I monitored flights as soon as I was able to book and called the partner desk. Got a very nice lady in Boise. I am traveling PUW-SEA-LAX-HKG-JNB and back again in First SEA-LAX-HKG and then business HKG-JNB because planes don't have a first class on this route.
I'm super excited, but I kept watching inventory on britishairways.com and searched for award inventory in the spending avios section. I had to do each segment at a time. Kind of a pain, but well worth it!
