How the Beijing to Attock route actually runs
Pro Flight Search records official board updates for nonstop PEK to ISB 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.

PEK to ISB questions
Is PEK–ISB running on time right now?
Mostly on schedule. The departure side at PEK is the weaker end, route health score 76/100. The airports section above carries the live status and delay window at both ends.
How long is the flight from PEK to ISB?
Great-circle distance is 3,921 km. With typical jet cruise speed plus taxi, climb and descent, expect roughly 307–366 min gate-to-gate on this route.
How often does PEK–ISB fly?
Air China runs the route with about 3 flights a week (sun, tue, 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 PEK and arrival-side delay at ISB, 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.
