Each comparison pools the flights of other routes, with this route’s own left out. Similar length means within 15% of this route’s 1,090 miles, with at least 5 such routes. A bucket is set against the most comparable group that has enough flights: similar length, then the same origin (at least 3 routes), then all other routes. Hours, weekdays and months appear only where both sides have 120 completed flights, and airlines where both have 600. The gap must be at least 2 points and 2 standard errors, and only the largest gap each way is kept per measure. These are differences in the flights counted, not causes.

Will your connection be tight enough?
Layovers at LAS after arriving from AUS.
| Connection time | Chance of missing | Reads as |
|---|---|---|
| 30 min | 42% | Likely to miss |
| 45 min | 23% | High risk |
| 60 min | 15% | High risk |
| 90 min | 7.3% | Some risk |
| 120 min | 4.3% | Low risk |
This is one leg of a connection. Gate changes and the next flight's own schedule matter too. And a connection can fail before delay is even the question — this route cancels 0.49% of the time and diverts 0.11% of the time, which a late arrival never shows up in.
Chance of missing is the share of 9,666 arrivals on this route that landed later than the connection time less 30 minutes to reach the next gate.
The worst tenth of arrivals on this route land at least 46 minutes late (90th-percentile gate arrival delay), over 9,725 operations.
