Historical statistics for July 2025 to June 2026, not live status. For today’s flights, check with PSA Airlines.
PSA on CMH to PHL lands a B−, level with the national rate of 77.6%. 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 is a workable record, not a spotless one. That rests on 346 flights. The strongest carrier on the route with a full sample, Republic Airways, flew 542 at 87.0% on time.
The US average over the same twelve months is 77.6%, so there is little to separate PSA on CMH 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 CMH to PHL, 1,378 flights
These figures cover 346 flights between July 2025 and June 2026. Beyond the headline rate, 8.3% 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 CMH to PHL
PSA flew 346 of the 1,378 flights on CMH to PHL, about 25% of it. Its 77.9% on time is 2 points worse than the route as a whole, which runs 79.6%. Ranked by on-time rate it is number two of three carriers on the route, where the range runs from Republic at 87.0% to American at 72.5%.
The choice of carrier is not cosmetic here. Republic Airways arrives on time 87.0% of the time; American Airlines manages 72.5%. Sample sizes sit next to every figure, because a two-point gap across 490 flights means less than a ten-point one.
| Airline | Flights | On time | Avg delay | Cancelled | Grade |

| Republic Airways | 542 | 87.0% | 58 min | 1.48% | A |

| American Airlines | 490 | 72.5% | 94 min | 3.47% | C− |
American Airlines cancels 3.5% 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.
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 24 points, against 15 points between the best and worst carrier. Each bar is the on-time rate for flights scheduled inside that window.
- 5am–8am9 flights—
- 8am–11am47 flights93.3%
- 11am–2pm117 flights81.6%
- 2pm–5pm64 flights70.7%
- 5pm–8pm109 flights69.3%
- 8pm–5am—
Scale runs 60% to 100%. Rows with fewer than 30 flights show a dash.
Book the morning departure. Flights leaving between 8am–11am arrive on time 93.3% of the time, against 69.3% for the evening window. That is 24 points of difference for no extra money, and it comes from the same aircraft having had no earlier flight to fall behind on. The 11am–2pm window is the busiest, with 117 flights scheduled in it.
Across the year
PSA on CMH to PHL through the year
- Jul–Sep 202566 flights81.2%
- Oct–Dec 202586 flights73.4%

Scale runs 65% to 90%. Rows with fewer than 30 flights show a dash.
Monthly volumes are too low here to break the year into twelve reliable readings. What the twelve-month total says is 77.9% on time across 346 flights.
PSA on CMH to PHL did not run the same all year. Its best quarter was Apr–Jun 2026 at 83.2% on time and its weakest Jan–Mar 2026 at 71.4%, a swing of 12 points on roughly 87 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, Friday is the strongest day at 83.6% on time and Wednesday the weakest at 71.7%. 12 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 70% of the 5,093 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.
- 70%Late-arriving aircraft
- 20%National Airspace System
- 8%Carrier
- 2%Extreme weather
70% 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 5,093 reported delay minutes here, that single category outweighs weather by 34 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 5,093 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 93.3% on time here.
Cancellations run at 5.49%, against 1.81% 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.
Connections and stage length
What a delay here costs
8.3% of arrivals land an hour or more late, close to the national 8.1%. That is the figure that decides a connection, and it says a 60 to 75 minute layover is reasonable here while anything under 45 minutes is a bet. Most delays on this route last a little over an hour, which a normal layover absorbs.
At 407 miles this is a short hop, and stage length matters more than it looks. A flight this short spends under two hours in the air, which leaves almost nothing to claw back a late pushback with. Delay here is decided on the ground, in the turn, which is why the 8am–11am window matters as much as it does.
The return leg is a different operation and performs like one: it runs 81.3% on time across 347 flights, 3 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 3 points of difference.
One caution: this is a thin sample. 346 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 CMH to PHL
Put together: the delay figures matter less here than the 5.49% cancellation rate. A late arrival costs you a little over an hour; 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. 326 completed flights over 12 months sit behind that.
