Upgrading Airmiles tickets to Non-Expiring

[My 2 princesses]

Is this possible? Can you redeem miles for the 5 day pass and then convert them to non-expiring?

Yep you can upgrade the base tickets with any options on site... although I would consider the number of days you'll have left over before upgrading for the no expiration option... if you're only going to have a day or two left over it may be better just to get new tickets the next time you go.
