Air France-KLM has updated their promo award page mid month and added an interesting award from Europe to Panama city for travel between November 25 and March 31, 2014, that is booked by August 29.
You only need 15,000 miles for one-way promo award in economy that is a good deal now that the fuel surcharges on these economy awards are capped. The premium economy is 30,000 one-way and business 37,500.

This is a good deal for cheap one-way from Europe to Central America or the other way.
