I've been a World AA Platinum cardholder for a few years. I got an AT&T Universal Platinum card last year and they would not let me move the credit line from AT&T to my World Card. Today I called to convert my World AA card and did a "Oh, BTW, can I move my AT&T credit line to my new card and she said yes. I told her I would like to move all my credit line but stated I needed to leave at least 1000.00 because it was a platinum card. I went ahead and tomorrow I will call and cancel my AT&T card and now have a nice credit limit on my new citi card. I hated my world would not report a credit limit. Maybe this has been posted and if it has, sorry.
