If you’re spending $200k/month, you could do $250k in your name and $250k your spouse’s name (if appropriate given your business, I assume you are the owner) and you would both be diamond. As a DM in NYC, I’d say I clear into FC about 50% of the time (used to be higher even as a PM in 2019) and that’s often with one companion. This would get you RUCs and GUCs to use on your travels as well as sky club and centurion lounge access.
IMO, your best bet is using your points from Amex or Delta reserve or other travel ccs to buy first for special vacations especially if there’s only a few per year.
