How the St Louis to Beijing route actually runs
Pro Flight Search records official board updates for nonstop STL to PEK flights through the day: schedules, estimates, gate pushes and actual departures. The verdict above comes from operated flights, so it reflects what this route does rather than what the timetable promises.

STL to PEK questions
Is STL–PEK running on time right now?
Mostly on schedule. The departure side at STL is the weaker end, route health score 71/100. The airports section above carries the live status and delay window at both ends.
How long is the flight from STL to PEK?
Great-circle distance is 10,832 km. With typical jet cruise speed plus taxi, climb and descent, expect roughly 795–958 min gate-to-gate on this route.
How often does STL–PEK fly?
Jet Linx Aviation runs the route with about 1 flight a week (mon). 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 PEK, 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.
