Hong Kong's Airport Express, run by MTR, is probably the best transportation facility for tourists to reach their hotels from the airport. It only takes the train 20 minutes, approximately, to reach the Kowloon Station. From there tourists may take the courtesy shuttle buses, which are also run by MTR Airport Express, to reach their hotels. At the Kowloon Station, there are airline counters for issuing boarding passes and checking in luggage for their passengers.

The fare is only HKD90.00 each way.
