Mystery of the disappearing redemption availability
 

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?

Have you thought about the possibility that someone booked the same flight while you were making your booking?

Very very unlikely... there are about a dozen flights a day on BA on this JNB-CPT route and when I checked minutes before calling AM, there were 4+ seats in J and 4+ seats in Y for redemption. I still suspect entire flight's redemption is put on hold as long as there is a seat that's been reserved for a OW redemption (not sure whether the fact that this is a Comair flight operated as BA has anything to do with it).

Will check as soon as my AM redemption is ticketed to see if the flight hold is released.
