TimesPoints, a rewards program for United Airlines employees and their families, can expire if not redeemed. There are three possible statuses: Lifetime, Expired, or Redeemed. If an account reaches its redemption limit, it will be marked as expired after one year from the date of credit. To avoid expiration, individuals must redeem all available TimesPoints before they lapse.
