Share limousine to hong kong international airport

You may contact the limousine operator if they can help you find car-sharing passengers.

Or why don't you take the ferry from Shekou Port? If you are near the Futian Bus Station, you can take subway Luobao Line from Zhuzilin to Window of the World, and then transfer to Shekou Line to reach the prot directly. There the ferry would be faster than limousine.
