How to get from the cruise terminal in Hong Kong to HK airport using the MTR?

You must refer to Kai Tak Cruise Terminal. Well, there is no MTR station within walking distance to the cruise terminal. Well then, here are two ways for you to choose:
1. take a taxi from the cruise terminal to Kowloon station in 20min and then take Airport Express train to HKIA.
2. take green bus no. 86 from the cruise teminal to Kowloon Bay station. Then walk to Telford Gardens, Kwun Tong Road to take bus no. A22 to HKIA.

Thank you so very much!
