I am booked in Oct SCL - ATL. I wanted to change that segment but didn't want to pay the $300 change fee. Long story, but since there is an AF segment in my itinerary (006 ticket stock though) apparently AF can demand a change fee, even though their flight is not affected. Anyway, now I am hoping for a cancelation and the ability to rebook for free. My flight on Oct 11 shows as status not available, so there is hope.
