Last year, I applied for a Chase Visa and was awarded 30,000 Mileage Plus miles. The card is now up for renewal, for a small amount ($60), but I'd prefer to cancel the card, and apply for a new card (that will award me 25,000 Aadvantage miles).

1) Does anyone know if my failure to renew will permit them to reclaim the miles?

2) More importantly, can anyone direct me to the Terms and Conditions that discuss vesting, forfeiture, etc. of miles.

Thanks
