Compare airports
Put two to four airports side by side: the same metrics, from the same source, each measured over its own real reporting period.
IAH vs HOU
Each column is that side's own numbers, over that side's own real reporting period.
HOU is clearly ahead on 3 of 4 rates, IAH on 1.
A check mark and green mark the better figure in a row (higher for on-time rates, lower for delays and cancellations) when the gap is larger than chance would produce: a two-proportion test on each side’s flight count, at about 95% confidence. “Too close to call” rows differ by less than that. Average and median delay carry no sample-error estimate here, so they are marked by the printed figure alone.
IAH (Houston): July 2023 – July 2026 · HOU (Houston): July 2023 – July 2026
Source: FlyerIntel analysis of US DOT BTS data · Two entities can cover different real windows of history — a newer carrier, a discontinued route, an airport that only recently cleared the sample floor. The period above is what each side actually has, not a shared assumption.
Month by month
On-time arrival for each month, on one shared calendar, so a steady gap looks different from one bad season.
