part KL through AMS. Then I saw on Delta.com a part DL part AF flight, that was 1/2 the price ($700 vs $1500). I was within the 24h window so I canceled the NW flight and booked DL, which is all DL metal on the way over (TXL via JFK) and AF/DL on the way back (SJC via CDG, LAX). I'm starting to regret booking on AF/DL given the shoddy customer service (1/2hr to get a representative, who then "called AF" and told me he couldn't do anything), and the fact that AF refuses to assign exit rows.

*sigh*. It was a big cost savings, at least....
