Everyone has their own price elasticity, and it changes over time. As someone who has a Plat, I don’t really see the additional value in the Centurion, and tbh would be hard to motivate myself to put all that much of a percentage of my spend on Amex versus other programs. I also prefer the status of not having a logo that people recognize. It is kinda like how it is embarrassing when I’m flying in business class and friends pass me walking to coach, or that I’d rather have something nicely designed by someone famous than something with gauche trademark like Rimowa or Louis Vittton.
