US Credit Card Guide is reporting that the Citi Prestige 75,000 point signup bonus offer is still alive in-branch through tomorrow. You would have to go in-branch to apply and they are showing a screen shot of a marketing material showing an end date of 10/7/17, so this is truly a last call. The online offer has already changed back to no signup bonus, so if you’re looking to take advantage of a signup bonus on the Prestige card, this looks like your last shot for a while.
As a reminder, this offer requires spending $7,500 in the first 3 months and the card has a $450 annual fee ($350 for Citigold / Citi Priority or Private Client members) and includes a $250 annual airfare credit and the 4th night free benefit. I recently wrote about my experience using the trip delay protection with this card (See: My $500 trip delay claim with Citi Prestige) and I was impressed with the ease of using it, even at the max end.
YMMV as to whether or not this is available in all branches.
