Expiry of Miles

[SQ354]

A quick question as I couldnt see the answer on the wonderful SQ website.

I have expiry of 250,000 miles August 2013. I know I can extend for 6 months or 12 months if I want - although working out the fee is confusing. But if I didn't extend, do I have to have actually flown with Mrs SQ354 and used them all by the expiry date - or as a minimum booked a flight sometime after, say Feb 2014?
Thanks

Booked is good enough. However, if you cancel the booking, wave the miles bye bye.

Thanks for the reply. What if you book, the expiry date has come and gone, but you want to change the date of the booking. Is that allowed or classified as 'cancelled'

You may book the ticket before Aug 2013. All award tickets are valid for 1 year. After booking is confirmed, you may change the date of ticket to a further date.
You may try to rebook the ticket with a new destination and some miles/$ will be charged.
However, if you want to cancel the ticket, the webpage will show you how many miles are going to expire at that moment, if you click cancel, I think those miles will gone immediately.
