This route 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 77.3%. When something does go wrong the average delay runs about an hour. That rests on 828 XNA to PHX flights, with a median arrival 10 minutes early.
Best time to fly XNA to PHX: a 8am–11am departure, ideally on a Wednesday. Flights in that window arrived on time 91.7% of the time and Wednesday flights 95.7%, against 88.2% for the route overall.
Set against the rest of the country, this route's record is 11 points better than the US average of 77.3%. That gap is worth roughly 109 fewer late arrivals for every thousand flights.

These figures cover 828 flights between September 2025 and August 2026. The median arrival is 10 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.

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 828 flights.

Scale runs 75% to 95%. Rows with fewer than 30 flights show a dash.
The early departures do better, though not dramatically: 91.7% on time for the 8am–11am window against 85.6% for 2pm–5pm. Worth taking if the schedule allows, not worth an extra connection. The 8am–11am window is the busiest, with 364 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.
June is the worst month at 78.3% on time, 17 points below August, the best at 95.2%. 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 91 flights.
Across the week, Wednesday is the strongest day at 95.7% on time and Sunday the weakest at 83.9%, a spread of 12 points.
Delay causes
Why this route gets delayed
Late-arriving aircraft accounts for 54% of the 6,014 delay minutes carriers reported here, and the remaining four split what is left.
- 54%Late-arriving aircraft
- 19%Carrier
- 14%Extreme weather
- 13%National Airspace System
Extreme weather accounts for 14% 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 2.3 times the usual weather exposure. The split is drawn from 6,014 reported delay minutes.
54% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. Across 6,014 reported delay minutes here, that single category outweighs weather by 4 to one.
Cancellations are rare at 0.36%, 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 3.0% 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.
The 1,023 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.
The return leg is a different operation and performs like one: it runs 84.0% on time across 827 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. 828 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. 828 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 88.2% headline is the most reliable number on the page; the hour and month splits below it are built on a few dozen flights each. 825 completed flights over 12 months sit behind that.
Common questions
XNA to PHX questions
How often is XNA to PHX delayed?
About one flight in eight arrives at least 15 minutes late, which is the Department of Transportation's definition of a delayed arrival. That works out to 11.8% of the 828 flights in this analysis, against 22.7% nationally. Delayed flights are late by about an hour on average.
How reliable is XNA to PHX compared with the rest of the country?
88.2% of flights arrive on time here against a national 77.3%, a difference of 11 points in its favour. That is worth a A+ on this site's grading scale.
What time of day has the fewest delays on XNA to PHX?
The 8am–11am departure window is the strongest at 91.7% on time. The 2pm–5pm window is the weakest at 85.6%, 6 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 June delays on XNA to PHX?
June is the weakest month at 78.3% on time, compared with 95.2% in August. 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.
