Historical statistics for July 2025 to June 2026, not live status. For today’s AS 326, check with Alaska Airlines.
AS 326 lands a B+, 5 points better than the national rate of 77.6%. About one flight in six arrives 15 minutes late or worse, and those flights are late by roughly 50 minutes on average. That is a workable record, not a spotless one. That rests on 344 flights, with a median arrival 12 minutes early.
Set against the rest of the country, AS 326's record is 5 points better than the US average of 77.6%. That gap is worth roughly 54 fewer late arrivals for every thousand flights.

These figures cover 344 flights between July 2025 and June 2026. The median arrival is 12 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 326 flies
AS 326 flies SEA to TPA without a single fixed slot. Its most common scheduled departure was 09:11, used on 75 of 344 flights, with 09:24 (50 flights) and 09:30 (45 flights) next. Carriers retime flights through the season, so the rates here blend slightly different positions in the aircraft's day.
- Departs 09:1175 flights21.8%
- Departs 09:2450 flights14.5%
- Departs 09:3045 flights13.1%
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 09:11 departure sits in the 8am–11am window. Across every US flight scheduled in that window the on-time rate is 84.1%, and AS 326 runs level with that at 83.0%. Early departures usually start with an aircraft that has not flown yet that day, which is most of why the window does well.
Against the route

Across its whole network Alaska Airlines managed 79.1%, which this flight beats by 4 points.

Across the year
AS 326 quarter by quarter
AS 326 did not run the same all year. Its best quarter was Apr–Jun 2026 at 91.3% on time and its weakest Jul–Sep 2025 at 76.4%, a swing of 15 points on roughly 86 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 326 did best on Wednesday at 89.6% on time and worst on Tuesday at 74.0%. Each day rests on about 49 flights, so a gap of 16 points is worth noticing but could still narrow in another year.
Delay causes
Why AS 326 runs late
One category carries most of the weight here. Carrier accounts for 52% of the 2,924 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.
- 52%Carrier
- 25%National Airspace System
- 22%Late-arriving aircraft
- 1%Extreme weather
The largest share of delay minutes, 52%, 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 1,533 of the 2,924 delay minutes reported here. The split is drawn from 2,924 delay minutes reported on AS 326.
Cancellations are rare at 0.87%, 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 3.6% 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.
At 2,520 miles this is transcontinental flying, and long routes get a quiet structural advantage. Scheduled block time on a flight this length carries more padding in absolute minutes, so a twenty-minute late departure often still becomes an on-time arrival. Read the on-time rate here as slightly flattering next to a short-haul route with the same operational quality.
AS 326 is not only a SEA to TPA flight. It also flew TPA to SEA (275 flights, 58.0% on time) often enough to be scored on its own. Airlines attach one number to several legs of an aircraft's day, and each leg keeps its own record here, so check which city pair is on your booking before reading a rate.
One caution: this is a thin sample. 344 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.
