These figures cover 337 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 412 flies

AS 412 flies SEA to PIT without a single fixed slot. Its most common scheduled departure was 11:06, used on 81 of 337 flights, with 10:53 (35 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 11:06 departure sits in the 11am–2pm window. Across every US flight scheduled in that window the on-time rate is 78.8%, and AS 412 runs 3 points worse at 75.4%. Midday slots inherit some of the morning's delays without yet carrying the full weight of the evening's.

Across the year

AS 412 quarter by quarter

AS 412 did not run the same all year. Its best quarter was Oct–Dec 2025 at 80.7% on time and its weakest Jul–Sep 2025 at 63.0%, a swing of 18 points on roughly 84 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 412 did best on Tuesday at 83.7% on time and worst on Monday at 66.0%. Each day rests on about 48 flights, so a gap of 18 points is worth noticing but could still narrow in another year.

Delay causes

Why AS 412 runs late

One category carries most of the weight here. Carrier accounts for 51% of the 4,256 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.

Late-arriving aircraft
33%
National Airspace System
13%
Extreme weather
3%

The largest share of delay minutes, 51%, 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 2,153 of the 4,256 delay minutes reported here. The split is drawn from 4,256 delay minutes reported on AS 412.

Cancellations are rare at 0.89%, 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

7.2% of arrivals land an hour or more late, close to the national 8.1%. That is the figure that decides a connection, and it says a 60 to 75 minute layover is reasonable here while anything under 45 minutes is a bet. Most delays on this route last roughly 50 minutes, which a normal layover absorbs.

At 2,125 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 412 is not only a SEA to PIT flight. It also flew PIT to SEA (310 flights, 66.1% 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. 337 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.
