October next to OAK's other months

Against OAK's own year, October ran level with the twelve-month rate of 79.5%, which makes it number seven of twelve months, best first. Cancellations were unusually low for OAK in October, at 0.25% against 0.64% across the year. Either side of it, September ran 82.4% on time and November 81.6%, so a trip moved by a few weeks would have landed in a better stretch.

Departure window

The best time of day to leave OAK in October

Departure time matters more here than the choice of carrier. The gap between the best and worst window is 32 points, against half a point between the best and worst carrier. Each bar is the on-time rate for flights scheduled inside that window.

5am–8am595 flights95.2%
8am–11am481 flights88.3%
11am–2pm520 flights81.4%
2pm–5pm447 flights65.8%
5pm–8pm403 flights72.3%
8pm–5am325 flights63.6%

Scale runs 55% to 100%. Rows with fewer than 30 flights show a dash.

The 8pm–5am window is where this operation falls apart: 63.6% on time, against 95.2% for the 5am–8am slot. By evening the aircraft flying these rotations have absorbed a full day of small delays and there is no slack left to recover in. The 5am–8am window is the busiest, with 595 flights scheduled in it.

Across the week, Saturday is the strongest day at 91.4% on time and Sunday the weakest at 70.4%. 21 points is a smaller lever than departure hour, but it is free.

Delay causes

What held OAK up in October

One category carries most of the weight here. Late-arriving aircraft accounts for 50% of the 29,000 delay minutes carriers reported, and the remaining four split what is left. The split is by minutes rather than by flights, so a few very long delays count for as much as many short ones.

Late-arriving aircraft

36%
National Airspace System

Extreme weather

Security
0%

50% 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 29,000 reported delay minutes here, that single category outweighs weather by 38 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 28,952 reported delay minutes.

Cancellations are rare at 0.25%, 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.

5.1% 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 roughly 50 minutes, which a normal layover absorbs.
