Delay causes
Why AA 1726 runs late
Late-arriving aircraft accounts for 56% of the 7,664 delay minutes carriers reported here, and the remaining four split what is left.
- 56%Late-arriving aircraft
- 34%Carrier
- 9%National Airspace System
- 1%Extreme weather
56% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. Across 7,664 reported delay minutes here, that single category outweighs weather by 38 to one. The split is drawn from 7,664 delay minutes reported on AA 1726.
Cancellations sit at 2.17% against a national 1.89%, which is ordinary. Diversions add another 0.36%.
Connections and routes
What a delay on this flight costs
11.2% 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 977 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.
The same number turns up on four other city pairs in the data, including TPA to ORD (30), ORD to AUS (7) and DFW to LGA (4), but none flew often enough under AA 1726 to report a rate for. Carriers move flight numbers between routes, so the figures on this page apply to AUS to ORD only.
One caution: this is a thin sample. 276 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 1726
For a booking, read AA 1726 as 78.1% on time with 2.17% cancelled over 276 flights. Those are rates from the past twelve months, not a forecast for any particular day.
