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

PSA on PHL to IND 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 about an hour on average. That is a workable record, not a spotless one. That rests on 338 flights. The strongest carrier on the route with a full sample, Republic Airways, flew 601 at 79.9% on time.

The US average over the same twelve months is 77.6%, so there is little to separate PSA on PHL to IND from the country as a whole. The variation that matters here is internal: which carrier, and what time of day.

Every carrier on PHL to IND, 1,549 flights

These figures cover 338 flights between July 2025 and June 2026. The median arrival is 9 minutes early, which is the part an average hides: most flights here are fine, and the on-time rate is decided by a tail of badly late ones. On-time means under 15 minutes late, the DOT's own threshold.

Carrier by carrier

PSA against every carrier on PHL to IND

PSA flew 338 of the 1,549 flights on PHL to IND, about 22% of it. Its 78.0% on time is 2 points better than the route as a whole, which runs 75.9%. Ranked by on-time rate it is number two of three carriers on the route, where the range runs from Republic at 79.9% to American at 71.0%.

The choice of carrier is not cosmetic here. Republic Airways arrives on time 79.9% of the time; American Airlines manages 71.0%. Sample sizes sit next to every figure, because a two-point gap across 610 flights means less than a ten-point one.

Republic Airways cancels 4.0% 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 11 points, against 9 points between the best and worst carrier. Each bar is the on-time rate for flights scheduled inside that window.

5am–8am—
8am–11am180 flights81.7%
11am–2pm65 flights70.8%
2pm–5pm73 flights76.1%
5pm–8pm1 flights—
8pm–5am19 flights—

Scale runs 60% to 85%. 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 70.8% on time against 81.7% for 8am–11am. 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 8am–11am window is the busiest, with 180 flights scheduled in it.

Oct–Dec 202553 flights64.2%

Monthly volumes are too low here to break the year into twelve reliable readings. What the twelve-month total says is 78.0% on time across 338 flights.

PSA on PHL to IND did not run the same all year. Its best quarter was Apr–Jun 2026 at 81.9% on time and its weakest Oct–Dec 2025 at 64.2%, a swing of 18 points on roughly 113 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, Tuesday is the strongest day at 88.6% on time and Sunday the weakest at 69.2%. 19 points is a smaller lever than departure hour, but it is free.

Delay causes

Why PSA runs late on this route

Carriers report a reason for every delay minute they cause, in five DOT categories. The split below is by minutes, not by number of flights, so a handful of very long weather delays weighs as much as many short ones. It covers 4,639 reported delay minutes.

Late-arriving aircraft
41%
Carrier
33%
National Airspace System
20%
Extreme weather
6%

41% 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 4,639 reported delay minutes here, that single category outweighs weather by 6 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 4,639 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 81.7% on time here.

Cancellations run at 5.92%, against 1.81% nationally. That is roughly 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

7.5% 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 about an hour, which a normal layover absorbs.

The 588 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 runs 77.6% on time across 335 flights, within half a point of this direction. The two legs are scored separately because they usually differ; on this city pair they happen not to.

One caution: this is a thin sample. 338 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 PHL to IND

Put together: the delay figures matter less here than the 5.92% cancellation rate. A late arrival costs you about 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. 318 completed flights over 12 months sit behind that.
