Historical statistics for July 2025 to June 2026, not live status. For today’s flights, check with American Airlines.
American on LAS to PHX lands a B+, 3 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 a little over an hour on average. That is a workable record, not a spotless one. That rests on 1,688 flights. The strongest carrier on the route with a full sample, Frontier Airlines, flew 865 at 79.5% on time.
The US average over the same twelve months is 77.6%, so there is little to separate American on LAS to PHX from the country as a whole. The variation that matters here is internal: which carrier, and what time of day.

Every carrier on LAS to PHX, 6,025 flights
These figures cover 1,688 flights between July 2025 and June 2026. The median arrival is 9 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
American against every carrier on LAS to PHX
American flew 1,688 of the 6,025 flights on LAS to PHX, about 28% of it. Its 81.0% on time is 3 points better than the route as a whole, which runs 78.2%. Ranked by on-time rate it is number four of six carriers on the route, where the range runs from Spirit at 100.0% to Southwest at 76.4%. Three of those carriers flew fewer than 365 flights here, so treat their positions as rough.
The two carriers here are closely matched: 3 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 79.5%, 3 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 25 points, against 3 points between the best and worst carrier. Each bar is the on-time rate for flights scheduled inside that window.
- 5am–8am348 flights91.6%
- 8am–11am332 flights91.1%
- 11am–2pm424 flights79.3%
- 2pm–5pm327 flights70.2%
- 5pm–8pm120 flights74.8%
- 8pm–5am137 flights66.2%
Scale runs 60% to 95%. Rows with fewer than 30 flights show a dash.
Book the early departure. Flights leaving between 5am–8am arrive on time 91.6% of the time, against 66.2% for the overnight window. That is 25 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 424 flights scheduled in it.
Across the year
American on LAS to PHX through the year
January is the weak month at 71.6% on time, against 87.3% in September. 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. October was the busiest month here, with 159 flights.
Across the week, Wednesday is the strongest day at 86.7% on time and Sunday the weakest at 74.6%. 12 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 62% of the 25,000 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.
- 62%Late-arriving aircraft
- 26%Carrier
- 10%National Airspace System
- 2%Extreme weather
62% 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 25,000 reported delay minutes here, that single category outweighs weather by 40 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 24,825 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 91.6% 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
7.8% 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 a little over 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 79.1% on time across 1,687 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 1,688 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 LAS to PHX
Put together: the calendar is the biggest lever here, not the carrier or the hour. September runs 87.3% on time and January 71.6%, a swing of 16 points. If the dates move at all, move them out of January before you think about anything else. 1,672 completed flights over 12 months sit behind that.
