Best time of day to fly out of SBA
Time of day matters more at SBA than almost anything else you control. Flights scheduled to leave at 5 a.m. arrived on time 95% of the time; at 9 a.m. it was 69%, a 25-point gap. Taken together, early departures (5–9 a.m.) ran 90% on time against 74% for the evening bank (5–10 p.m.). Early planes usually start the day at the airport, so they haven't had a chance to pick up delays elsewhere. By evening a late inbound aircraft, a crew running out of duty hours or an afternoon thunderstorm can push one late flight into the next. Cancellations cluster too: 10 a.m. departures were cancelled 2.2% of the time, against 1.1% overall.
Hour × month
Combine the two and the spread is wider still. The most reliable combination at SBA was a 5 a.m. departure in April (96% on time); the least, 2 p.m. in April (62%). If you can only move one thing, move the hour. Departure hour usually shifts the odds more than the month does.
Each cell: on-time rate for that departure hour in that calendar month, 2023–2026. Find your travel month, then look along the row for the greenest hour.
Best and worst months
July is the hardest month at SBA, with 78% of flights on time across 2023–2026; September is the best at 86%. Summer (June–August) runs 6 points worse than autumn: heavy schedules, peak loads and afternoon thunderstorms. Cancellations peak in February (2.9% of flights).
Airlines at SBA
United Airlines runs 35% of departures from SBA. Among airlines with at least 1,000 departures here, Delta Air Lines was the most reliable (91% on time) and United Airlines the least (71%), a 20-point difference. On a route where both fly, that difference is worth more than a small fare gap.

Why flights are late at SBA
Airlines report a cause for every flight that arrives 15 or more minutes late. At SBA, 33% of delay minutes came from the air traffic system: air traffic control programs, airport congestion and non-severe weather. Next is late-arriving aircraft at 32%. Of the 99 cancellations, 47% were blamed on weather.
The average taxi from gate to takeoff is 16 minutes, about typical for a large U.S. airport.
Month by month
Over the latest 12 months 80% of SBA departures were on time, against 82% in the 12 months before, a decline of 2 points. The best recent month was February 2026 (86%); the worst, August 2026 (72%).
Worst cancellation days
The worst single day in the past year was Saturday, Jan 3, 2026, when 52% of 25 scheduled departures were cancelled. Days like that are usually a major storm, a system outage or a holiday peak hitting bad weather. No average predicts them, so on a stormy forecast, check your airline's travel waivers.

Tips for flying out of SBA
- Book the earliest departure you can live with. At SBA the 5 a.m. flights do best.
- Traveling in July? Leave extra slack for anything that can't move: cruises, weddings, the last connection of the day.
- Choosing between airlines? Delta Air Lines has the better record here.
- Delayed already? Most delays at SBA come from the air traffic system. If your inbound plane is late, your flight will be too, whatever the board says.
