I was also originally in C on the return segment, then I changed to confirm myself in F, and then I changed the outbound date... In the end all 4 of my CX segments are now in F...
Since you are based in SEA, all three airports are an option for you and I am pretty confident that F space will open up from one of the three airports within a few days of your currently booked day of departure between now and Aug/Sept.
So, book it, since you are a Gold, worst case scenario you will bag the trip and lose $25 [non refundable partner award booking fee]... Monitor the BA Executive Club site for any F space that might open up, don't use the CX site, because it gives you more award space than what AS sees.
