How the New York to Nantucket route actually runs
Pro Flight Search records official board updates for nonstop LGA to ACK flights through the day: schedules, estimates, gate pushes and actual departures. The verdict above comes from operated flights, so it reflects what this route does rather than what the timetable promises.

LGA to ACK questions
Is LGA–ACK 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 LGA to ACK?
Great-circle distance is 324 km. With typical jet cruise speed plus taxi, climb and descent, expect roughly 53–58 min gate-to-gate on this route.
How often does LGA–ACK fly?
JetBlue Airways runs the route with about 4 flights a week (sun, mon, 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 LGA and arrival-side delay at ACK, 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.
