Historical statistics for July 2025 to June 2026, not live status. For today’s AA 2574, check with American Airlines.

AA 2574 earns a B. More than four flights in five arrive inside the 15-minute window the DOT uses to define an on-time arrival, which puts it 7 points better than the national rate of 77.6%. When something does go wrong the average delay runs about 3.4 hours. That rests on 297 flights, with a median arrival 12 minutes early.

Set against the rest of the country, AA 2574's record is 7 points better than the US average of 77.6%. That gap is worth roughly 70 fewer late arrivals for every thousand flights.

These figures cover 297 flights between July 2025 and June 2026. Beyond the headline rate, 11.0% of arrivals land a full hour or more behind schedule. That is the number that wrecks a connection, and it is not visible in an on-time percentage alone.

Schedule

When AA 2574 flies

AA 2574 flies STL to PHX without a single fixed slot. Its most common scheduled departure was 08:00, used on 84 of 297 flights, with 07:58 (53 flights) next. Carriers retime flights through the season, so the rates here blend slightly different positions in the aircraft's day.

Share of scheduled departures at each local time. Times used on fewer than one flight in ten are not listed.

A 08:00 departure sits in the 8am–11am window. Across every US flight scheduled in that window the on-time rate is 84.1%, and AA 2574 runs level with that at 84.6%. Early departures usually start with an aircraft that has not flown yet that day, which is most of why the window does well.

Across the year

AA 2574 quarter by quarter

Quarter by quarter AA 2574 held fairly steady: 80.8% in Jul–Sep 2025, 84.9% in Oct–Dec 2025, 87.5% in Jan–Mar 2026 and 84.4% in Apr–Jun 2026. A spread of 7 points is about what a sample of this size moves on its own, so the annual figure is a fair summary.

Jan–Mar 202690 flights87.5%

Scale runs 70% to 95%. Rows with fewer than 30 flights show a dash.

By weekday, AA 2574 ranged from 79.5% on Friday to 90.0% on Thursday. With about 42 flights behind each day, a spread of 11 points is inside normal variation, so the day you fly is not worth changing for this flight.

Delay causes

Why AA 2574 runs late

One category carries most of the weight here. Carrier accounts for 79% of the 9,201 delay minutes carriers reported, and the remaining four split what is left. The split is by minutes rather than by flights, so a few very long delays count for as much as many short ones.

Carrier
79%
Late-arriving aircraft
16%
National Airspace System
4%
Extreme weather
1%

The largest share of delay minutes, 79%, falls under carrier control: crew scheduling, maintenance, fuelling, baggage. Unlike weather, that is a management outcome, and it is the category where the gap between two carriers on the same schedule is genuinely earned. It accounts for 7,286 of the 9,201 delay minutes reported here. The split is drawn from 9,201 delay minutes reported on AA 2574.

Cancellations sit at 1.35% against a national 1.81%, which is ordinary. Diversions add another 0.34%.

Connections and routes

What a delay on this flight costs

For anyone connecting, the number to weigh is not the on-time rate but the tail behind it. 11.0% of arrivals land a full hour or more behind schedule, against 8.1% nationally. A 45-minute layover does not survive that, and no amount of walking quickly changes it. Ninety minutes is the honest minimum 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. It is also long enough that the aircraft usually flies three or four legs a day rather than six, which slows how fast delay compounds.

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. 297 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 84.6% on time with 1.35% cancelled over 297 flights. Those are rates from the past twelve months, not a forecast for any particular day.
