Historical statistics for July 2025 to June 2026, not live status. For today’s AS 744, check with Alaska Airlines.
AS 744 sits in the middle of the pack with a C+. Close to three flights in four arrive on time by the DOT's definition, 4 points worse than the national rate of 77.6%. The late ones land roughly 45 minutes behind schedule. That rests on 333 flights, with a median arrival 1 minute early.
The national on-time rate over the same period is 77.6%, so AS 744 runs 4 points behind the country as a whole. Across a thousand flights that is about 43 extra late arrivals.

These figures cover 333 flights between July 2025 and June 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.
Schedule
When AS 744 flies
AS 744 flies SEA to PHX without a single fixed slot. Its most common scheduled departure was 15:59, used on 86 of 333 flights, with 15:55 (62 flights) and 15:45 (51 flights) next. Carriers retime flights through the season, so the rates here blend slightly different positions in the aircraft's day.
- Departs 15:5986 flights25.8%
- Departs 15:5562 flights18.6%
- Departs 15:4551 flights15.3%
Scale runs 0% to 100%. Rows with fewer than 30 flights show a dash.
Share of scheduled departures at each local time. Times used on fewer than one flight in ten are not listed.
A 15:59 departure sits in the 2pm–5pm window. Across every US flight scheduled in that window the on-time rate is 72.4%, and AS 744 runs level with that at 73.3%. Midday slots inherit some of the morning's delays without yet carrying the full weight of the evening's.

Across the year
AS 744 quarter by quarter
AS 744 did not run the same all year. Its best quarter was Jan–Mar 2026 at 84.3% on time and its weakest Jul–Sep 2025 at 60.9%, a swing of 23 points on roughly 83 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.
- Jul–Sep 202592 flights60.9%
- Oct–Dec 202589 flights73.0%
- Jan–Mar 202683 flights84.3%
- Apr–Jun 202669 flights76.8%
Scale runs 50% to 90%. Rows with fewer than 30 flights show a dash.
By weekday, AS 744 did best on Saturday at 89.1% on time and worst on Friday at 63.6%. Each day rests on about 48 flights, so a gap of 25 points is worth noticing but could still narrow in another year.
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 4,154 reported delay minutes.
- 41%Carrier
- 33%National Airspace System
- 25%Late-arriving aircraft
The largest share of delay minutes, 41%, falls under carrier control: crew scheduling, maintenance, fuelling, baggage. Unlike weather, that is a management outcome, and it is the category where the gap between two carriers on the same schedule is genuinely earned. It accounts for 1,721 of the 4,154 delay minutes reported here. The split is drawn from 4,154 delay minutes reported on AS 744.
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 routes
What a delay on this flight costs
Badly late arrivals are rare here: only 4.8% land an hour or more behind schedule, against 8.1% nationally. Connections built on this flight are about as safe as US domestic connections get, though a cancelled flight still ignores every layover you give it.
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. 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 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
