These figures cover 728 flights between September 2025 and August 2026. The median arrival is 12 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.

Across the year
When delays peak on this route
This route's year swings by 21 points from best month to worst, which is wide. An annual average tells you very little about the week you are actually flying, so read the strip rather than the headline if your dates are fixed.
February is the weak month at 78.6% on time, against 100.0% in April. Winter delays cluster: a single storm system can account for most of a month's shortfall, so an average December hides both very good weeks and genuinely unflyable days. January was the busiest month here, with 62 flights.
Across the week, Wednesday is the strongest day at 94.2% on time and Saturday the weakest at 80.4%, a spread of 14 points.
Delay causes
Why this route gets delayed
Carrier accounts for 47% of the 3,263 delay minutes carriers reported here, and the remaining four split what is left.
- 47%Carrier
- 35%National Airspace System
- 10%Extreme weather
- 9%Late-arriving aircraft
35% 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 1,129 minutes out of 3,263, against a national NAS share of 21%. The split is drawn from 3,263 reported delay minutes.
The largest share of delay minutes, 47%, falls under carrier control: crew scheduling, maintenance, fuelling, baggage. It accounts for 1,530 of the 3,263 delay minutes reported here.
Cancellations are rare at 0.41%, below the national 1.89% 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 stage length
What a delay here actually costs
Badly late arrivals are rare here: only 1.9% land an hour or more behind schedule, against 8.3% 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 2,561 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 return leg is a different operation and performs like one: it runs 85.2% on time across 728 flights, 4 points below this direction. Departure banks, aircraft rotations and the congestion at each end all differ, so scoring the two directions together would average away a real 4 points of difference.
One caution: this is a thin sample. 728 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 this route
Put together: treat all of this as provisional. 728 flights over twelve months is enough to clear this site's floor and not enough to be confident to better than a couple of points. The 89.4% headline is the most reliable number on the page; the hour and month splits below it are built on a few dozen flights each. 724 completed flights over 12 months sit behind that.
Common questions
PDX to OGG questions
How often is PDX to OGG delayed?
About one flight in nine arrives at least 15 minutes late, which is the Department of Transportation's definition of a delayed arrival. That works out to 10.6% of the 728 flights in this analysis, against 22.7% nationally. Delayed flights are late by roughly 40 minutes on average.
How reliable is PDX to OGG compared with the rest of the country?
89.4% of flights arrive on time here against a national 77.3%, a difference of 12 points in its favour. That is worth a A+ on this site's grading scale.
What time of day has the fewest delays on PDX to OGG?
The 5am–8am departure window is the strongest at 90.7% on time. The 5pm–8pm window is the weakest at 87.9%, 3 points behind. Later departures inherit delays from earlier flights the same aircraft has already flown, which is why the curve slopes the way it does.
How bad are February delays on PDX to OGG?
February is the weakest month at 78.6% on time, compared with 100.0% in April. Across the year that is 21 points between the best and worst months. Moving flexible dates out of that month is one of the few things that reliably helps.
