These figures cover 279 flights between September 2025 and August 2026. The median arrival is 4 minutes early, which is the part an average hides: most flights here are fine, and the on-time rate is decided by a tail of badly late ones. On-time means under 15 minutes late, the DOT's own threshold.

Across the year
AS 746 quarter by quarter
AS 746 did not run the same all year. Its best quarter was Apr–Jun 2026 at 86.1% on time and its weakest Jul–Sep 2026 at 60.9%, a swing of 25 points on roughly 70 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.

By weekday, AS 746 did best on Saturday at 85.3% on time and worst on Friday at 65.0%. Each day rests on about 40 flights, so a gap of 20 points is worth noticing but could still narrow in another year.

Share of 276 completed flights by arrival against schedule.
14 of 60 late departures made up the time and arrived on time, 23% of them. In the other direction, 19 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 746
The latest arrival of the period was on 9 November 2025, 3 hours 28 minutes behind schedule; most of its delay minutes were filed as national airspace system delay. The five worst days are spread across November, April, January and July, with no single month standing out.
| Date | Arrived late by | Largest filed cause |
|---|---|---|
| 9 November 2025 | 3 hours 28 minutes | National Airspace System |
| 3 April 2026 | 3 hours 7 minutes | Carrier |
| 5 November 2025 | 3 hours 6 minutes | National Airspace System |
| 5 January 2026 | 3 hours 6 minutes | Carrier |
| 27 July 2026 | 2 hours 29 minutes | Late-arriving aircraft |
Delay causes
Why AS 746 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 3,434 reported delay minutes.
- 37%National Airspace System
- 33%Late-arriving aircraft
- 31%Carrier
37% of delay minutes are charged to the National Airspace System: air traffic volume, runway configuration, ground stops. No carrier can price its way out of that, which is why airport choice moves the number here more than carrier choice does. That is 1,263 minutes out of 3,434, against a national NAS share of 21%. The split is drawn from 3,434 delay minutes reported on AS 746.
Cancellations are rare at 0.72%, 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
6.5% 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 55 minutes, which a normal layover absorbs.
The 1,010 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 two other city pairs in the data, including SEA to PHX (13) and PHX to SEA (8), but none flew often enough under AS 746 to report a rate for. Carriers move flight numbers between routes, so the figures on this page apply to PDX to PHX only.
One caution: this is a thin sample. 279 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 746
