If you really can't book a usable ticket before it expires - meaning you can't find a way to book an AFKL flight in the next year* - then please try this, and come back and tell us what happens when you cancel the ticket.

(Given that you are an FB Gold based in Paris, it seems very unlikely that you cannot see your way to buying a flight now that you can use at any time in the coming 10-12 months).
