FlightNuts

Flightnuts is a site where travellers can buy, sell, trade, swap, barter, gift or donate frequent flyer miles, rewards points, flight vouchers, free tickets, and other types of travel credits. Users can search for plane tickets by airline or destination, and subscribe to get alerts when someone posts what they need. Flightnuts is a great way to book international flights and domestic flights much cheaper than going rates, or to turn extra frequent flyer miles into cash or other goods. Flightnuts includes available miles from American Airlines Aadvantage, Continental OnePass, Southwest Rapid Rewards, Delta SkyMiles, United Mileage Plus, British Airways BA Miles, Virgin America Elevate, Virgin Atlantic Flying Club, JetBlue TrueBlue and US Airways Dividend Miles.
