If you already hold the AMEX Plat, bennies are equal. To add the Chase Sapphire RESERVE (new, not the old PREFERRED) to your stable, worth considering.
The sign up boner (100k) on the CSR is well worth. The $450 annual may seem daunting initially.
You get a $300 travel credit against the annual fee per calendar year. So, you get $600 against your $450 fee the first actual year. I'm not a shill, just a cheap ass.
Oh yeah.... $100 credit against your TSA or Global Entry app, which you assuredly already have.
Other benefits are equi to AE Plat.
