Did you hear? OpenSkies, last of the all biz class carriers, is adding a new route. Starting May 3, they'll begin service between Washington Dulles and Paris Orly. Flights will operate 5 days a week, departing Dulles at 5:45pm and arriving in Orly at 7:40am, and departing Orly at 12:00pm and arriving in Dulles at 2:45pm.
OpenSkies is currently offering a $500 discount on this route. Just enter promo code IADMAY10 at time of purchase, on Flyopenskies.com. This offer is good for travel in May only.
Heck, we've seen economy fares to Paris go for as much, and although this isn't quite a summer fare, May is a pretty ideal time to go.
