I often fly out of a smaller airport in Upstate NY. For a morning flight, my routine is to set my alarm for 1:15 before the flight takes off. I get up, pack, and am out the door about with about an hour to go. I get to the airport with about 45 minutes to go, and arrive at the gate in time to wait 20 minutes to actually start the boarding process. With precheck, most airports aren't much worse, other than the uncertainty of transport in. I've never had precheck take me longer than about 10 minutes in security. So as long as I'm not checking a bag, it's still pretty reasonable to arrive 45min before departure.
