American on PHX to MRY lands a B, about a point better than the national rate of 77.3%. Roughly one flight in five arrives 15 minutes late or worse, and those flights are late by a little over an hour on average. That rests on 249 flights, with a median arrival 5 minutes early.

The US average over the same twelve months is 77.3%, 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.

Ranked by on-time rate it is last of three carriers on the route, where the range runs from Envoy at 88.5% to American at 78.1%. 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 26 points, against half a point between the best and worst carrier.

8am–11am34 flights84.8%
11am–2pm31 flights61.3%
2pm–5pm79 flights87.2%
5pm–8pm68 flights72.3%
8pm–5am37 flights77.1%

Scale runs 55% to 95%. 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 61.3% on time against 87.2% 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 2pm–5pm window is the busiest, with 79 flights scheduled in it.

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 Jan–Mar 2026 at 73.5%, a swing of 16 points on roughly 62 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.

Delay causes

Why American runs late on this route

Late-arriving aircraft accounts for 54% of the 3,710 delay minutes carriers reported here, and the remaining four split what is left.

Late-arriving aircraft
54%
Carrier
37%
National Airspace System
9%

54% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. Across 3,710 reported delay minutes here, that single category outweighs weather by 54 to one. The split is drawn from 3,710 reported delay minutes.

The largest share of delay minutes, 37%, falls under carrier control: crew scheduling, maintenance, fuelling, baggage. It accounts for 1,385 of the 3,710 delay minutes reported here.

Cancellations sit at 1.61% against a national 1.89%, which is ordinary. Diversions add another 1.20%.

Connections and stage length

What a delay here costs

9.5% of arrivals land a full hour or more behind schedule, against 8.3% nationally. Ninety minutes is the honest minimum for a connection 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.

The return leg is a different operation and performs like one: it runs 82.7% on time across 251 flights, 5 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 5 points of difference.

One caution: this is a thin sample. 249 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. 249 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 78.1% headline is the most reliable number on the page; the hour and month splits below it are built on a few dozen flights each. 242 completed flights over 12 months sit behind that.
