You paid Euro 193 and are satisified ! Charging huge fuel surcharges on award tickets is a rip off. First, this charge was not disclosed when we earned the miles. Second it doesn't cost the airline more than 15 Euro in additional fuel to add one passenger, which is only slightly more than the 5-10 Euro it used to cost a few years ago (and hence is included in the miles for the award), so charging more than a 10 Euro surcharge on awards is not justified based on the increase in fuel cost. Do they have class action lawsuits in France ?

BTW if you had flown KLM, the award would not have included any fuel surcharge. Avoid AF metal (unless you get First Class).
