As he says, the standard advice of allowing 2 hours before a domestic flight makes absolutely no sense in today’s world.
The worst part of hearing that advice over and over again is that the rare times they are right you will still ignore them. (I once got an email from Lufthansa to that effect, ignored it as usual and proceeded to arrive at the airport one hour before takeoff as I usually do for within-Schengen flights with no luggage to check in, found out there was some kind of strike at the airport and much much slower queues than usual, and missed my flight.)
I never run into this in the US (even under-construction airports only add ~10 minutes to security lines), but I’ve had it happen a bunch in Europe. The worst was a flight from Dublin to the US, where I didn’t realize I needed to go through (slow) security plus (even slower) US passport control plus another layer of security to get onto the flight. I still made the flight but it was stressful.
