These figures cover 333 flights between September 2025 and August 2026. On-time means an arrival less than 15 minutes after the scheduled gate time, the same threshold the Department of Transportation uses in its own reports. Cancelled and diverted flights are excluded from the on-time rate and counted separately, which is why the cancellation column matters on its own.

Across the year
AS 744 quarter by quarter
AS 744 did not run the same all year. Its best quarter was Jul–Sep 2025 at 86.7% on time and its weakest Jul–Sep 2026 at 55.7%, a swing of 31 points on roughly 67 flights a quarter. The twelve-month rate averages over that, so if you are flying in a weak quarter the quarter's own figure is the better guide.

- Oct–Dec 202589 flights73.0%
- Jan–Mar 202683 flights84.3%
- Apr–Jun 202669 flights76.8%

Scale runs 45% to 90%.
By weekday, AS 744 did best on Saturday at 84.8% on time and worst on Monday at 66.0%. Each day rests on about 48 flights, so a gap of 19 points is worth noticing but could still narrow in another year.

Share of 332 completed flights by arrival against schedule.
25 of 89 late departures made up the time and arrived on time, 28% of them. In the other direction, 20 flights left on time yet arrived 15 minutes late or more, so that delay built up after pushback: in the air, in a holding pattern or on the ground at PHX.
The worst days
Worst days for AS 744
The latest arrival of the period was on 23 October 2025, 6 hours behind schedule; most of its delay minutes were filed as carrier-caused (crew, maintenance, fuelling, baggage). The same cause led on three of the five worst days.
| Date | Arrived late by | Largest filed cause |
|---|---|---|
| 23 October 2025 | 6 hours | Carrier |
| 9 November 2025 | 3 hours 24 minutes | National Airspace System |
| 25 July 2026 | 2 hours 27 minutes | Carrier |
| 23 November 2025 | 2 hours 6 minutes | Carrier |
| 31 October 2025 | 1 hour 43 minutes | National Airspace System |
Delay causes
Why AS 744 runs late
Carriers report a reason for every delay minute they cause, in five DOT categories. The split below is by minutes, not by number of flights, so a handful of very long weather delays weighs as much as many short ones. It covers 3,951 reported delay minutes.
- 42%Carrier
- 34%National Airspace System
- 24%Late-arriving aircraft
The largest share of delay minutes, 42%, falls under carrier control: crew scheduling, maintenance, fuelling, baggage. It accounts for 1,648 of the 3,951 delay minutes reported here. The split is drawn from 3,951 delay minutes reported on AS 744.
Cancellations are rare at 0.30%, 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 routes
What a delay on this flight costs
5.1% of arrivals land an hour or more late, close to the national 8.3%, so a 60 to 75 minute layover is reasonable here while anything under 45 minutes is a bet. Most delays on this route last roughly 45 minutes, which a normal layover absorbs.
The 1,107 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 same number turns up on one other city pair in the data, including SLC to SEA (21), but none flew often enough under AS 744 to report a rate for. Carriers move flight numbers between routes, so the figures on this page apply to SEA to PHX only.
One caution: this is a thin sample. 333 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 AS 744
For a booking, read AS 744 as 74.7% on time with 0.30% cancelled over 333 flights. Those are rates from the past twelve months, not a forecast for any particular day.
