“Get there two hours early” is only the last line of the plan. Pick your airport and work backward from boarding — through security, parking, and the drive — to the moment you should start packing.

Each page opens by asking how you’re getting there — parking, getting dropped off, rideshare, or transit where a real train runs — and whether you’re checking bags. The answers fill in a plan that ends at boarding and starts at “final pack & check,” with defaults tuned to that airport: how long security tends to run, whether parking involves a train, how far the gates are. Tap the boarding time or any duration and the whole chain recomputes backward.
The defaults are starting points, not forecasts. Your drive, your terminal, and your Tuesday are all editable — the point is that once the numbers are yours, the leave-by time and the start-packing time fall out of the arithmetic instead of out of optimism.
Not flying? The leave time calculator does the same math for any deadline, and the pre-flight routine covers the morning-of in more detail.
