How the Frankfurt am Main to Ulaanbaatar route actually runs

FRA to UBN questions
Is FRA–UBN running on time right now?
Some delays possible. The departure side at FRA is the weaker end, route health score 66/100. The airports section above carries the live status and delay window at both ends.
How long is the flight from FRA to UBN?
Great-circle distance is 6,640 km. With typical jet cruise speed plus taxi, climb and descent, expect roughly 499–599 min gate-to-gate on this route.
How often does FRA–UBN fly?
MIAT Mongolian Airlines runs the route with about 4 flights a week (sun, mon, wed, fri). 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 FRA and arrival-side delay at UBN, 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.
