Working on booking a circle routing in Feb/March of next year (ORD-OSL-TLV-ORD) and found decent prices on Air France ($1295), but wonder if I should wait for the elusive (?) fall sales in November? I don't remember having them last year, but I do remember that NWA/KLM came in pretty close to this price last year on a similar routing.

Just looking for advice from the more experienced "bookies"?
