The FC seats available for upgrade are listed as "F". "A" are full fare FC seats. Yield management eventually starts moving A seats to F as flight time gets closer.
Also, when there are nine or more seats available in a given bucket, ITN will only show "9". Apparently, this is the same as what the rez agents see.
You should be able to upgrade immediately on the 9:40AM. I'm pretty sure of this, however I am former Platinum who's been demoted to silver.
