Considering that a couple of years ago fares to Paris were sky high in cramped economy seats, and that even now if you choose the wrong travel dates you could pay over $1000 round-trip for said seats, it's pretty cool that Air France is having a sale on what looks like some pretty plush new seats in their new premium economy cabin on this route.
Fares start at $591 each way plus about $120 in taxes.
The fare is valid for departures October 25 through December 19, 2009 and for departures December 25, 2009 through March 31, 2009. There is a 21 day advance purchase for this fare. A minimum Sunday night stay is required and a maximum 1 month stay is permitted.
