Historical statistics for July 2025 to June 2026, not live status. For today’s AS 700, check with Alaska Airlines.
AS 700 lands a B+, 2 points better than the national rate of 77.6%. About one flight in five arrives 15 minutes late or worse, and those flights are late by roughly 45 minutes on average. That is a workable record, not a spotless one. That rests on 358 flights, with a median arrival 4 minutes early.

These figures cover 358 flights between July 2025 and June 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.
Schedule
When AS 700 flies
AS 700 flies SEA to PHX without a single fixed slot. Its most common scheduled departure was 14:02, used on 71 of 358 flights, with 13:58 (54 flights) and 13:35 (50 flights) next. Carriers retime flights through the season, so the rates here blend slightly different positions in the aircraft's day.

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 14:02 departure sits in the 2pm–5pm window. Across every US flight scheduled in that window the on-time rate is 72.4%, and AS 700 runs 7 points better at 79.6%. Midday slots inherit some of the morning's delays without yet carrying the full weight of the evening's.
Against the route
AS 700 next to SEA to PHX
Every carrier on SEA to PHX combined arrived on time 79.2% of the time across 7,268 flights, so AS 700 is about level with it. Alaska flew 2,906 flights on the same city pair under all its flight numbers, including this one, and those ran 79.0% on time. Across its whole network Alaska Airlines managed 79.1%, close to this flight's figure.

Across the year
AS 700 quarter by quarter
AS 700 did not run the same all year. Its best quarter was Jan–Mar 2026 at 89.9% on time and its weakest Oct–Dec 2025 at 71.1%, a swing of 19 points on roughly 90 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 202590 flights71.1%
- Jan–Mar 202689 flights89.9%
- Apr–Jun 202687 flights86.2%
Scale runs 65% to 95%. Rows with fewer than 30 flights show a dash.
By weekday, AS 700 did best on Friday at 88.2% on time and worst on Thursday at 71.2%. Each day rests on about 51 flights, so a gap of 17 points is worth noticing but could still narrow in another year.
Delay causes
Why AS 700 runs late
One category carries most of the weight here. Carrier accounts for 42% of the 3,447 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.
- 42%Carrier
- 36%Late-arriving aircraft
- 20%National Airspace System
- 2%Extreme weather
36% 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 3,447 reported delay minutes here, that single category outweighs weather by 24 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 3,447 delay minutes reported on AS 700.
Cancellations are rare at 0.28%, below the national 1.81% 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
Badly late arrivals are rare here: only 3.9% 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.
Every one of the 358 flights under AS 700 in the data flew SEA to PHX. The number was not reused on any other city pair, which makes this a clean record of one route.
One caution: this is a thin sample. 358 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 700
For a booking, read AS 700 as 79.6% on time with 0.28% cancelled over 358 flights. Those are rates from the past twelve months, not a forecast for any particular day.
