PSA on IND to PHL sits in the middle of the pack with a C−. Close to three flights in four arrive on time by the DOT's definition, 3 points worse than the national rate of 77.3%. The late ones land about 2.2 hours behind schedule. That rests on 487 flights. The strongest carrier on the route with a full sample, Republic Airways, flew 574 at 90.0% on time.

The US average over the same twelve months is 77.3%, so there is little to separate PSA on IND 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 IND to PHL

PSA flew 487 of the 1,596 flights on IND to PHL, about 31% of it. Its 74.8% on time is 6 points worse than the route as a whole, which runs 80.9%. Ranked by on-time rate it is last of three carriers on the route, where the range runs from Republic at 90.0% to PSA at 74.8%.

The choice of carrier is not cosmetic here. Republic Airways arrives on time 90.0% of the time; American Airlines manages 76.4%. Sample sizes sit next to every figure, because a two-point gap across 535 flights means less than a ten-point one.

PSA on IND to PHL did not run the same all year. Its best quarter was Jan–Mar 2026 at 80.2% on time and its weakest Oct–Dec 2025 at 65.4%, a swing of 15 points on roughly 122 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.

Delay causes

Why PSA runs late on this route

Late-arriving aircraft accounts for 60% of the 15,000 delay minutes carriers reported here, and the remaining four split what is left.

  • Late-arriving aircraft
    60%
  • National Airspace System
    27%
  • Carrier
    11%
  • Extreme weather
    2%
  • Security
    0%

60% 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 28 to one. The split is drawn from 14,824 reported delay minutes.

Cancellations run at 8.83%, against 1.89% 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

10.1% 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 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.

The return leg runs 77.5% on time across 489 flights, within 3 points 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. 487 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 IND to PHL

Put together: the delay figures matter less here than the 8.83% cancellation rate. A late arrival costs you about 2.2 hours; a cancelled flight costs you the day. Book the 5pm–8pm departure so there is still a schedule behind you if it goes wrong, and treat a same-day connection as optimistic. 444 completed flights over 12 months sit behind that.
