Historical statistics for July 2025 to June 2026, not live status. For today’s AS 122, check with Alaska Airlines.
AS 122 earns an A+. Close to nine flights in ten arrive inside the 15-minute window the DOT uses to define an on-time arrival, which puts it 11 points better than the national rate of 77.6%. When something does go wrong the average delay runs about an hour. That rests on 283 flights, with a median arrival 9 minutes early.
Set against the rest of the country, AS 122's record is 11 points better than the US average of 77.6%. That gap is worth roughly 110 fewer late arrivals for every thousand flights.

These figures cover 283 flights between July 2025 and June 2026. The median arrival is 9 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 122 flies
AS 122 flies BUR to PDX without a single fixed slot. Its most common scheduled departure was 14:21, used on 52 of 283 flights, with 14:07 (50 flights) and 14:10 (39 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 14:21 departure sits in the 2pm–5pm window. Across every US flight scheduled in that window the on-time rate is 72.4%, and AS 122 runs 16 points better at 88.6%. Midday slots inherit some of the morning's delays without yet carrying the full weight of the evening's.

Across the year
AS 122 quarter by quarter
AS 122 did not run the same all year. Its best quarter was Jan–Mar 2026 at 92.1% on time and its weakest Jul–Sep 2025 at 81.2%, a swing of 11 points on roughly 94 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 122 did best on Monday at 100.0% on time and worst on Thursday at 80.0%. Each day rests on about 40 flights, so a gap of 20 points is worth noticing but could still narrow in another year.
Delay causes
Why AS 122 runs late
One category carries most of the weight here. Late-arriving aircraft accounts for 48% of the 2,112 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.
- 48%Late-arriving aircraft
- 34%Carrier
- 10%National Airspace System
- 8%Extreme weather
48% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. That is a cascade, and cascades start small and grow through the day. Across 2,112 reported delay minutes here, that single category outweighs weather by 6 to one. It is the strongest argument for booking the first departure of the morning, when the aircraft has been sitting at the gate overnight with nothing to inherit. The split is drawn from 2,112 delay minutes reported on AS 122.
Cancellations are rare at 0.71%, 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 4.6% 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.
The 817 miles between these two airports put this in the middle of the US network, around two and a half to three hours of block time. That is enough cruise to absorb a ten-minute late pushback and not enough to absorb thirty. It is also long enough that the aircraft usually flies three or four legs a day rather than six, which slows how fast delay compounds.
The same number turns up on one other city pair in the data, including HNL to SEA (39), but none flew often enough under AS 122 to report a rate for. Carriers move flight numbers between routes, so the figures on this page apply to BUR to PDX only.
One caution: this is a thin sample. 283 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 122
For a booking, AS 122 has one of the better records a US domestic flight can show: 88.6% on time and 0.71% cancelled. That is a base rate, not a promise about any single day.
