how to get to victoria harbour from hong kong airport

HONGKONG- HK was mainly a part of china and then was colonised by British Empire until 1997.
That is why i can't forget the double deck bus and some of th architectures are still visible right now
There are three types of tickets travelling to and from the airport:
SINGLE JOURNEY
ROUNDT TRIP
SAME DAY RETURN
You can also used the Octopus for the Airport Express
