STL to PWK questions
Is STL–PWK running on time right now?
Smooth skies ahead. The departure side at STL is the weaker end, route health score 88/100. The airports section above carries the live status and delay window at both ends.
How often does STL–PWK fly?
Jet Linx Aviation runs the route with about 1 flight a week (thu). Since one carrier owns the route, a single disruption tends to ripple through the day.
What does the route health score measure?
A blend of departure-side delay at STL and arrival-side delay at PWK, computed from rolling delay windows (refreshed every 40 minutes) with a daily-rollup fallback. Current MVFR, IFR, or LIFR endpoint weather caps the score when flight rules can limit throughput. Higher is healthier: 100 means operations are clean at both ends.
