Planning ahead pays off when something eventually goes wrong at every step.

Late start, traffic, late shuttle, understaffed security, long lines, construction, gate moved to another concourse, gate moved to another concourse - if you put enough buffer time in the schedule, you can still make the flight.

Nailed it. All of those things are outside of my control and completely random. I can only make sure I’ve given myself the flexibility to adapt to them.
