I'm about to hit my first Amex platinum renewal---I basically got it last year when I was staring down the gun of a many-hour layover in LHR with no status and decided, WTH, let's try the centurion lounges. Trying to decide if I should keep it---would love any advice!

My situation: I live in Chicago, and do a lot of short (domestic) work travel and a little personal travel (a couple trips to CA a year, between 0-2 international trips a year). I currently have the Amex platinum with something like 140k MR points and the CSR with a similar number of UR points.

At the beginning of this year, I took stock of my impending travel and decided that it makes sense to go all in on United. They dominate ORD, and there isn't even a centurion lounge in Chicago (and I value lounges). So I grabbed a third high-fee credit card, LOL, namely the United club card, and promptly earned the SUB on that, so now I have 100k United miles as well.

My reasoning for maybe letting the Amex platinum go is that this year if I make sure I don't set foot on any other airline, and taking into account that united counts award travel using their own mileage program toward earning status, I can easily get United silver status (probably by mid year), will likely make United gold status, and depending on how possible international trips go I might even make it all the way to United platinum status though that's a stretch.

All those United miles will help with that, and so will the chase UR points as they have a United transfer partner. But this leaves me without a good redemption option for all those MR points I have sitting around.

Right now I'm getting about half of a little more the annual fee of the platinum back in what I consider real benefits, ie, stuff I'd use anyway:

- I'm maxing out the equinox benefit, and I'd get that even if I didn't use the card

- I'm actually benefiting significantly from the no-fee venmo transfers (I refuse to trust venmo with my bank account information) to do things like send money to my mom

- I'm sort of vaguely forcing use of some of the other benefits, like I find some random thing to buy from Saks every six months, have signed up for Walmart+ but don't really use it, etc. I guess the Uber thing, though I usually use it on Uber eats and probably spend more on their fees than I save with the monthly credit

- the airline credit went mostly to United travel bank last year, I guess I could do that again this year, I guess. Though given how many United miles I have, god only knows when I'll actually use travel bank funds.

- because there's no centurion lounge in ohare, and I use a lot of United lounges now, I very rarely use Amex lounge access---pretty much only if I'm in an airport with a much nicer centurion lounge (like SFO)

- I hate the hotel benefit. The hotels that are eligible for it tend to be much more expensive than I'd usually book for myself, so I basically lose money trying to use it.

so I guess my options are:

1) keep everything as is, decide I'm getting enough value from the platinum, try to get a retention offer, and maybe try to use the MR points on a star alliance partner booked flight toward the end of the year after I've already gotten as far in United status as possible?

2) double down aggressively and get a Schwab account and the Schwab platinum too (?!!? Can you get the signup bonus on that one even if you've already gotten the vanilla platinum bonus) in order to have a semi-decent outlet for converting all those MR points into money, do that, and then maybe keep the Schwab one but not the vanilla

3) downgrade and/or get a different Amex to keep the MR points, let the platinum go

What would you do in my situation?
