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 16 points better than the national rate of 77.3%. When something does go wrong the average delay runs close to two hours. That rests on 860 OGG to PHX flights, of which Southwest Airlines flew 365 at 96.7% on time.
Set against the rest of the country, this route's record is 16 points better than the US average of 77.3%. That gap is worth roughly 157 fewer late arrivals for every thousand flights.

These figures cover 860 flights between September 2025 and August 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 choice of carrier is not cosmetic here. Southwest Airlines arrives on time 96.7% of the time; American Airlines manages 90.2%. Sample sizes sit next to every figure, because a two-point gap across 495 flights means less than a ten-point one.
| Airline | Flights | On time | Avg delay | Cancelled | Grade |
|---|---|---|---|---|---|
| Southwest Airlines | 365 | 96.7% | 35 min | 0.27% | A+ |
| American Airlines | 495 | 90.2% | 141 min | 0.61% | A+ |
Southwest leads American by 7 points. Real, but small enough that a better departure time on the weaker carrier can outweigh it.

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 | 96.4% | 96.7% | 0.27% | 8pm–5am, Mon | — |
| 2. OGG → PHXKahului to Phoenix | American Airlines | 89.6% | 90.2% | 0.61% | 8pm–5am, Wed | AA 432 22:00 |
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 860 flights.

The overnight block holds up unusually well at 93.0% on time across 860 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 860 flights scheduled in it.

Across the year
When delays peak on this route
This route's year swings by 17 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.
July is the worst month at 82.8% on time, 17 points below February, the best at 100.0%. Summer afternoon convection and peak-season schedules land on the same weeks every year, so this is a pattern you can book around rather than a run of bad luck. March was the busiest month here, with 93 flights.
Across the week, Wednesday is the strongest day at 96.7% on time and Sunday the weakest at 90.2%, a spread of 7 points.
Delay causes
Why this route gets delayed
Late-arriving aircraft accounts for 50% of the 7,207 delay minutes carriers reported here, and the remaining four split what is left.
- 50%Late-arriving aircraft
- 37%Carrier
- 11%National Airspace System
- 1%Extreme weather
50% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. Across 7,207 reported delay minutes here, that single category outweighs weather by 36 to one. The split is drawn from 7,207 reported delay minutes.
The largest share of delay minutes, 37%, falls under carrier control: crew scheduling, maintenance, fuelling, baggage. It accounts for 2,673 of the 7,207 delay minutes reported here.
Cancellations are rare at 0.47%, 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 1.6% 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 2,844 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 83.2% on time across 860 flights, 10 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 10 points of difference.
One caution: this is a thin sample. 860 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. 860 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 93.0% headline is the most reliable number on the page; the hour and month splits below it are built on a few dozen flights each. 856 completed flights over 12 months sit behind that.
Common questions
OGG to PHX questions
How often is OGG to PHX delayed?
About one flight in fifteen arrives at least 15 minutes late, which is the Department of Transportation's definition of a delayed arrival. That works out to 7.0% of the 860 flights in this analysis, against 22.7% nationally. Delayed flights are late by close to two hours on average.
Which airline is most reliable on OGG to PHX?
Southwest Airlines leads at 96.7% on time across 365 flights. American Airlines is at the other end on 90.2%, a gap of 7 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 93.0% is the figure to plan against.
How bad are July delays on OGG to PHX?
July is the weakest month at 82.8% on time, compared with 100.0% in February. Across the year that is 17 points between the best and worst months. Moving flexible dates out of that month is one of the few things that reliably helps.
