PSA Airlines at Philadelphia carries a cancellation problem, not just a delay problem: 4.3% of scheduled flights never operate, against 1.8% nationally. Of the ones that do fly, close to three flights in four arrive on time, worth a C− overall. The punctuality figure counts only flights that actually departed, so it flatters an operation that cancels this often. That rests on 16,135 flights, of which Delta Air Lines flew 6,458 at 82.3% on time.
Measured against the airport rather than the country, PSA Airlines runs half a point behind the 74.9% weighted average across all carriers at PHL. That is the comparison worth making: every operator here works the same runways, the same airspace and the same weather.

#5
Of 10 carriers clearing the floor at PHL
These figures cover 16,000 flights between June 2025 and May 2026. Beyond the headline rate, 12.0% 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.
Against the competition
Every carrier at PHL, ranked
The choice of carrier is not cosmetic here. Delta Air Lines arrives on time 82.3% of the time; Alaska Airlines manages 64.3%. Sample sizes sit next to every figure, because a two-point gap across 675 flights means less than a ten-point one.

PSA Airlines cancels 4.3% of what it schedules here, the highest in the table. A cancelled flight never appears in an on-time rate, so read that column alongside the punctuality one rather than after it.
Route by route
Where PSA Airlines flies from PHL
PSA Airlines operates 25 routes out of PHL with enough volume to report. Route records inside one carrier at one airport still spread widely, because a short shuttle and a transcontinental have very different exposure to a late inbound.

Departure window
Best time of day for this operation
Departure time matters more here than the choice of carrier. The gap between the best and worst window is 17 points, against 18 points between the best and worst carrier. Each bar is the on-time rate for flights scheduled inside that window.
- 5am–8am294 flights81.3%
- 8am–11am4,580 flights82.7%
- 11am–2pm2,196 flights76.4%
- 2pm–5pm2,812 flights71.2%
- 5pm–8pm3,859 flights66.1%
- 8pm–5am2,394 flights71.4%
Scale runs 60% to 90%. Rows with fewer than 30 flights show a dash.
Book the morning departure. Flights leaving between 8am–11am arrive on time 82.7% of the time, against 66.1% for the evening window. That is 17 points of difference for no extra money, and it comes from the same aircraft having had no earlier flight to fall behind on.
Across the year
Seasonal pattern
December is the weak month at 58.1% on time, against 87.0% 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.
Delay causes
What holds this operation up
- 52%Late-arriving aircraft
- 25%Carrier
- 15%National Airspace System
- 8%Extreme weather
- 0%Security
52% 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 361,000 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.
Cancellations run at 4.32%, against 1.80% nationally. That is about one flight in 25 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.
For anyone connecting, the number to weigh is not the on-time rate but the tail behind it. 12.0% of arrivals land a full hour or more behind schedule, against 8.2% 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.
16,135 flights sit behind these numbers, which is a large enough sample that the headline rate is not moving on noise. Where a sub-group falls below 30 flights the site shows a dash instead of a percentage.
Put together: the delay figures matter less here than the 4.32% cancellation rate. A late arrival costs you an hour and a half; 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.
Common questions
PSA Airlines at PHL
How often is PSA Airlines at PHL delayed?
About one flight in four arrive at least 15 minutes late, which is the Department of Transportation's definition of a delayed arrival. That works out to 25.8% of the 16,135 flights in this analysis, against 22.6% nationally. Delayed flights are late by an hour and a half on average.
Which airline is most reliable on PSA Airlines at PHL?
Delta Air Lines leads at 82.3% on time across 6,458 flights. Alaska Airlines is at the other end on 64.3%, a gap of 18 points. Sample size matters as much as the percentage: a rate built from a few hundred flights moves around far more than one built from ten thousand.
What time of day has the fewest delays on PSA Airlines at PHL?
The 8am–11am departure window is the strongest at 82.7% on time. The 5pm–8pm window is the weakest at 66.1%, 17 points behind. Later departures inherit delays from earlier flights the same aircraft has already flown, which is why the curve slopes the way it does.
How bad are December delays on PSA Airlines at PHL?
December is the weakest month at 58.1% on time, compared with 87.0% in September. Across the year that is 29 points between the best and worst months. Moving flexible dates out of that month is one of the few things that reliably helps.
