HEL to LIS questions
Is HEL–LIS running on time right now?
Smooth skies ahead. The departure side at HEL is the weaker end, route health score 94/100. The airports section above carries the live status and delay window at both ends.
How long is the flight from HEL to LIS?
Great-circle distance is 3,364 km. With typical jet cruise speed plus taxi, climb and descent, expect roughly 267–318 min gate-to-gate on this route.
How often does HEL–LIS fly?
Finnair runs the route with about 7 flights a week (daily). 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 HEL and arrival-side delay at LIS, 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.
