But one does not get the $125 credit for UA spend until after the one-year account anniversary.
"
Receive up to $125 in statement credits each account anniversary year as reimbursement for United purchases charged to your United Quest Card."
Likewise the three miles per dollar of UA spend does not start until then.
"3 miles per $1 spent on United purchases immediately after
earning your $125 annual United purchase credit."
