Peer-to-peer car-sharing company FlightCar has expanded its operations to three new airports: Philadelphia International Airport (PHL), Dallas Love Field (DAL) and Washington Dulles International Airport (IAD).

Currently operating at airports in San Francisco, Los Angeles, Boston and Seattle, FlightCar provides its customers with free airport parking as well as the chance to earn money when renting out their unused cars to other approved members.

FlightCar pays car owners when their car is rented, based on the mileage the car is driven, says the company.

“We’re excited to bring FlightCar to Philadelphia, Washington D.C., and Dallas,” said Rujul Zaparde, FlightCar co-founder and CEO. “Our newest location near Seattle-Tacoma International Airport (SEA) is our fastest-growing to date. And today, we’re launching three markets at once to build on the momentum we’re seeing in our other cities.”

FlightCar service includes free drop off and pick up in a town car for both owners and renters, says the company. Customers get the benefit of free airport parking and a car wash, even if FlightCar does not rent out their vehicle.

FlightCar's rates vary depending on the year, make and model, but for renters, the fees are consistently 40-50% lower than other rental car companies, according to the company.

“If you list your vehicle with FlightCar, you are completely covered,” said Kevin Petrovic, FlightCar co-founder and president. “There is no deductible. Your personal insurance coverage is never on the hook. We cover $1,000,000 in liability for you, per incident, and that is primary coverage in case of any incident. ...”

Since its launch, FlightCar has continued to expand and has the financial backing and endorsement of several investors, including GGV Capital, Airbnb Co-Founder Brian Chesky and Ryan Seacrest.
