American on PHX to MRY sits in the middle of the pack with a B. Close to three flights in four arrive on time by the DOT's definition, 2 points worse than the national rate of 77.6%. The late ones land a little over an hour behind schedule. That rests on 266 flights, with a median arrival 4 minutes early.

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

These figures cover 266 flights between July 2025 and June 2026. Beyond the headline rate, 11.2% 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 MRY

American flew 266 of the 1,374 flights on PHX to MRY, about 19% of it. Its 75.7% on time is 3 points worse than the route as a whole, which runs 78.9%. Ranked by on-time rate it is last of three carriers on the route, where the range runs from Envoy at 86.1% to American at 75.7%. 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 23 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–8am—
8am–11am34 flights84.8%
11am–2pm54 flights63.0%
2pm–5pm52 flights86.3%
5pm–8pm79 flights76.3%
8pm–5am47 flights71.1%

Scale runs 55% to 90%. Rows with fewer than 30 flights show a dash.

The weak window here is the middle of the day, not the evening: 11am–2pm runs 63.0% on time against 86.3% for 2pm–5pm. That shape usually means a departure bank rather than an accumulating delay, so the recovery later in the afternoon is real rather than noise. The 5pm–8pm window is the busiest, with 79 flights scheduled in it.

Monthly volumes are too low here to break the year into twelve reliable readings. What the twelve-month total says is 75.7% on time across 266 flights.

American on PHX to MRY did not run the same all year. Its best quarter was Apr–Jun 2026 at 89.2% on time and its weakest Jul–Sep 2025 at 71.2%, a swing of 18 points on roughly 67 flights a quarter. The twelve-month rate averages over that, so if you are flying in a weak quarter the quarter's own figure is the better guide.

Across the week, Saturday is the strongest day at 84.2% on time and Monday the weakest at 69.2%. 15 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 49% of the 4,667 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.

43%
National Airspace System

Extreme weather
1%

49% 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 4,667 reported delay minutes here, that single category outweighs weather by 49 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 4,667 reported delay minutes.

The largest share of delay minutes, 43%, 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 1,989 of the 4,667 delay minutes reported here.

Cancellations sit at 1.50% against a national 1.81%, which is ordinary. Diversions add another 1.13%.

Connections and stage length

What a delay here costs

For anyone connecting, the number to weigh is not the on-time rate but the tail behind it. 11.2% of arrivals land a full hour or more behind schedule, against 8.1% nationally. A 45-minute layover does not survive that, and no amount of walking quickly changes it. Ninety minutes is the honest minimum here, and two hours if the onward flight is on a separate ticket.

The 598 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 81.5% on time across 267 flights, 6 points above 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 6 points of difference.

One caution: this is a thin sample. 266 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 PHX to MRY

Put together: treat all of this as provisional. 266 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 75.7% headline is the most reliable number on the page; the hour and month splits below it are built on a few dozen flights each. 259 completed flights over 12 months sit behind that.
