Will your connection be tight enough?
Layovers at BWI after arriving from PIT.
| Connection time | Chance of missing | Reads as |
|---|---|---|
| 30 min | 28% | High risk |
| 45 min | 13% | Some risk |
| 60 min | 7.5% | Some risk |
| 90 min | 3.7% | Low risk |
| 120 min | 2.1% | 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 1.17% of the time and diverts 0.12% of the time, which a late arrival never shows up in.
Chance of missing is the share of 3,283 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 22 minutes late (90th-percentile gate arrival delay), over 3,326 operations.
