ICN to PRG questions

Is ICN–PRG running on time right now?

Smooth skies ahead. The departure side at ICN is the weaker end, route health score 82/100. The airports section above carries the live status and delay window at both ends.

How long is the flight from ICN to PRG?

Great-circle distance is 8,236 km. With typical jet cruise speed plus taxi, climb and descent, expect roughly 611–736 min gate-to-gate on this route.

How often does ICN–PRG fly?

2 carriers operate this route, around 7 flights a week between them. Compare carrier days and times in the airline list above.

What does the route health score measure?

A blend of departure-side delay at ICN and arrival-side delay at PRG, 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.
