If you flew out of George Bush Intercontinental Airport in November, your flight was probably on time.
- 80% of domestic flights from IAH departed on time in November 2022, per the latest Bureau of Transportation Statistics data.
- That's compared to the national rate of 81%.
The big picture: At the national level, airlines performed admirably throughout the fall of 2022, with on-time departure rates at or above 80% between September and November.
- That was up significantly from the summer, when staff shortages and foul weather combined to muck up the complex, interconnected web that is the air travel system.
Zoom out: Across the cities with Axios Local newsrooms, the Washington, D.C. area's Dulles International Airport had the best on-time performance in November 2022, at 88%.
- Denver — where brutal storms tend to snarl wintertime operations — had the lowest, at 76%.
Yes, but: This dataset doesn't include December's meltdown at Southwest Airlines, which led to thousands of cancellations and delays at that carrier nationwide.
- Expect those delays to show up in the next data release, where they'll almost assuredly drag down the systemwide numbers.
Be smart: Because airlines' systems and routes are so interconnected, problems at one airport or in one region tend to cascade across the country.
- Foul weather in, say, Chicago can mean delays in Houston, because planes get stuck and can't make their next planned leg.
The bottom line: Generally speaking, on-time performance tends to dip in the summer (thanks to thunderstorms and the vacation rush) and winter (due to blizzards and holiday crowds) and improve in the spring and fall.
