Can't add any more, other than to advise that is almost ALWAYS better to hold off on buying a ticket until you know you will actually be able to travel.

Given that you now know you're not traveling, if the decision had been the other way, you could now purchase a one-way for travel in March that is about half the price you paid to AF.

Don't pay more than you have to - wait to buy until you know you're going to have to fly - and then, buy the cheapest possible ticket you can find (and not the "more" expensive "refundable" ticket that you bought earlier)
