Historical statistics for July 2025 to June 2026, not live status. For today’s AA 2523, check with American Airlines.

AA 2523 lands a B, 2 points better than the national rate of 77.6%. About one flight in five arrives 15 minutes late or worse, and those flights are late by a little over an hour on average. That is a workable record, not a spotless one. That rests on 262 flights, with a median arrival 5 minutes early.

These figures cover 262 flights between July 2025 and June 2026. Beyond the headline rate, 8.3% 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 2523 flies

AA 2523 flies PHL to TPA without a single fixed slot. Its most common scheduled departure was 08:54, used on 31 of 262 flights, with 08:15 (29 flights) and 08:46 (28 flights) next. Carriers retime flights through the season, so the rates here blend slightly different positions in the aircraft's day.

Scale runs 0% to 100%. Rows with fewer than 30 flights show a dash.

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

A 08:54 departure sits in the 8am–11am window. Across every US flight scheduled in that window the on-time rate is 84.1%, and AA 2523 runs 5 points worse at 79.1%. Early departures usually start with an aircraft that has not flown yet that day, which is most of why the window does well.

Against the route

AA 2523 next to PHL to TPA

Across the year

AA 2523 quarter by quarter

Quarter by quarter AA 2523 held fairly steady: 78.7% in Jul–Sep 2025, 85.1% in Oct–Dec 2025 and 75.3% in Jan–Mar 2026. A spread of 10 points is about what a sample of this size moves on its own, so the annual figure is a fair summary.

By weekday, AA 2523 did best on Wednesday at 94.4% on time and worst on Saturday at 57.1%. Each day rests on about 37 flights, so a gap of 37 points is worth noticing but could still narrow in another year.

Delay causes

Why AA 2523 runs late

One category carries most of the weight here. Carrier accounts for 42% of the 4,274 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
    42%
  • Late-arriving aircraft
    41%
  • National Airspace System
    17%

41% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. That is a cascade, and cascades start small and grow through the day. Across 4,274 reported delay minutes here, that single category outweighs weather by 41 to one. It is the strongest argument for booking the first departure of the morning, when the aircraft has been sitting at the gate overnight with nothing to inherit. The split is drawn from 4,274 delay minutes reported on AA 2523.

Cancellations sit at 2.29% against a national 1.81%, which is ordinary. Diversions add another 0.76%.

Connections and routes

What a delay on this flight costs

8.3% of arrivals land an hour or more late, close to the national 8.1%. That is the figure that decides a connection, and it says a 60 to 75 minute layover is reasonable here while anything under 45 minutes is a bet. Most delays on this route last a little over an hour, which a normal layover absorbs.

The 920 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 five other city pairs in the data, including TPA to PHL (193), SEA to ORD (41) and ORD to SEA (41), but none flew often enough under AA 2523 to report a rate for. Carriers move flight numbers between routes, so the figures on this page apply to PHL to TPA only.

One caution: this is a thin sample. 262 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 2523

For a booking, read AA 2523 as 79.1% on time with 2.29% cancelled over 262 flights. Those are rates from the past twelve months, not a forecast for any particular day.
