), the world's first peer-to-peer car-sharing company to operate at airports, has expanded operations to include Philadelphia International Airport (PHL), Dallas Love Field (DAL), and Washington Dulles International Airport (IAD).

FlightCar, which already operates in four other major U.S. cities (San Francisco, Los Angeles, Boston, and Seattle), enables its customers to enjoy free airport parking and earn extra cash by renting out their unused cars to other approved members. The service includes free drop-off and pickup in a Town Car for both owners and renters. FlightCar's rates vary depending on the year, make, and model, but for renters, the fees are consistently 40 percent to 50 percent lower than those of typical rental car companies. Additionally, FlightCar insures each vehicle for up to $1 million on property and liability, offering protection for owners and renters alike.
