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

American on PHX to PIT lands a B+, about a point 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 373 flights, with a median arrival 10 minutes early.

The US average over the same twelve months is 77.6%, so there is little to separate American on PHX to PIT from the country as a whole. The variation that matters here is internal: which carrier, and what time of day.

These figures cover 373 flights between July 2025 and June 2026. Beyond the headline rate, 9.2% 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.

Carrier by carrier

American against every carrier on PHX to PIT

American flew 373 of the 812 flights on PHX to PIT, about 46% of it. Its 78.9% on time is 3 points better than the route as a whole, which runs 76.3%. Ranked by on-time rate it is first of three carriers on the route, where the range runs from American at 78.9% to Southwest at 73.2%. One of those carriers flew fewer than 365 flights here, so treat their positions as rough.

Only one carrier clears this site's 365-flight floor here, so there is no comparison to draw. The table below is the full picture.

Departure window

When American runs best on this route

Departure time is the single lever a traveller controls, and it moves the odds more than most people expect. Each bar below is the on-time rate for flights scheduled to leave inside that window, across 373 flights.

There are not enough flights in each departure window to split American's PHX to PIT record by time of day without the percentages moving on noise. The headline rate of 78.9% is the reliable figure here.

Darker means more delays. Figures are on-time percentages.December best, March worst

Delays peak in March, when the on-time rate falls to 67.6%. December is the strongest month at 87.9%. Moving a flexible trip across that boundary buys 20 points. March was the busiest month here, with 34 flights.

Across the week, Tuesday is the strongest day at 86.5% on time and Sunday the weakest at 67.9%. 19 points is a smaller lever than departure hour, but it is free.

Delay causes

Why American runs late on this route

One category carries most of the weight here. Late-arriving aircraft accounts for 70% of the 6,007 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.

  • Late-arriving aircraft
    70%
  • Carrier
    24%
  • National Airspace System
    7%

70% 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 6,007 reported delay minutes here, that single category outweighs weather by 70 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 6,007 reported delay minutes.

Cancellations are rare at 0.54%, below the national 1.81% and low enough to earn the plus on the grade. Roughly one flight in 100 is called off; the risk here is arriving late, not not arriving.

Connections and stage length

What a delay here costs

For anyone connecting, the number to weigh is not the on-time rate but the tail behind it. 9.2% 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.

At 1,814 miles this is transcontinental flying, and long routes get a quiet structural advantage. Scheduled block time on a flight this length carries more padding in absolute minutes, so a twenty-minute late departure often still becomes an on-time arrival. Read the on-time rate here as slightly flattering next to a short-haul route with the same operational quality.

The return leg is a different operation and performs like one: it runs 84.8% on time across 372 flights, 6 points above this direction. Departure banks, aircraft rotations and the congestion at each end all differ, so scoring the two directions together would average away a real 6 points of difference.

One caution: this is a thin sample. 373 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 American on PHX to PIT

Put together: treat all of this as provisional. 373 flights over twelve months is enough to clear this site's floor and not enough to be confident to better than a couple of points. The 78.9% headline is the most reliable number on the page; the hour and month splits below it are built on a few dozen flights each. 370 completed flights over 12 months sit behind that.
