XIY to DMK questions
Is XIY–DMK running on time right now?
Smooth skies ahead. Both endpoints currently score the same, route health score 100/100. The airports section above carries the live status and delay window at both ends.
How long is the flight from XIY to DMK?
Great-circle distance is 2,426 km. With typical jet cruise speed plus taxi, climb and descent, expect roughly 201–238 min gate-to-gate on this route.
How often does XIY–DMK fly?
Thai Lion Air runs the route with about 3 flights a week (mon, thu, sat). 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 XIY and arrival-side delay at DMK, 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.
