BOS to CAP questions
Is BOS–CAP running on time right now?
High disruption likely. The departure side at BOS is the weaker end, route health score 20/100. The airports section above carries the live status and delay window at both ends.
How long is the flight from BOS to CAP?
Great-circle distance is 2,519 km. With typical jet cruise speed plus taxi, climb and descent, expect roughly 208–246 min gate-to-gate on this route.
How often does BOS–CAP fly?
Sunrise Airline 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 BOS and arrival-side delay at CAP, 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.
