Here’s a new twist in the Peer Economy I don’t think will work, especially as ridesharing becomes more popular: You don’t have to pay for parking at the airport (and you’ll receive other amenities) if you allow your car to be rented while you’re out of town. From Lori Aratani at the Washington Post:

“A San Francisco-based company is putting yet another spin on the Washington area’s sharing economy, giving travelers flying out of Dulles International Airport free parking and a car wash in exchange for permission to rent their cars to other drivers.

FlightCar launches Wednesday at Dulles and two other U.S. airports. Participating travelers can drop off their cars at a designated lot near Dulles. In exchange for letting FlightCar offer a vehicle for rent, the travelers receive free parking, a Town Car ride to the airport, a car wash and per-mile payment if the vehicle is rented — to a pre-screened driver — while they’re away.

‘Everyone goes to the airport, everyone has trouble parking, so it just make sense,’ said Kevin Petrovic, president and co-founder of FlightCar.”
