FlightCar, Peer-To-Peer Car Rental Program, Debuts At San Francisco Airport

Parking at the airport can easily run $20 per day. That’s in the “cheap” long-term lot, requiring a long shuttle ride to the terminal. Valet service can cost way more. But what if you could get airport parking valet service totally for free—with a car wash and free gas to boot?

That’s the gist of the offer from a startup called FlightCar, which began offering its service at San Francisco International Airport in early February. What’s the catch? In exchange for free parking, a free car wash, and a gas card worth up to $10 for each day the car is left behind, owners agree to allow FlightCar to rent out their vehicles to customers — i.e., strangers. The business model basically brings peer-to-peer car rental services such as Getaround and RelayRides to the airport.
