Historical statistics for July 2025 to June 2026, not live status. For today’s flights, check with PSA Airlines.

PSA on MCI to PHL lands a B−, about a point better than the national rate of 77.6%. About one flight in five arrives 15 minutes late or worse, and those flights are late by an hour and a half on average. That is a workable record, not a spotless one. That rests on 315 flights, with a median arrival 13 minutes early.

The US average over the same twelve months is 77.6%, so there is little to separate PSA on MCI 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 MCI to PHL, 903 flights

These figures cover 315 flights between July 2025 and June 2026. Beyond the headline rate, 9.4% 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 MCI to PHL

PSA flew 315 of the 903 flights on MCI to PHL, about 35% of it. Its 78.5% on time is 3 points worse than the route as a whole, which runs 81.0%. Ranked by on-time rate it is last of three carriers on the route, where the range runs from Republic at 87.5% to PSA at 78.5%. One 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 14 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–8am150 flights85.4%
8am–11am—
11am–2pm51 flights71.7%
2pm–5pm34 flights—
5pm–8pm80 flights82.9%
8pm–5am—

Scale runs 65% to 90%. Rows with fewer than 30 flights show a dash.

The weak window here is the middle of the day, not the evening: 11am–2pm runs 71.7% on time against 85.4% for 5am–8am. That shape usually means a departure bank rather than an accumulating delay, so the recovery later in the afternoon is real rather than noise. The 5am–8am window is the busiest, with 150 flights scheduled in it.

Monthly volumes are too low here to break the year into twelve reliable readings. What the twelve-month total says is 78.5% on time across 315 flights.

PSA on MCI to PHL did not run the same all year. Its best quarter was Apr–Jun 2026 at 88.0% on time and its weakest Jul–Sep 2025 at 57.6%, a swing of 30 points on roughly 79 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, Saturday is the strongest day at 83.3% on time and Sunday the weakest at 73.8%. 10 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 46% of the 6,115 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.

Extreme weather
5%

46% 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 6,115 reported delay minutes here, that single category outweighs weather by 9 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 6,115 reported delay minutes.

The largest share of delay minutes, 35%, falls under carrier control: crew scheduling, maintenance, fuelling, baggage. Unlike weather, that is a management outcome, and it is the category where the gap between two carriers on the same schedule is genuinely earned. It accounts for 2,161 of the 6,115 delay minutes reported here.

Cancellations run at 8.25%, against 1.81% nationally. That is about one flight in twelve 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. 9.4% 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 1,038 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 72.9% on time across 314 flights, 6 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 6 points of difference.

One caution: this is a thin sample. 315 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 MCI to PHL

Put together: the delay figures matter less here than the 8.25% 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. 288 completed flights over 12 months sit behind that.
