I suspect what AF did is cancelled your seat assignments so someone else could sit together. ANd since you both were on separate PNRs, they probably didn't know to keep you together.</font>
Agree completely as it has happened many times on UA w/my wife flying an award ticket so therefore different PNR's. It is AF's fault, but sometimes there is not much you can do about it.
You can bet that AF would receive a letter from me in regards to the matter though.
