Inactivity rules are common
Under an inactivity model, miles remain valid if the account records a qualifying earn or redemption within the stated period. The clock may restart after each eligible transaction.
Some programs use fixed expiry dates
A fixed-date system can cause points to expire a set number of months or years after they were earned, even if the member remains active elsewhere in the account.
Not every transaction resets the clock
Logging in or moving points between internal categories may not count as qualifying activity. Members should check what the program specifically recognizes.
Small activity can sometimes preserve a large balance
A modest partner transaction, credit-card earn, mileage purchase or small redemption may extend validity in programs that use activity-based expiration.
Reinstatement may be possible but costly
Some airlines let members restore expired miles for a fee or after completing a challenge. The cost can exceed the value of the balance, especially for small accounts.
The safest approach is to track the rule, not assume it
Program policies change. Members with meaningful balances should note the stated expiration method and verify it periodically rather than relying on old advice.
