AS301
Orlando (MCO) to Portland (PDX) · scheduled 7:59 PM – 8:50 PM
How AS301 performs
1,042 operations, July 2023 – July 2026.
AS301 arrived on time 68.7% of the time, against 70.3% for all MCO → PDX flights, so this departure is 1.6 percentage points worse than the route as a whole. Against Alaska Airlines’ own flights on this route it is 1.6 points worse.

Why AS301 runs late
Where US DOT attributed the delay minutes on this flight.
the inbound aircraft was late, so this flight started late
airspace and airport capacity, including weather-driven flow control
crew, maintenance, boarding and fueling, all within the carrier’s control
weather severe enough to stop this flight specifically
screening or terminal security incidents
Share of the delay minutes US DOT attributed to each cause for AS301 on MCO → PDX. Only delays of 15 minutes or more are attributed.

Does a late aircraft delay this flight?
How often the plane that flies AS301 comes in late, and what that does to the departure.
When the aircraft came in 15 or more minutes late, AS301 pushed back an average of 57 minutes late; when it came in on time or early, an average of 2 minutes late.
Each departure is matched to the flight the same aircraft flew into MCO just before it, using the tail number in the DOT file, 1,014 of 1,029 departures in all. A departure is left out when that flight is unknown, was cancelled or diverted, or the aircraft had sat for more than 12 hours. A flight the airline cancelled never left and is not in the count, and one flown by a substitute aircraft is matched to the aircraft that flew it, not to the one first planned.
Against the network at the same turn length
| Share of departures | Inbound landed 15+ late | Left 15+ late after a late inbound | Left 15+ late after an on-time inbound |
|---|---|---|---|
| AS301 | 25% | 85% | 10% |
| Network, same turn | 17% | 68% | 9% |
The schedule leaves a normal turn: enough time to clean and board if the aircraft is on time, little to spare if it is not.
The network row is every flight with a scheduled turn of 60 to 89 minutes. How often AS301’s aircraft landed 15 or more minutes late is higher than the network’s and, once the aircraft was late, how often AS301 left 15 or more minutes late is higher than the network’s.

From pushback to gate
When it leaves MCO late, does that still matter by the time it reaches PDX?
AS301 pushes back an average of 17.6 minutes late and reaches the gate at PDX an average of 13.4 minutes late. The 4.3 minutes between those two figures are slack the published schedule already carries, which is why a late pushback on this flight does not reliably become a late arrival. It spends 23.8 minutes on the taxiways at MCO, 4.4 minutes longer than a typical MCO departure in the same hour.
On arrival at PDX, AS301 spends 5.5 min taxiing from touchdown to the gate — ground time a connecting passenger sits through before they can even leave the aircraft, on top of however late the flight itself ran. That is about what any arrival at PDX spends on the ground before reaching the gate.
Departure delay is averaged over every pushback and arrival delay over every completed arrival, so the two counts differ by the flights that never reached PDX. Taxi-out is gate to wheels up and sits inside the scheduled block rather than on top of it; the comparison is 34,680 departures from MCO scheduled in the clock hour AS301 most often leaves in. Taxi-in is landing to gate, compared against every arrival FlyerIntel has on file at PDX (187,629 flights), not just AS301’s own. More on taxi time.

The hour it leaves MCO
Part of any flight’s record belongs to the clock rather than to the flight. AS301 has one departure time, so this is what that time is worth.
On-time arrival rate. 34,680 departures from MCO are scheduled in the 7 PM–8 PM hour over the period, against 498,221 across the whole day.
AS301 is scheduled out of MCO at 7:59 PM, in the 7 PM–8 PM bank. Departures from MCO in that hour arrive on time 61.7% of the time against 74.8% across the airport’s whole day — the slot alone is worth 13.0 points worse before anything about this particular flight is considered.
The two airport figures cover every departure from MCO to every destination, so they describe the slot rather than this journey — the like-for-like comparison against the route is above. Hours are scheduled local, and a number whose schedule moved between banks inside the period has no single hour and is not described here at all. Why the hour matters.

By day of week
Does AS301 run worse on particular days?
Tuesday is historically the most reliable day and Thursday the least, a gap of 9.9 percentage points.

Other routes AS301 has flown
A flight number is a slot in a schedule, and carriers reassign it. These are the other city pairs this number served in the analysis period.
| Route | Operated | Flights | On time |
|---|---|---|---|
| FAI→ANC Fairbanks to Anchorage | April 22, 2026 – May 12, 2026 | 15 | — |
Because the same number has served different journeys, the statistics above describe only the route AS301 currently operates. Blending them would produce an average of two different flights.
When it goes wrong
The average describes a usual day. This is the day that ruins a connection.
69 min late
against a median of 1 min early
AS301 has an average that understates its risk: a typical arrival is 1 min early, but the worst tenth are 70 minutes worse than that. If the trip has something unmissable at the end of it, the median is the wrong number to plan against.

Data and methodology
Calculated by FlyerIntel from 1,042 records of AS301 operating MCO → PDX, published by the US DOT Bureau of Transportation Statistics. A flight counts as delayed when it arrives 15 or more minutes after schedule. Cancelled and diverted flights are excluded from the on-time rate and reported separately. Flight numbers are resolved as carrier plus number plus route, because the same number serves different routes over time.
