It states "If no mileage from any source is posted to a WorldPerks member's account for three consecutive years, the account is subject to termination, including forfeiture of all accrued mileage."
To me, this is similar to the rules of the other airlines.</font>
I don't believe that's heavily enforced though. All it says is that it is subject to termination. It doesn't say anything definite like the other airlines do.
