Historical statistics for October 2025, not live status or a forecast for this year’s October. For today’s conditions at SNA, see live FAA status.

SNA in October lands a B+, 3 points better than the national rate of 79.7%. About one flight in six arrives 15 minutes late or worse, and those flights are late by a little over an hour on average. That is a workable record, not a spotless one. That rests on 3,871 flights, of which Delta Air Lines flew 413 at 86.6% on time.

Delta Air Lines is the most reliable of the five carriers covered here at 86.6% on time across 413 flights.

October next to SNA's other months

Against SNA's own year, October ran about a point better than the twelve-month rate of 81.5%, which makes it number five of twelve months, best first. Cancellations were unusually low for SNA in October, at 0.59% against 1.09% across the year. Either side of it, September ran 84.7% on time and November 80.8%, so this month sits in line with its neighbours.

Departure window

The best time of day to leave SNA in October

Departure time matters more here than the choice of carrier. The gap between the best and worst window is 15 points, against 8 points between the best and worst carrier. Each bar is the on-time rate for flights scheduled inside that window.

  • 5am–8am602 flights92.6%
  • 8am–11am772 flights87.1%
  • 11am–2pm882 flights81.1%
  • 2pm–5pm653 flights78.2%
  • 5pm–8pm682 flights78.0%
  • 8pm–5am280 flights79.0%

Scale runs 70% to 100%. Rows with fewer than 30 flights show a dash.

Book the early departure. Flights leaving between 5am–8am arrive on time 92.6% of the time, against 78.0% for the evening window. That is 15 points of difference for no extra money, and it comes from the same aircraft having had no earlier flight to fall behind on. The 11am–2pm window is the busiest, with 882 flights scheduled in it.

Across the week, Saturday is the strongest day at 87.6% on time and Sunday the weakest at 74.5%. 13 points is a smaller lever than departure hour, but it is free.

Carrier by carrier

Which airlines ran best at SNA in October

The choice of carrier is not cosmetic here. Delta Air Lines arrives on time 86.6% of the time; SkyWest Airlines manages 78.9%. Sample sizes sit next to every figure, because a two-point gap across 502 flights means less than a ten-point one.

Delay causes

What held SNA up in October

Carriers report a reason for every delay minute they cause, in five DOT categories. The split below is by minutes, not by number of flights, so a handful of very long weather delays weighs as much as many short ones. It covers 48,000 reported delay minutes.

  • Late-arriving aircraft
    39%
  • Carrier
    34%
  • National Airspace System
    24%
  • Extreme weather
    2%
  • Security
    0%

39% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. That is a cascade, and cascades start small and grow through the day. Across 48,000 reported delay minutes here, that single category outweighs weather by 18 to one. It is the strongest argument for booking the first departure of the morning, when the aircraft has been sitting at the gate overnight with nothing to inherit. The split is drawn from 48,213 reported delay minutes.

Cancellations are rare at 0.59%, below the national 0.53% and low enough to earn the plus on the grade. Roughly one flight in 100 is called off; the risk here is arriving late, not not arriving.

5.5% of arrivals land an hour or more late, close to the national 6.3%. That is the figure that decides a connection, and it says a 60 to 75 minute layover is reasonable here while anything under 45 minutes is a bet. Most delays on this route last a little over an hour, which a normal layover absorbs.

What to do with this

Flying from SNA in October

For a October trip through SNA: expect 82.9% on time and 0.59% cancelled, going by October 2025. The 5am–8am window was the strongest part of the day.
