Welcome!

Here's a softball comment... it'd be great if the list of Pre-√ participating airports and checkpoints had some indication of hours of operation again (like it used to), as I would sometimes base flight decisions on them. For example, Pre-√ at JFK T5 (jetBlue) used to be (and maybe still is) only available from 6-9am. If that were still true and I had to book a flight later in the day, I'd probably pick a different airline. Even just an indication of which are "full time" and which are "peak" would help.

Unrelatedly, the creeping of AIT into Pre-√ could be a concern. It seems reasonable for self-selection (eg: the medical scenario) or secondary, but I've seen the "random" WTMD beep go a bit out of control sometimes (to the point where TSOs were even commenting about it), and in that kind of scenario the Pre-√ line starts to look a lot like the regular line...
