Hong Kong Airport Express Travel Pass (HK$220) - Single ticket

Hey guys,

I have one doubt about the Airport Express Travel Pass - 1 Airport Express Ride.
Is it possible to use the 3 consecutive days of unlimited rides on MTR first (ex. mon., tue. and wedn.) and after 2 days use the airport ride to go to airport (ex. friday)?

I couldnt find the MTR email to contact then. I'll arrive in HK after midnight so wont be able to use the airport express metro, thats why I`m planning to use the airport express ride on my last day.
