Departure window
The best time of day to leave HOU in November
Departure time matters more here than the choice of carrier. The gap between the best and worst window is 25 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–8am577 flights91.2%
- 8am–11am930 flights90.8%
- 11am–2pm819 flights81.7%
- 2pm–5pm721 flights79.7%
- 5pm–8pm716 flights72.0%
- 8pm–5am789 flights65.8%
Scale runs 55% to 95%. Rows with fewer than 30 flights show a dash.
Book the early departure. Flights leaving between 5am–8am arrive on time 91.2% of the time, against 65.8% for the overnight window. That is 25 points of difference for no extra money, and it comes from the same aircraft having had no earlier flight to fall behind on. The 8am–11am window is the busiest, with 930 flights scheduled in it.
Across the week, Wednesday is the strongest day at 92.8% on time and Monday the weakest at 70.7%. 22 points is a smaller lever than departure hour, but it is free.

Delay causes
What held HOU up in November
One category carries most of the weight here. Late-arriving aircraft accounts for 52% of the 51,000 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.
- 52%Late-arriving aircraft
- 27%Carrier
- 20%National Airspace System
- 1%Extreme weather
- 0%Security
52% 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 51,000 reported delay minutes here, that single category outweighs weather by 40 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 51,140 reported delay minutes.
Cancellations sit at 2.20% against a national 2.49%, which is ordinary. Diversions add another 0.09%.
6.8% of arrivals land an hour or more late, close to the national 7.8%. 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 about an hour, which a normal layover absorbs.
