Have used Flightcar several times with mixed results in LA and San Fran. Last trip to LA used Flightcar but my wallet was stolen at LAX. Had just returned my car in LA and was going to use Flightcar when I reached San Fran. They cancelled my San Fran rental because I no longer has a drivers license. (Flightcar had a copy on file but refused to honor it despite my police report identifying me and the robbery.) I had to use uber and bus system the rest of my trip at great extra cost. Spoke to their customer service rep who promised to look into it and assist me. Never heard back despite my follow up. Stay away from these guys.
