Historical statistics for July 2025 to June 2026, not live status. For today’s flights, check with PSA Airlines.
PSA on JAX to PHL lands a B−, about a point worse than the national rate of 77.6%. About one flight in four 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 472 flights, with a median arrival 11 minutes early.
The US average over the same twelve months is 77.6%, so there is little to separate PSA on JAX to PHL from the country as a whole. The variation that matters here is internal: which carrier, and what time of day.

Every carrier on JAX to PHL, 1,553 flights
These figures cover 472 flights between July 2025 and June 2026. Beyond the headline rate, 13.8% 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
PSA against every carrier on JAX to PHL
PSA flew 472 of the 1,553 flights on JAX to PHL, about 30% of it. Its 76.8% on time is 2 points worse than the route as a whole, which runs 78.5%. Ranked by on-time rate it is number three of four carriers on the route, where the range runs from Republic at 91.5% to Frontier at 72.5%. Two 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 PSA 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. Each bar is the on-time rate for flights scheduled inside that window.
- 5am–8am6 flights—
- 8am–11am186 flights85.1%
- 11am–2pm29 flights—
- 2pm–5pm148 flights59.4%
- 5pm–8pm103 flights80.9%
- 8pm–5am—
Scale runs 50% to 90%. Rows with fewer than 30 flights show a dash.
Book the morning departure. Flights leaving between 8am–11am arrive on time 85.1% of the time, against 59.4% for the afternoon 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 8am–11am window is the busiest, with 186 flights scheduled in it.
Across the year
PSA on JAX to PHL through the year
August is the worst month at 55.9% on time, 34 points below September, the best at 90.0%. 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. March was the busiest month here, with 62 flights.
Across the week, Wednesday is the strongest day at 86.9% on time and Sunday the weakest at 67.7%. 19 points is a smaller lever than departure hour, but it is free.
Delay causes
Why PSA runs late on this route
One category carries most of the weight here. Late-arriving aircraft accounts for 63% of the 11,000 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.
- 63%Late-arriving aircraft
- 16%Carrier
- 13%National Airspace System
- 9%Extreme weather
63% 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 11,000 reported delay minutes here, that single category outweighs weather by 7 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 11,287 reported delay minutes.
The practical consequence: the 8am–11am departure is the one that starts clean. Its aircraft has no earlier leg to be late from, which is exactly why that window shows 85.1% on time here.
Cancellations run at 5.08%, against 1.81% nationally. That is about one flight in twenty cancelled outright. A cancelled flight is invisible in every on-time figure on this page, so the punctuality numbers above describe only the flights that actually operated.
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. 13.8% 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 742 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 81.7% on time across 473 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. 472 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 PSA on JAX to PHL
Put together: the delay figures matter less here than the 5.08% cancellation rate. A late arrival costs you close to two hours; a cancelled flight costs you the day. Book the 8am–11am departure so there is still a schedule behind you if it goes wrong, and treat a same-day connection as optimistic. 448 completed flights over 12 months sit behind that.
