The Buffer That
Pays For ItselfA turnaround modeled as what it actually is — a chain of dependent tasks, run thousands of times

Every minute of schedule buffer or ground-crew staffing has a cost. Every minute short of it risks a delay that cascades into the next rotation. Move the levers below and watch on-time probability respond — the same trade-off a station manager weighs every time next season's schedule or headcount gets planned.

The operator's read — draft, mine to rewrite

A 55-minute turn sounds like plenty until you watch it happen: deboarding runs a little long, catering's still buttoning up the aft galley, and boarding — the one step that can't start until the cabin's actually ready — is now racing a closing gate. That's not bad luck. It's math, and it's the same math every time.

The useful question was never "add more buffer" or "add more staff" — both cost money a station doesn't have unlimited amounts of. It's which few minutes actually move the number. This model is built to answer exactly that, station by station, before the schedule ever gets built.

Illustrative model built on typical industry turnaround-time benchmarks — deboarding, cabin clean, catering, fueling, baggage/cargo and boarding — not any single airline's or airport's actual data. Ground-crew and gate-agent staffing move cleaning, baggage and boarding pace; deboarding, catering and fueling are held fixed. Every setting runs a fresh 2,500-trial Monte Carlo simulation live in your browser.
