Delay causes
Why AA 2574 runs late
Carrier accounts for 91% of the 11,000 delay minutes carriers reported here, and the remaining four split what is left.
- 91%Carrier
- 5%Late-arriving aircraft
- 4%National Airspace System
- 0%Extreme weather
The largest share of delay minutes, 91%, falls under carrier control: crew scheduling, maintenance, fuelling, baggage. It accounts for 10,000 of the 11,000 delay minutes reported here. The split is drawn from 11,137 delay minutes reported on AA 2574.
Cancellations sit at 1.63% against a national 1.89%, which is ordinary. Diversions add another 0.33%.
Connections and routes
What a delay on this flight costs
9.0% 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 1,262 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 two other city pairs in the data, including PHX to SBP (37) and DFW to TPA (1), but none flew often enough under AA 2574 to report a rate for. Carriers move flight numbers between routes, so the figures on this page apply to STL to PHX only.
One caution: this is a thin sample. 307 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 2574
For a booking, read AA 2574 as 86.0% on time with 1.63% cancelled over 307 flights. Those are rates from the past twelve months, not a forecast for any particular day.
