Thanks for the information, and I believe that you are both correct about the opportunity to earn points/kms with other vendors. My main concern is accrual with flights and airline partners. For example, AA flights booked into O don't earn kms under LAN Pass, but do earn points under Fidelidade. Or I notice that points earned via IB flights using Fidelidade expire in 6 months as opposed to the general year for points expiry... the rules for each program seem to have important differences and some notable pitfalls, but considering that I'll be flying more on LATAM, I'm forced to study up. Maybe I'll give up and switch to GOL Smiles.
