American on PHX to GEG sits in the middle of the pack with a C+. Close to three flights in four arrive on time by the DOT's definition, 3 points worse than the national rate of 77.3%. The late ones land a little over an hour behind schedule. That rests on 591 flights, with a median arrival 4 minutes early.
The US average over the same twelve months is 77.3%, 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.

Carrier by carrier
American against every carrier on PHX to GEG
American flew 591 of the 1,264 flights on PHX to GEG, about 47% of it. Its 74.4% on time is about level with the route as a whole at 73.9%. Ranked by on-time rate it is first of four carriers on the route, where the range runs from American at 74.4% 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 591 flights.
- 5am–8am—
- 8am–11am44 flights68.2%
- 11am–2pm314 flights76.1%
- 2pm–5pm2 flights—
- 5pm–8pm10 flights—
- 8pm–5am221 flights73.5%
Scale runs 60% to 80%. Rows with fewer than 30 flights show a dash.
The best window here is not the first bank but the 11am–2pm slot at 76.1% on time, ahead of 8am–11am at 68.2%. 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 314 flights scheduled in it.
Across the year
American on PHX to GEG through the year
August is the worst month at 60.5% on time, 28 points below February, the best at 88.6%. Summer afternoon convection and peak-season schedules land on the same weeks every year, so this is a pattern you can book around rather than a run of bad luck. July was the busiest month here, with 61 flights.
Across the week, Tuesday is the strongest day at 85.7% on time and Sunday the weakest at 67.0%, a spread of 19 points.

The worst days
Worst days for American on PHX to GEG
The latest arrival of the period was on 24 May 2026, 6 hours 15 minutes behind schedule; most of its delay minutes were filed as a late-arriving aircraft. The same cause led on three of the five worst days.
| Date | Arrived late by | Largest filed cause |
|---|---|---|
| 24 May 2026 | 6 hours 15 minutes | Late-arriving aircraft |
| 25 January 2026 | 5 hours 28 minutes | Carrier |
| 2 August 2026 | 5 hours 6 minutes | Carrier |
| 15 March 2026 | 4 hours 37 minutes | Late-arriving aircraft |

Delay causes
Why American runs late on this route
Late-arriving aircraft accounts for 60% of the 11,000 delay minutes carriers reported here, and the remaining four split what is left.
- 60%Late-arriving aircraft
- 31%Carrier
- 8%National Airspace System
- 0%Security
- 0%Extreme weather
60% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. Across 11,000 reported delay minutes here, that single category outweighs weather by 60 to one. The split is drawn from 10,778 reported delay minutes.
Cancellations are rare at 0.34%, below the national 1.89% 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
10.9% 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 1,020 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.
The return leg is a different operation and performs like one: it runs 83.5% on time across 591 flights, 9 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 9 points of difference.
One caution: this is a thin sample. 591 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. 591 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 74.4% headline is the most reliable number on the page; the hour and month splits below it are built on a few dozen flights each. 589 completed flights over 12 months sit behind that.
