What the hell is going on with Citi?

I have a totally unused Exec AA card with a 12,500 limit and a non-Exec AA Mastercard with a $14,200 limit.

I want to move as much as possible of the 14,200 onto my Prestige account.

1) when did Citi turn into Nazis about credit line reallocation?

2) what is the most effective US-based reconsideration line? don't feel like searching 40 old threads for the AA card to find the number.
