I currently have the Delta Skymiles Amex card. Would American Express let me have the Hilton card as well? Wise or dumb move?</font>
You could probably increase your total Amex LOC faster by getting a new card than by trying to get an increase on the DL Amex. For Amex, I have the DL and Starwood cards. Normally I keep most of my LOC on the Starwood and just keep enough credit for the always-double-miles stuff. But when there's a promo on the DL card, I shift most of the LOC to it. I think I've shifted my LOC 7 times this year.
