BKK to LHW questions

Is BKK–LHW running on time right now?

Mostly on schedule. The departure side at BKK is the weaker end, route health score 72/100. The airports section above carries the live status and delay window at both ends.

How long is the flight from BKK to LHW?

Great-circle distance is 2,555 km. With typical jet cruise speed plus taxi, climb and descent, expect roughly 210–249 min gate-to-gate on this route.

What does the route health score measure?

A blend of departure-side delay at BKK and arrival-side delay at LHW, 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.
