Historical statistics for September 2025 to August 2026, not live status. For today’s flights, check with PSA Airlines.
PSA on MSP to PHL lands a B−, level with the national rate of 77.3%. Roughly one flight in four arrives 15 minutes late or worse, and those flights are late by close to two hours on average. That rests on 617 flights, with a median arrival 11 minutes early.
The US average over the same twelve months is 77.3%, so there is little to separate PSA on MSP to PHL from the country as a whole. The variation that matters here is internal: which carrier, and what time of day.

Carrier by carrier
PSA against every carrier on MSP to PHL
PSA flew 617 of the 2,085 flights on MSP to PHL, about 30% of it. Its 77.1% on time is 2 points worse than the route as a whole, which runs 79.4%. Ranked by on-time rate it is number three of five carriers on the route, where the range runs from Republic at 81.5% to American at 73.1%. Three 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 19 points, against half a point between the best and worst carrier.
- 5am–8am270 flights85.7%
- 8am–11am1 flights—
- 11am–2pm230 flights68.2%
- 2pm–5pm62 flights66.7%
- 5pm–8pm54 flights82.0%
- 8pm–5am—
Scale runs 60% to 90%. Rows with fewer than 30 flights show a dash.
Book the early departure. Flights leaving between 5am–8am arrive on time 85.7% of the time, against 66.7% for the afternoon 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 5am–8am window is the busiest, with 270 flights scheduled in it.
Across the year
PSA on MSP to PHL through the year
December is the weak month at 61.1% on time, against 87.7% in June. 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. April was the busiest month here, with 84 flights.
Across the week, Tuesday is the strongest day at 79.8% on time and Saturday the weakest at 72.6%, a spread of 7 points.

The worst days
Worst days for PSA on MSP to PHL
The latest arrival of the period was on 26 November 2025, 23 hours 14 minutes behind schedule; most of its delay minutes were filed as a late-arriving aircraft. On three of the five worst days the largest share was filed as carrier-caused (crew, maintenance, fuelling, baggage).
| Date | Arrived late by | Largest filed cause |
|---|---|---|
| 26 November 2025 | 23 hours 14 minutes | Late-arriving aircraft |
| 5 March 2026 | 18 hours 3 minutes | Carrier |
| 27 January 2026 | 12 hours 29 minutes | Carrier |

Delay causes
Why PSA runs late on this route
Late-arriving aircraft accounts for 45% of the 15,000 delay minutes carriers reported here, and the remaining four split what is left.
- 45%Late-arriving aircraft
- 39%Carrier
- 13%National Airspace System
- 2%Extreme weather
- 0%Security
45% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. Across 15,000 reported delay minutes here, that single category outweighs weather by 18 to one. The split is drawn from 14,851 reported delay minutes.
The largest share of delay minutes, 39%, falls under carrier control: crew scheduling, maintenance, fuelling, baggage. It accounts for 5,822 of the 15,000 delay minutes reported here.
Cancellations run at 6.97%, against 1.89% nationally. That is about one flight in fifteen 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
10.9% 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 981 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 73.9% on time across 618 flights, 3 points below 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. 617 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 MSP to PHL
Put together: the delay figures matter less here than the 6.97% cancellation rate. A late arrival costs you close to two hours; 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. 571 completed flights over 12 months sit behind that.
