It’s time for Flying Blue’s monthly promo you can travel from NYC to Orly for 46,875 miles one way or 93,750 + $589.08 round trip. This month the Big Apple is the only US city on the list, while Canada has 4 cities from which to enjoy this promo. Since you are not required to buy a round trip using points, my suggestion would be to travel anywhere in Europe on the cheap and then return on business or vice versa. I like this monthly promo because it would be easy to consolidate points from Amex, Chase, Citi and SPG to make the trip a reality.
By the way, you could stay at the Park Hyatt Paris-Vendome for 30,000 points per night and if you don’t have enough points, you could also do Points + Cash: 15,000 plus €280 per night.
