Applied with 30K bonus, need promo code for widely advertised 50K bonus
Hello folks! First time writing here. I recently received the Citi AA Platinum card after applying through a promotion offering 30,000 miles with $1,500 spent, but I have now noticed they are offering 50,000 miles with $3,000 spent. I called to see if they would honor this new promotion since I'm a new customer, and they said they would if I had some sort of offer code to give them.
Can anyone point me in the direction of where I can find this? I would truly appreciate it! Also, any other tips for using my card to the fullest? Appreciate anything and everything
