My wife got 100k upgrade offer too. 2nd year of the card. ~10k/yr. Upgraded. Just very curious what/when will we get for the anniversary night. Original anniversary will be early Nov. Many banks will reset the anniversary. But based on T&C, maybe not for this upgrade.
Annual Membership Fee: Approximately 45 days after your account is upgraded, you will be charged a prorated Annual Membership Fee for your new Card based on the time remaining until your next account anniversary date. You will also receive a prorated refund for any annual fee paid on your previous Card.
