Compare airlines
Put two to four airlines side by side: the same metrics, from the same source, each measured over its own real reporting period.
American Airlines vs SkyWest Airlines
Each column is that side's own numbers, over that side's own real reporting period.
SkyWest Airlines is clearly ahead on 4 of 4 rates.
| Metric | American Airlines | SkyWest Airlines |
|---|---|---|
| On-time arrival | 74.8% | 80.4% (better) |
| Cancellation rate | 1.76% | 1.33% (better) |
| Severe delay (60+ min) | 10.0% | 7.9% (better) |
| Average arrival delay | 14 min | 8 min (better) |
| Median arrival delay | -5 min | -7 min (better) |
| Departure on-time | 75.0% | 82.3% (better) |
| Flights analyzed | 3,019,376 | 2,433,643 |
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.

Month by month
On-time arrival for each month, on one shared calendar, so a steady gap looks different from one bad season.
