That time of year is coming, seeking advice on consolidating card accounts:

Point earners currently on hand
UA Exp
old Ink Bold
new Ink Bold
Chase SP
CO PP
Amex Biz Gold
Amex PRG
Amex Plat
Citi AA Visa
Citi AA "amex"
Citi AA Biz

Barring any decent retention offers, any reason not to do the following?

Drop
Citi AA "amex" & Visa - wait the 18+ out
Amex PRG
Ink Bold 1
either UA Exp or CO PP

Keep
Amex Plat for bennies
Ink Bold 2 for category bonuses
SP for dining

On the fence about
Amex Biz Gold's future?
Hopefully Citi AA Biz can still be churned?
Ink Bold 1 above - possible value for threshold bonuses?
CO PP for lounge and FEQM for less than Plat status.

My focus is clearly on the 3 US majors and their partners.
I value long haul awards and access benefits most of all.
With that in mind, I do not value hotel cards, and I personally wouldnt waste a pull on C1

Advice on any major flaws with the above or large opportunities I'm missing?
