This is too bad. I used the service probably five or six times. They were always my go to for renting a car from the airport. (Never used them to lend out my own car, however.)
Interesting to note, PG said this about FlightCar in 2013: "They went from what seemed like one of the least promising startups in the batch to one of the most promising in the batch." (http://www.bizjournals.com/sanjose/news/2013/03/27/smaller-c...)
FlightCar anecdote from the early days: I rented a car from BOS and drove it to a wedding about 4 hours away. Got a call from FlightCar that they actually needed the car back (don't know if the owner returned early, or it was a scheduling screw-up.) So someone drove the 4 hours to me in a different car, met me in my hotel parking lot 30 minutes before the wedding, and we swapped cars. :)
