Hello, Can I use the ferry to HKIA when I need a flight, no matter which airline?

If you depart at Fuyong port at Bao'an airport, it's no problem and you can take the ferry to HKIA SkyPier.

But if you depart at Shekou Port, there is the limit on the airlines. Only the airline who open the service at Shekou port can be allowed to make their passengers take the ferry in this port.
