These figures cover 293 flights between July 2025 and June 2026. The median arrival is 2 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 299 flies

AS 299 flies EWR to SEA without a single fixed slot. Its most common scheduled departure was 07:19, used on 117 of 293 flights, with 07:30 (55 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 07:19 departure sits in the 5am–8am window. Across every US flight scheduled in that window the on-time rate is 89.3%, and AS 299 runs 15 points worse at 74.0%. 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

AS 299 next to EWR to SEA

Every carrier on EWR to SEA combined arrived on time 73.5% of the time across 2,234 flights, so AS 299 is about level with it. Alaska flew 1,237 flights on the same city pair under all its flight numbers, including this one, and those ran 70.6% on time. Across its whole network Alaska Airlines managed 79.1%, which this flight trails by 5 points.

Across the year

AS 299 quarter by quarter

AS 299 did not run the same all year. Its best quarter was Apr–Jun 2026 at 89.0% on time and its weakest Oct–Dec 2025 at 57.8%, a swing of 31 points on roughly 98 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 299 did best on Wednesday at 85.4% on time and worst on Monday at 65.9%. Each day rests on about 42 flights, so a gap of 20 points is worth noticing but could still narrow in another year.

Delay causes

Why AS 299 runs late

One category carries most of the weight here. National Airspace System accounts for 61% of the 4,013 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.

61%
Carrier
23%
Late-arriving aircraft
14%
Extreme weather
2%

61% of delay minutes are charged to the National Airspace System: air traffic volume, runway configuration, ground stops. No carrier can price its way out of that, which is why airport choice moves the number here more than carrier choice does. That is 2,466 minutes out of 4,013, against a national NAS share of 21%. The split is drawn from 4,013 delay minutes reported on AS 299.

Cancellations sit at 1.37% against a national 1.81%, which is ordinary. Diversions add another 0.00%.

Connections and routes

What a delay on this flight costs

5.9% 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 55 minutes, which a normal layover absorbs.

At 2,402 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.

The same number turns up on one other city pair in the data, including BOS to SEA (34), but none flew often enough under AS 299 to report a rate for. Carriers move flight numbers between routes, so the figures on this page apply to EWR to SEA only.

One caution: this is a thin sample. 293 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.
