Cathay Pacific Asia Miles - cx redemption

I m going to redeem a cx flight from sfo-hkg and return but on the return flight I might stay longer. my question is if I change the return date, will cathay charge a change fee ? if yes then whats the fee going to be ?

Thanks

If redeemed with CX's own Asia Miles, no fee.

How come when buying a ticket and want to change the return date they charge a $100 fee and not on a redemption ?

Different fare rules.

Also - one key issue - award travel is subject to inventory control.

my recent story here.

I redeemed HKG>YVR and LAX>HKG J class on 7th Aug
Suppose I was planning come back on 17th Aug, but CX only able to give me 16th. I redeem it anyway and told CS wait list for me (3+1 infant J tix)
On tuesday (14th Aug) I got an email from waitlist@cathaypacific.com title : Change of your booking status‏
saying
"Dear XXXX,
Your booking on Business Class of CX885 (LAXHKG), 17Aug12 has been confirmed. Please check details on Manage My Booking."
At the same time my wife got a SMS too, but not me (strange eh?)

So I quickly call MP/AM the 1-886 number (mind you the 800 doesn't work on stupid AT&T and T-mobile) and confirmed all 3 seats + 1 infant.

Easy as 1 2 3 :)

and yea, no single dime charged :)
new J class is awesome, my 1.5 years old was happy sleeping & wandering around the J area whole flight.

Well...revenue TKTs are, too, except easier to get a seat.
