Historical statistics for September 2025 to August 2026, not live status. For today’s AS 301, check with Alaska Airlines.
AS 301 sits in the middle of the pack with a C+. About seven flights in ten arrive on time by the DOT's definition, 6 points worse than the national rate of 77.3%. The late ones land about an hour behind schedule. That rests on 341 flights, with a median arrival 5 minutes early.
The national on-time rate over the same period is 77.3%, so AS 301 runs 6 points behind the country as a whole. Across a thousand flights that is about 55 extra late arrivals.

These figures cover 341 flights between September 2025 and August 2026. The median arrival is 5 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.

A 17:13 departure sits in the 5pm–8pm window. Across every US flight scheduled in that window the on-time rate is 68.0%, and AS 301 runs 4 points better at 71.8%. By that time of day most aircraft have flown several legs already, and whatever went wrong earlier is still in the schedule.

Across the year
AS 301 quarter by quarter
AS 301 did not run the same all year. Its best quarter was Jul–Sep 2025 at 80.0% on time and its weakest Jul–Sep 2026 at 62.9%, a swing of 17 points on roughly 68 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.

- Oct–Dec 202589 flights67.4%
- Jan–Mar 202690 flights75.3%
- Apr–Jun 202670 flights77.1%

Scale runs 55% to 85%.
By weekday, AS 301 did best on Wednesday at 83.7% on time and worst on Thursday at 60.4%. Each day rests on about 49 flights, so a gap of 23 points is worth noticing but could still narrow in another year.
Arrival by arrival
How late AS 301 runs when it is late
AS 301 often beats the schedule: 125 of 340 completed flights, 37%, arrived 15 minutes or more early. The 96 late arrivals split 38 under half an hour, 33 between 30 and 60 minutes, and 25 an hour or more.

Share of 340 completed flights by arrival against schedule.
18 of 77 late departures made up the time and arrived on time, 23% of them. In the other direction, 37 flights left on time yet arrived 15 minutes late or more, so that delay built up after pushback: in the air, in a holding pattern or on the ground at PDX.
The worst days
Worst days for AS 301
The latest arrival of the period was on 16 June 2026, 6 hours 27 minutes behind schedule; most of its delay minutes were filed as carrier-caused (crew, maintenance, fuelling, baggage). The five worst days are spread across June, August, July and October, with no single month standing out.
| Date | Arrived late by | Largest filed cause |
|---|---|---|
| 16 June 2026 | 6 hours 27 minutes | Carrier |
| 6 August 2026 | 3 hours 49 minutes | Late-arriving aircraft |
| 13 July 2026 | 3 hours 27 minutes | Late-arriving aircraft |
| 27 October 2025 | 3 hours 5 minutes | Extreme weather |
| 26 August 2026 | 3 hours | Extreme weather |
Delay causes
Why AS 301 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 5,409 reported delay minutes.
- 33%Late-arriving aircraft
- 25%National Airspace System
- 23%Carrier
- 18%Extreme weather
- 0%Security
Extreme weather accounts for 18% 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 3.0 times the usual weather exposure. The split is drawn from 5,409 delay minutes reported on AS 301.
Cancellations are rare at 0.00%, below the national 1.89% and low enough to earn the plus on the grade. Almost no flights are called off; the risk here is arriving late, not not arriving.
Connections and routes
What a delay on this flight costs
7.4% of arrivals land an hour or more late, close to the national 8.3%, so a 60 to 75 minute layover is reasonable here while anything under 45 minutes is a bet. Most delays on this route last about an hour, which a normal layover absorbs.
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.
The same number turns up on one other city pair in the data, including FAI to ANC (15), but none flew often enough under AS 301 to report a rate for. Carriers move flight numbers between routes, so the figures on this page apply to MCO to PDX only.
One caution: this is a thin sample. 341 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
Booking AS 301
For a booking, read AS 301 as 71.8% on time with 0.00% cancelled over 341 flights. Those are rates from the past twelve months, not a forecast for any particular day.
