Congratulations on your approval through Navy Federal!
You got a great start. My first card with them was the cashRewards, and they gave me a $500 limit. "Wait until the second card, they'll really give you a huge limit!" I heard. So I got the More Rewards AmEx, and they slapped me with $500 again.
A few weeks ago I tried for, and was approved for, the Flagship at $9000. Through CLIs I've gotten the cashRewards up to $3000 and the More Rewards up to $1500. Just be patient with Navy, they are definitely relationship based, and they take a quick liking to certain people/profiles over others. If you look across this forum you'll see people that get 20k right out of the gate with what appears to be (on the surface at least) a very weak credit file, and then there's me, who they hit with $500 twice.
