Keep in mind that my spend doesn't hold a candle to yours, so I always focus on sign up bonuses.

I'm not gonna sit for hours and analyze your patterns, but off the back of my head between the 2 of you, you need to hit the following:

Both of you apply for Amex SPG Biz

1 CSP and Ink whichever you don't have.

Hitlon cards: 1 from Amex, 2 from Citi, 2 Hawaiian, and Virgin Atlantic, perhaps Amex Surplus too.

Both of you apply for Chase Hyatt and Fairmont. Get the match for Hyatt Diamond before applying.

Both of you apply for US Bank Club Carlson, personal and biz.

Another Barclays Arrival

Both of you for Chase Marriott and Priority if you still want something else.

With your spend capabilities, it's freaking scary what you can achieve.
