This route earns an A+. Nearly every flight arrives inside the 15-minute window the DOT uses to define an on-time arrival, which puts it 17 points better than the national rate of 77.6%. When something does go wrong the average delay runs about 2.4 hours. That rests on 825 OGG to PHX flights, of which Southwest Airlines flew 365 at 97.3% on time.
Set against the rest of the country, this route's record is 17 points better than the US average of 77.6%. That gap is worth roughly 167 fewer late arrivals for every thousand flights.

These figures cover 825 flights between July 2025 and June 2026. The median arrival is 15 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.
Carrier by carrier
Which airline is most reliable on OGG to PHX
The two carriers here are closely matched: 5 points separate the best from the worst. At that spread, schedule and price are better tie-breakers than reliability. Sample sizes are shown so you can see which rows are worth weighing.
| Airline | Flights | On time | Avg delay | Cancelled | Grade |
|---|---|---|---|---|---|
| Southwest Airlines | 365 | 97.3% | 42 min | 0.27% | A+ |
| American Airlines | 460 | 91.9% | 169 min | 0.43% | A+ |
No carrier stands out. Southwest tops the table at 97.3%, 5 points clear of the bottom, which is inside the range this kind of sample moves year to year.

Best ways to make this trip
The most reliable ways to fly Kahului to Phoenix
Every airline on this route, ranked by how often a scheduled flight actually operated and arrived on time, with its best departure time and most punctual flight number. No nearby airport pair beat these.
| Option | Airline | Success | On time | Cancelled | Best departure | Most punctual flight |
|---|---|---|---|---|---|---|
| 1. OGG → PHXKahului to Phoenix | Southwest Airlines | 97.0% | 97.3% | 0.27% | 8pm–5am, Mon | — |
| 2. OGG → PHXKahului to Phoenix | American Airlines | 91.5% | 91.9% | 0.43% | 8pm–5am, Mon | AA 432 21:48 |
Success is the share of scheduled flights that operated and arrived less than 15 minutes late, so a cancelled flight counts against it. “(route)” means the best time comes from every carrier on the route rather than this airline alone.
Departure window
The best time of day to leave
Departure time is the single lever a traveller controls, and it moves the odds more than most people expect. Each bar below is the on-time rate for flights scheduled to leave inside that window, across 825 flights.
- 5am–8am—
- 8am–11am—
- 11am–2pm—
- 2pm–5pm—
- 5pm–8pm—
- 8pm–5am825 flights94.3%
Scale runs 85% to 100%. Rows with fewer than 30 flights show a dash.
The overnight block holds up unusually well at 94.3% on time across 825 flights. Red-eyes fly into empty airspace and empty gates, and they are the first rotation of the aircraft's day rather than the last. The 8pm–5am window is the busiest, with 825 flights scheduled in it.
Across the year
When delays peak on this route
This route's year swings by 15 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.
Delays peak in March, when the on-time rate falls to 84.6%. February is the strongest month at 100.0%. Moving a flexible trip across that boundary buys 15 points. March was the busiest month here, with 93 flights.
Across the week, Monday is the strongest day at 96.6% on time and Sunday the weakest at 92.4%. 4 points is a smaller lever than departure hour, but it is free.
Delay causes
Why this route gets delayed
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 6,686 reported delay minutes.
- 42%Late-arriving aircraft
- 35%Carrier
- 16%Extreme weather
- 8%National Airspace System
Extreme weather accounts for 16% 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 monthly strip above is the more useful view of the risk. The national share is 6%, so this operation carries roughly 2.5 times the usual weather exposure. The split is drawn from 6,686 reported delay minutes.
42% 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 6,686 reported delay minutes here, that single category outweighs weather by 3 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.
Cancellations are rare at 0.36%, 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 stage length
What a delay here actually costs
Badly late arrivals are rare here: only 1.7% 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 2,844 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 83.8% on time across 825 flights, 11 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 11 points of difference.
One caution: this is a thin sample. 825 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. 825 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 94.3% headline is the most reliable number on the page; the hour and month splits below it are built on a few dozen flights each. 822 completed flights over 12 months sit behind that.
Common questions
OGG to PHX questions
How often is OGG to PHX delayed?
Roughly one flight in twenty arrives at least 15 minutes late, which is the Department of Transportation's definition of a delayed arrival. That works out to 5.7% of the 825 flights in this analysis, against 22.4% nationally. Delayed flights are late by about 2.4 hours on average.
Which airline is most reliable on OGG to PHX?
Southwest Airlines leads at 97.3% on time across 365 flights. American Airlines is at the other end on 91.9%, a gap of 5 points. Sample size matters as much as the percentage: a rate built from a few hundred flights moves around far more than one built from ten thousand.
Does the departure time change the odds on OGG to PHX?
Not by much in this data. Every departure window falls within half a point of the others, so there is no hour worth rearranging a trip for. The overall rate of 94.3% is the figure to plan against.
How bad are March delays on OGG to PHX?
March is the weakest month at 84.6% on time, compared with 100.0% in February. Across the year that is 15 points between the best and worst months. Moving flexible dates out of that month is one of the few things that reliably helps.
