Maybe your curious and want to get started. Here is how I’d advise benefiting utilizing current offers.
I recommended switching from putting the majority of your spend on AmEx Membership Rewards and move to the more flexible Chase Ultimate Rewards program. Here is a blog that breaks down the best uses of the Ultimate Rewards program:

VERY IMPORTANT – in order to maximize your points, never (NEVER!) apply for joint credit. Want you want to do is each of you apply for each of the two cards individually because you can only get the bonus points once lifetime. If you apply for joint credit then you only get one bonus. If you apply individually then both of you get the bonus, and then we can combine accounts.
