HYA to IAD questions
Is HYA–IAD running on time right now?
Smooth skies ahead. Both endpoints currently score the same, route health score 100/100. The airports section above carries the live status and delay window at both ends.
How long is the flight from HYA to IAD?
Great-circle distance is 679 km. With typical jet cruise speed plus taxi, climb and descent, expect roughly 78–88 min gate-to-gate on this route.
How often does HYA–IAD fly?
Jet Linx Aviation runs the route with about 1 flight a week (wed). 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 HYA and arrival-side delay at IAD, 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.
