While previously the terms on the U.S. Bank Altitude Reserve card (direct link) excluded previous cardholders from getting a bonus, the terms have now been updated to allow churning after 5 years.
One-time 50,000 bonus Points will be awarded if you are approved for a new U.S. Bank Altitude Reserve Visa Infinite Card and eligible Net Purchases totaling $4,500 or more are made to your Account within 90 days after Account opening. Points are earned on eligible Net Purchases. Please allow 1-2 billing cycles for your bonus Points to be credited to your Account. Existing or previous U.S. Bank Altitude Reserve Visa Infinite cardmembers are not eligible if you have received a new account bonus for this product in the last five years. Use of the Card is subject to terms and conditions of the U.S. Bank Altitude Reserve Visa Infinite Cardmember Agreement, which is provided at Account opening and may be amended from time to time. This offer may not be combined with any other bonus offer.
The U.S. Bank Altitude Reserve card launched in 2017. The card comes with a 50,000 points bonus, worth $750 on travel. Previously all prior cardholders were excluded from getting a signup bonus, and now only those who received a bonus within the last 5 year are excluded. We’ll update our post List of Churnable Credit Cards with this info.
