Historical statistics for July 2025 to June 2026, not live status. For today’s flights, check with American Airlines.

American on BNA to PHX 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 close to two hours on average. That is a workable record, not a spotless one. That rests on 566 flights, with a median arrival 6 minutes early.

The US average over the same twelve months is 77.6%, so there is little to separate American on BNA to PHX from the country as a whole. The variation that matters here is internal: which carrier, and what time of day.

These figures cover 566 flights between July 2025 and June 2026. The median arrival is 6 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 BNA to PHX

American flew 566 of the 2,370 flights on BNA to PHX, about 24% of it. Its 79.1% on time is about level with the route as a whole at 78.5%. Ranked by on-time rate it is number two of three carriers on the route, where the range runs from Frontier at 100.0% to Southwest at 78.2%. One of those carriers flew fewer than 365 flights here, so treat their positions as rough.

Only one carrier clears this site's 365-flight floor here, so there is no comparison to draw. The table below is the full picture.

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 30 points, against half a point between the best and worst carrier. Each bar is the on-time rate for flights scheduled inside that window.

  • 5am–8am363 flights87.2%
  • 8am–11am
  • 11am–2pm
  • 2pm–5pm61 flights57.4%
  • 5pm–8pm139 flights68.8%
  • 8pm–5am3 flights

Scale runs 50% to 95%. Rows with fewer than 30 flights show a dash.

Book the early departure. Flights leaving between 5am–8am arrive on time 87.2% of the time, against 57.4% for the afternoon window. That is 30 points of difference for no extra money, and it comes from the same aircraft having had no earlier flight to fall behind on. The 5am–8am window is the busiest, with 363 flights scheduled in it.

Darker means more delays. Figures are on-time percentages.July best, October worst

Delays peak in October, when the on-time rate falls to 63.2%. July is the strongest month at 84.4%. Moving a flexible trip across that boundary buys 21 points. March was the busiest month here, with 60 flights.

Across the week, Tuesday is the strongest day at 90.6% on time and Sunday the weakest at 68.5%. 22 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 53% of the 13,000 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.

  • Late-arriving aircraft
    53%
  • Carrier
    42%
  • National Airspace System
    4%
  • Extreme weather
    1%

53% 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 13,000 reported delay minutes here, that single category outweighs weather by 53 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 13,250 reported delay minutes.

The largest share of delay minutes, 42%, falls under carrier control: crew scheduling, maintenance, fuelling, baggage. Unlike weather, that is a management outcome, and it is the category where the gap between two carriers on the same schedule is genuinely earned. It accounts for 5,523 of the 13,000 delay minutes reported here.

Cancellations sit at 1.06% against a national 1.81%, which is ordinary. Diversions add another 0.00%.

Connections and stage length

What a delay here costs

7.1% 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 close to two hours, which a normal layover absorbs.

The 1,449 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. It is also long enough that the aircraft usually flies three or four legs a day rather than six, which slows how fast delay compounds.

The return leg is a different operation and performs like one: it runs 71.7% on time across 566 flights, 7 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 7 points of difference.

One caution: this is a thin sample. 566 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 American on BNA to PHX

Put together: treat all of this as provisional. 566 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 79.1% headline is the most reliable number on the page; the hour and month splits below it are built on a few dozen flights each. 560 completed flights over 12 months sit behind that.
