I used Mozio through JetBlue after ticketing my trip to NYC to book a driver service round-trip for Manhattan.
Easy to book and drivers were timely. JFK airport was chaotic so it took my driver some time to get to me due to having to wait in cell lot instead of meet-n-greet, but I received text messages and was able to call and chat. Upon arriving, my car was an upgrade from what I had ordered, both ways. Nice surprise.
