ORF to IAH questions
Is ORF–IAH running on time right now?
Smooth skies ahead. The departure side at ORF is the weaker end, route health score 93/100. The airports section above carries the live status and delay window at both ends.
How long is the flight from ORF to IAH?
Great-circle distance is 1,930 km. With typical jet cruise speed plus taxi, climb and descent, expect roughly 166–195 min gate-to-gate on this route.
How often does ORF–IAH fly?
United Airlines 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 ORF and arrival-side delay at IAH, 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.
