CEI to SIN questions
Is CEI–SIN 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 CEI to SIN?
Great-circle distance is 2,116 km. With typical jet cruise speed plus taxi, climb and descent, expect roughly 179–211 min gate-to-gate on this route.
How often does CEI–SIN fly?
Scoot runs the route with about 3 flights a week (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 CEI and arrival-side delay at SIN, 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.
