Historical statistics for July 2025 to June 2026, not live status. For today’s AS 414, check with Alaska Airlines.

AS 414 earns an A. Close to nine flights in ten arrive inside the 15-minute window the DOT uses to define an on-time arrival, which puts it 11 points better than the national rate of 77.6%. When something does go wrong the average delay runs roughly 50 minutes. That rests on 323 flights, with a median arrival 12 minutes early.

Set against the rest of the country, AS 414's record is 11 points better than the US average of 77.6%. That gap is worth roughly 107 fewer late arrivals for every thousand flights.

These figures cover 323 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 414 flies

AS 414 flies SEA to DFW without a single fixed slot. Its most common scheduled departure was 08:30, used on 64 of 323 flights, with 08:17 (50 flights) and 08:23 (36 flights) next. Carriers retime flights through the season, so the rates here blend slightly different positions in the aircraft's day.

Share of scheduled departures at each local time. Times used on fewer than one flight in ten are not listed.

A 08:30 departure sits in the 8am–11am window. Across every US flight scheduled in that window the on-time rate is 84.1%, and AS 414 runs 4 points better at 88.3%. Early departures usually start with an aircraft that has not flown yet that day, which is most of why the window does well.

Across the year

AS 414 quarter by quarter

AS 414 did not run the same all year. Its best quarter was Oct–Dec 2025 at 92.5% on time and its weakest Jul–Sep 2025 at 81.8%, a swing of 11 points on roughly 81 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 202590 flights81.8%
Oct–Dec 202581 flights92.5%
Jan–Mar 202689 flights89.5%
Apr–Jun 202663 flights90.5%

Scale runs 75% to 100%. Rows with fewer than 30 flights show a dash.

By weekday, AS 414 did best on Wednesday at 100.0% on time and worst on Friday at 82.2%. Each day rests on about 46 flights, so a gap of 18 points is worth noticing but could still narrow in another year.

Delay causes

Why AS 414 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 1,780 reported delay minutes.

National Airspace System
37%
Carrier
29%
Late-arriving aircraft
18%
Extreme weather
16%

Extreme weather accounts for 16% of delay minutes, well above the single-digit share typical across the system. Weather delays are lumpy: they arrive as whole bad days rather than as a steady drag, so the quarterly figures above are the more useful view of the risk. The national share is 6%, so this operation carries roughly 2.6 times the usual weather exposure. The split is drawn from 1,780 delay minutes reported on AS 414.

Cancellations sit at 1.55% against a national 1.81%, which is ordinary. Diversions add another 0.31%.

Connections and routes

What a delay on this flight costs

Badly late arrivals are rare here: only 2.5% 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 1,660 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.

Every one of the 323 flights under AS 414 in the data flew SEA to DFW. 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. 323 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.
