For better or worse, I think I used all my ConnectionSaver karma before the official announcement and rollout of the frontend:
55 minute connect at ORD to the last flight of the day, was going to be F to B. Arrived 35 min late due to late inbound, mechanical issue needing a writeup, and higher than forecast headwinds. Gates swapped to be adjacent in C, and even after waiting for my gate check I boarded at T-14m (and got the CPU when I did). Someone I know at HQ confirmed it was the new systems doing.
