How the Medford to Santa Ana route actually runs
Pro Flight Search records official board updates for nonstop MFR to SNA 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.

MFR to SNA questions
Is MFR–SNA 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 MFR to SNA?
Great-circle distance is 1,061 km. With typical jet cruise speed plus taxi, climb and descent, expect roughly 105–121 min gate-to-gate on this route.
How often does MFR–SNA fly?
Allegiant Air runs the route with about 2 flights a week (mon, 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 MFR and arrival-side delay at SNA, 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.
