Historical statistics for July 2025 to June 2026, not live status. For today’s flights, check with American Airlines.
American on PHX to LAS lands a B+, 2 points better than the national rate of 77.6%. About one flight in five arrives 15 minutes late or worse, and those flights are late by about an hour on average. That is a workable record, not a spotless one. That rests on 1,687 flights. The strongest carrier on the route with a full sample, Frontier Airlines, flew 861 at 82.7% on time.
The US average over the same twelve months is 77.6%, so there is little to separate American on PHX to LAS from the country as a whole. The variation that matters here is internal: which carrier, and what time of day.

These figures cover 1,687 flights between July 2025 and June 2026. Beyond the headline rate, 8.0% of arrivals land a full hour or more behind schedule. That is the number that wrecks a connection, and it is not visible in an on-time percentage alone.
Carrier by carrier
American against every carrier on PHX to LAS
American flew 1,687 of the 6,021 flights on PHX to LAS, about 28% of it. Its 79.1% on time is about level with the route as a whole at 78.7%. Ranked by on-time rate it is number five of six carriers on the route, where the range runs from Spirit at 100.0% to Southwest at 77.3%. Three of those carriers flew fewer than 365 flights here, so treat their positions as rough.
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.

No carrier stands out. Frontier tops the table at 82.7%, 5 points clear of the bottom, which is inside the range this kind of sample moves year to year.

Departure window
When American runs best on this route
Departure time matters more here than the choice of carrier. The gap between the best and worst window is 26 points, against 5 points between the best and worst carrier. Each bar is the on-time rate for flights scheduled inside that window.
- 5am–8am123 flights94.3%
- 8am–11am399 flights86.4%
- 11am–2pm427 flights80.4%
- 2pm–5pm188 flights73.9%
- 5pm–8pm307 flights68.0%
- 8pm–5am243 flights75.2%
Scale runs 60% to 100%. Rows with fewer than 30 flights show a dash.
Book the early departure. Flights leaving between 5am–8am arrive on time 94.3% of the time, against 68.0% for the evening window. That is 26 points of difference for no extra money, and it comes from the same aircraft having had no earlier flight to fall behind on. The 11am–2pm window is the busiest, with 427 flights scheduled in it.
Across the year
American on PHX to LAS through the year
June is the worst month at 74.5% on time, 14 points below August, the best at 88.8%. 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. October was the busiest month here, with 158 flights.
Across the week, Wednesday is the strongest day at 87.8% on time and Sunday the weakest at 70.4%. 17 points is a smaller lever than departure hour, but it is free.
Delay causes
Why American runs late on this route
One category carries most of the weight here. Late-arriving aircraft accounts for 54% of the 23,000 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.
- 54%Late-arriving aircraft
- 24%Carrier
- 18%National Airspace System
- 4%Extreme weather
- 0%Security
54% 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 23,000 reported delay minutes here, that single category outweighs weather by 15 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 23,300 reported delay minutes.
The practical consequence: the 5am–8am departure is the one that starts clean. Its aircraft has no earlier leg to be late from, which is exactly why that window shows 94.3% on time here.
Cancellations are rare at 0.83%, 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 costs
8.0% of arrivals land an hour or more late, close to the national 8.1%. That is the figure that decides a connection, and it says a 60 to 75 minute layover is reasonable here while anything under 45 minutes is a bet. Most delays on this route last about an hour, which a normal layover absorbs.
At 255 miles this is a short hop, and stage length matters more than it looks. A flight this short spends under two hours in the air, which leaves almost nothing to claw back a late pushback with. Delay here is decided on the ground, in the turn, which is why the 5am–8am window matters as much as it does.
The return leg runs 81.0% on time across 1,688 flights, within 2 points of this direction. The two legs are scored separately because they usually differ; on this city pair they happen not to.
The sample behind these figures is 1,687 flights, enough that the headline rate is stable to within roughly a point. The hour-block and month splits divide that further, so read the thinner bars with more caution than the headline.
What to do with this
Booking American on PHX to LAS
Put together: the calendar is the biggest lever here, not the carrier or the hour. August runs 88.8% on time and June 74.5%, a swing of 14 points. If the dates move at all, move them out of June before you think about anything else. 1,671 completed flights over 12 months sit behind that.
