I've been trying to figure out the same thing. I had some miles from the initial signup bonus, and was trying to extend their expiration. I found this Blog Post:
Rapid Travel Chai - You Have 5,000 Copa Miles Expiring Soon, What to Do?
I credited a recent Avis rental to Copa, but it hasn't posted yet.
I tried donating 500 miles, it posted to my account immediately, but it did not reset the expiration.
It is also unclear from the
T&C whether a transfer in from another account would count.
Expiration of Mileage
Mileage accrued in a Member’s account shall be maintained in the account until it is redeemed for an award or until it expires, whichever occurs first. Accrued mileage will expire on the last day of the twenty-fourth (24th) month after the last Qualifying Account Activity in the Member’s account.
Any Member who fails at any time to engage in any Qualifying Account Activity for a period of twenty-four (24) consecutive months shall forfeit all accrued mileage and benefits as of the last day of the twenty-fourth (24th) month. Miles extended through the Extend Miles Program shall be extended for an additional period of twelve (12) months, upon payment of the then-applicable fee for such extension, for a total of thirty-six (36) consecutive months, after which time the Member shall forfeit all accrued mileage and benefits as of the last day of the twenty-fourth (24th) month.
“Qualifying Account Activity” includes, without limitation, (i) earning mileage credit for flights on the Airlines, (ii) earning or redeeming miles with a ConnectMiles Program business partner, (iii) redeeming miles for award travel, (iv) buying mileage, but only as permitted under these Terms and Conditions and in such increments established by the Administrator to constitute Qualifying Account Activity or (v) any qualifying transaction in such Member’s account that the Administrator or the Airlines set forth in these Terms or Conditions. In cases where mileage is for any reason removed from a Member’s account, such as for the redemption of awards, and later returned, the return of the mileage to the Member’s account shall not count as Qualifying Account Activity.
The Administrator and/or the Airlines, in its or their sole discretion, may establish special conditions to, and time limits during which the Member may, reactivate expired mileage, which may be reactivated only during the six-month period following the expiration of the Member’s miles, following payment of the applicable fee for such reactivation.
Would be curious about people's experiences. As this is a young program, the topic doesn't seem to be discussed much.
