PSA Airlines at Philadelphia carries a cancellation problem, not just a delay problem: 5.5% of scheduled flights never operate, against 1.9% 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 18,372 flights, of which Delta Air Lines flew 6,525 at 82.2% on time.
Measured against the airport rather than the country, PSA Airlines runs 2 points behind the 75.3% 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.

Against the competition
Every carrier at PHL, ranked
The choice of carrier is not cosmetic here. Delta Air Lines arrives on time 82.2% of the time; Alaska Airlines manages 67.3%. Sample sizes sit next to every figure, because a two-point gap across 768 flights means less than a ten-point one.

Spirit Airlines cancels 5.7% 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 19 points, against 15 points between the best and worst carrier.
- 5am–8am353 flights85.2%
- 8am–11am5,246 flights81.9%
- 11am–2pm2,237 flights76.1%
- 2pm–5pm3,579 flights69.2%
- 5pm–8pm4,045 flights66.5%
- 8pm–5am2,912 flights69.7%
Scale runs 60% to 90%.
Book the early departure. Flights leaving between 5am–8am arrive on time 85.2% of the time, against 66.5% for the evening window. That is 19 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 5,246 flights scheduled in it.
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. August was the busiest month here, with 2,117 flights.
Delay causes
What holds this operation up
- 49%Late-arriving aircraft
- 26%Carrier
- 15%National Airspace System
- 9%Extreme weather
- 0%Security
49% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. Across 403,000 reported delay minutes here, that single category outweighs weather by 6 to one. The split is drawn from 402,828 reported delay minutes.
Cancellations run at 5.53%, against 1.89% nationally. That is roughly 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.
12.4% 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.
18,372 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 5.53% cancellation rate. A late arrival costs you an hour and a half; a cancelled flight costs you the day. Book the 5am–8am departure so there is still a schedule behind you if it goes wrong, and treat a same-day connection as optimistic. 17,312 completed flights over 12 months sit behind that.
Common questions
PSA Airlines at PHL
How often is PSA Airlines at PHL delayed?
About one flight in four arrives at least 15 minutes late, which is the Department of Transportation's definition of a delayed arrival. That works out to 26.4% of the 18,372 flights in this analysis, against 22.7% 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 82.2% on time across 6,525 flights. Alaska Airlines is at the other end on 67.3%, a gap of 15 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 5am–8am departure window is the strongest at 85.2% on time. The 5pm–8pm window is the weakest at 66.5%, 19 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.
