How it is worked out
Working back from departure: boarding starts about 40 minutes before, the walk to the gate takes about 15, and security takes the top of its usual band for your airport at the hour you would reach it. A checked bag adds 20 minutes at the counter, parking adds 10, and your drive goes on the front.
Security times are typical for the weekday and hour, worked out from public screening counts at 426 US airports. They are not a live measurement of the line, and a holiday or a storm will run longer. The worst hours at airport security has the method and the limits.
This is an estimate. Check the airline’s app for the boarding time before you change plans.
