CLE to SAT questions
Is CLE–SAT 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 CLE to SAT?
Great-circle distance is 1,996 km. With typical jet cruise speed plus taxi, climb and descent, expect roughly 171–201 min gate-to-gate on this route.
How often does CLE–SAT fly?
2 carriers operate this route, around 4 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 SAT, 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.
