Circumstance: UA: Lifetime miles are earned only on UA metal. Mileage accrued on CO or other Star Alliance carriers does not qualify for lifetime miles and consequently million miler status. CO: Lifetime miles earned on UA and all Star Alliance carriers counts toward Lifetime miles. How this impacts you: 1) 2011 tickets purchased from UA with travel on CO credited to MP... earned mileage does not count toward million miler status. 2) 2011 tickets purchased from CO with travel on UA credited to OP... earns million miler status Consequence: This does not make me happy. Lesson Learned: Remember to credit all CO and non-UA Star Alliance travel to your OP account. Moral: 1) Don't let THE MAN keep you down. 2) Stick it to THE MAN as and when the opportunity arises.
