The Airport Express Travel Pass includes a return ticket Airport/Hong Kong city.

It also includes 3 consecutive days of transport. If I stay 5 days can I use the return ticket to the airport on day 5?

Does the 3 consecutive days for transport begin on the day I go from the aiport to the town, for instance I go from the airport tot the city on the 1 th day, then I can use the ticket the second and third day, or does the 3 consecutive days begin on the second day, so I can use the ticklet ont the third and fourth day?

Thank you very mucht for your answer.
