So my experience.

Weekend travel - far fewer elites than previous. As a PLT I would rarely burn 500 mile carts in the previous few years. Now, I’ve upgraded using certs on most of the last 8 or so trips.

Weekday travel - not anywhere near where it was, but, far heavier on elites than weekends. I’ve done CLT-MEM-CLT a few times in recent weeks, and the upgrade list regularly has 10-15 people on it. Group 3, there’s usually a good 2 dozen people on the plane before me (including F).
