Hi,

I booked business redemption tiket below:
mar 6th, sub-hkg-can
mar 11th, can-hkg-sub

and I decided not to use the mar 11th can-hkg ticket because I plan to go to Macau from Guangzhou by riding bus.

Now my question is, can I do that? Do I need to inform cathay pacific if I don't use one of those ticket?
