Delay causes
Why AA 2345 runs late
Carriers report a reason for every delay minute they cause, in five DOT categories. The split below is by minutes, not by number of flights, so a handful of very long weather delays weighs as much as many short ones. It covers 6,692 reported delay minutes.
- 38%Late-arriving aircraft
- 36%Carrier
- 18%National Airspace System
- 8%Extreme weather
- 0%Security
38% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. Across 6,692 reported delay minutes here, that single category outweighs weather by 5 to one. The split is drawn from 6,692 delay minutes reported on AA 2345.
Cancellations sit at 2.48% against a national 1.89%, which is ordinary. Diversions add another 0.00%.
Connections and routes
What a delay on this flight costs
10.2% of arrivals land a full hour or more behind schedule, against 8.3% nationally. Ninety minutes is the honest minimum for a connection here, and two hours if the onward flight is on a separate ticket.
The 612 miles between these two airports put this in the middle of the US network, around two and a half to three hours of block time. That is enough cruise to absorb a ten-minute late pushback and not enough to absorb thirty.
Every one of the 363 flights under AA 2345 in the data flew ORD to DCA. The number was not reused on any other city pair, which makes this a clean record of one route.
One caution: this is a thin sample. 363 flights over twelve months is enough to clear this site's floor but not enough to pin the rate down tightly, and a single bad week moves it by more than a point. Treat the grade as a rough reading.
What to do with this
Booking AA 2345
For a booking, read AA 2345 as 76.8% on time with 2.48% cancelled over 363 flights. Those are rates from the past twelve months, not a forecast for any particular day.
