CLE to BOS questions
Is CLE–BOS running on time right now?
Some delays possible. The departure side at CLE is the weaker end, route health score 56/100. The airports section above carries the live status and delay window at both ends.
How long is the flight from CLE to BOS?
Great-circle distance is 903 km. With typical jet cruise speed plus taxi, climb and descent, expect roughly 94–107 min gate-to-gate on this route.
How often does CLE–BOS fly?
2 carriers operate this route, around 38 flights a week between them. Compare carrier days and times in the airline list above.
What does the route health score measure?
A blend of departure-side delay at CLE and arrival-side delay at BOS, 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.
