Please, please, please read the innumerable posts about AmEx made over the last several months. Things have changed! It's not smart to immediately request a product change and try to wangle CLI's.
Just use the card you have, enjoy the rewards that come with it, PIF every month, no matter what, keep all your other CC balances low and paid timely, and let your Delta cook for a year before initiating anything. If they grant you a CLI sooner, great. But no one these days should poke a stick at the sleeping AmEx dragon. Too many other singed people out there from trying this!
That's what these forums are for --read about others' experiences and profit from them. Congrats on your new card, and good luck.
