With Pre-Check, I'm usually through security in the US pretty quickly. But I hate feeling rushed or worrying about being late so I still normally leave plenty of time and, as you say, can usually hang out in a lounge and/or get a meal so it's pretty comfortable.

I worked for a guy once and when we traveled together (pre-9/11) he'd get a cab from our downtown location to the airport planning to arrive 30 minutes or whatever before the flight. Drove me crazy.
