Same as a few others on here. Today I applied for the Citi AA Platinum MC with Link#3 and was instantly approved with $6500 CL. I waited 24 months since my last Citi AA Platinum application and still have that one open. Got the CitiBusiness AA Plat 8 days ago. Will call this week and see about retention offers or if nothing, will close it. Seems like playing it safe you can wait 24 months to re-apply for another Citi AA Plat MC.
