ANC to IAH questions
Is ANC–IAH running on time right now?
Smooth skies ahead. The departure side at ANC is the weaker end, route health score 88/100. The airports section above carries the live status and delay window at both ends.
How long is the flight from ANC to IAH?
Great-circle distance is 5,248 km. With typical jet cruise speed plus taxi, climb and descent, expect roughly 400–480 min gate-to-gate on this route.
How often does ANC–IAH fly?
Cathay Pacific runs the route with about 3 flights a week (sun, thu, 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 ANC 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.
