Not sure whether I should post this in the AM or BA forum, but thought I'd start here.

I have enough AM to redeem for 2 JNB-CPT tickets on BA, and enough BA miles to redeem 1 ticket on the same flight.

BA.com showed more than 3 seats available for my chosen flight.

I called AM to redeem the 2 seats, AM customer service contacted BA to hold the 2 seats prior to ticketing. My AM redemption was then processed.

After which I immediately tried to redeem for the 3rd seat on BA.com but the entire flight has disappeared!

Questions: When AM calls BA to hold the 2 seats in question, does BA place a "stop redemption" on the entire flight and not just the 2 seats? My AM redemption hasn't been ticketed yet, but once the 2 seats are ticketed, I sure hope the rest of the availability will be released on BA.com - will they?
Has anyone experienced similar issue when redeeming through different FFPs for OW seats on the same flight?
