Historical statistics for July 2025 to June 2026, not live status. For today’s AS 300, check with Alaska Airlines.

AS 300 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 364 flights, with a median arrival 7 minutes early.

These figures cover 364 flights between July 2025 and June 2026. The median arrival is 7 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 300 flies

AS 300 flies PDX to MCO without a single fixed slot. Its most common scheduled departure was 07:05, used on 64 of 364 flights, with 10:35 (50 flights) and 07:00 (47 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 07:05 departure sits in the 5am–8am window. Across every US flight scheduled in that window the on-time rate is 89.3%, and AS 300 runs 9 points worse at 79.9%. 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 300 next to PDX to MCO

Every carrier on PDX to MCO combined arrived on time 79.2% of the time across 391 flights, so AS 300 is about level with it. Across its whole network Alaska Airlines managed 79.1%, close to this flight's figure.

Across the year

AS 300 quarter by quarter

AS 300 did not run the same all year. Its best quarter was Apr–Jun 2026 at 89.9% on time and its weakest Jul–Sep 2025 at 60.2%, a swing of 30 points on roughly 91 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 202592 flights60.2%
Oct–Dec 202591 flights83.5%
Jan–Mar 202690 flights85.6%
Apr–Jun 202691 flights89.9%

Scale runs 50% to 95%. Rows with fewer than 30 flights show a dash.

By weekday, AS 300 ranged from 76.0% on Thursday to 82.4% on Monday. With about 52 flights behind each day, a spread of 6 points is inside normal variation, so the day you fly is not worth changing for this flight.

Delay causes

Why AS 300 runs late

One category carries most of the weight here. National Airspace System accounts for 50% of the 3,410 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.

The largest share of delay minutes, 34%, 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 1,173 of the 3,410 delay minutes reported here. The split is drawn from 3,410 delay minutes reported on AS 300.

Cancellations are rare at 0.55%, 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 4.2% 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 2,535 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 364 flights under AS 300 in the data flew PDX to MCO. 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. 364 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
