Historical statistics for July 2025 to June 2026, not live status. For today’s flights, check with American Airlines.
American on PHX to GEG lands a B+, 2 points worse than the national rate of 77.6%. About one flight in four 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 577 flights, with a median arrival 6 minutes early.
The US average over the same twelve months is 77.6%, so there is little to separate American on PHX to GEG from the country as a whole. The variation that matters here is internal: which carrier, and what time of day.

These figures cover 577 flights between July 2025 and June 2026. Beyond the headline rate, 10.2% 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 GEG
American flew 577 of the 1,235 flights on PHX to GEG, about 47% of it. Its 76.1% on time is about level with the route as a whole at 75.5%. Ranked by on-time rate it is first of four carriers on the route, where the range runs from American at 76.1% to Frontier at 68.9%. Two 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 577 flights.
- 5am–8am—
- 8am–11am74 flights71.6%
- 11am–2pm284 flights77.5%
- 2pm–5pm2 flights—
- 5pm–8pm10 flights—
- 8pm–5am207 flights76.3%
Scale runs 65% to 85%. Rows with fewer than 30 flights show a dash.
The best window here is not the first bank but the 11am–2pm slot at 77.5% on time, ahead of 8am–11am at 71.6%. Where the curve peaks mid-day rather than at dawn, the constraint is usually congestion at one end rather than the aircraft's own rotation. The 11am–2pm window is the busiest, with 284 flights scheduled in it.
Across the year
American on PHX to GEG through the year
Delays peak in October, when the on-time rate falls to 63.6%. February is the strongest month at 88.6%. Moving a flexible trip across that boundary buys 25 points. March was the busiest month here, with 60 flights.
Across the week, Tuesday is the strongest day at 87.9% on time and Sunday the weakest at 69.1%. 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 58% of the 10,000 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.
- 58%Late-arriving aircraft
- 34%Carrier
- 6%National Airspace System
- 1%Extreme weather
- 1%Security
58% 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 10,000 reported delay minutes here, that single category outweighs weather by 54 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 10,130 reported delay minutes.
Cancellations are rare at 0.00%, below the national 1.81% and low enough to earn the plus on the grade. Almost no flights are 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. 10.2% 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.
The 1,020 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 return leg is a different operation and performs like one: it runs 83.4% on time across 577 flights, 7 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 7 points of difference.
One caution: this is a thin sample. 577 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 GEG
Put together: treat all of this as provisional. 577 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 76.1% headline is the most reliable number on the page; the hour and month splits below it are built on a few dozen flights each. 577 completed flights over 12 months sit behind that.
