Historical statistics for September 2025 to August 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 77.3%. Roughly one flight in four arrives 15 minutes late or worse, and those flights are late by a little over an hour on average. That rests on 489 flights. The strongest carrier on the route with a full sample, Republic Airways, flew 571 at 80.6% on time.
The US average over the same twelve months is 77.3%, 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.

Carrier by carrier
PSA against every carrier on PHL to IND
PSA flew 489 of the 1,594 flights on PHL to IND, about 31% of it. Its 77.5% on time is about level with the route as a whole at 76.3%. Ranked by on-time rate it is number two of three carriers on the route, where the range runs from Republic at 80.6% to American at 70.6%.
The choice of carrier is not cosmetic here. Republic Airways arrives on time 80.6% of the time; American Airlines manages 70.6%. Sample sizes sit next to every figure, because a two-point gap across 534 flights means less than a ten-point one.
| Airline | Flights | On time | Avg delay | Cancelled | Grade |
|---|---|---|---|---|---|
| Republic Airways | 571 | 80.6% | 87 min | 3.33% | B− |
| PSA Airlines (this page) | 489 | 77.5% | 76 min | 7.16% | B− |
| American Airlines | 534 | 70.6% | 74 min | 2.62% | C |
Republic Airways cancels 3.3% 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 is the single lever a traveller controls, and it moves the odds more than most people expect. Each bar below is the on-time rate for flights scheduled to leave inside that window, across 489 flights.

- 8am–11am292 flights81.2%
- 11am–2pm64 flights71.9%

Scale runs 65% to 85%. Rows with fewer than 30 flights show a dash.
Book the morning departure. Flights leaving between 8am–11am arrive on time 81.2% of the time, against 71.6% for the afternoon window. That is 10 points of difference for no extra money, and it comes from the same aircraft having had no earlier flight to fall behind on. The 8am–11am window is the busiest, with 292 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 77.5% on time across 489 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 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.
Across the week, Tuesday is the strongest day at 86.4% on time and Sunday the weakest at 70.5%, a spread of 16 points.

Share of 454 completed flights by arrival against schedule.
27 of 105 late departures made up the time and arrived on time, 26% of them. In the other direction, 24 flights left on time yet arrived 15 minutes late or more, so that delay built up after pushback: in the air, in a holding pattern or on the ground at IND.
The worst days
Worst days for PSA on PHL to IND
The latest arrival of the period was on 6 July 2026, 7 hours 11 minutes behind schedule; most of its delay minutes were filed as a late-arriving aircraft. Three of the five worst days fell in July 2026.
| Date | Arrived late by | Largest filed cause |
|---|---|---|
| 6 July 2026 | 7 hours 11 minutes | Late-arriving aircraft |

Delay causes
Why PSA runs late on this route
Late-arriving aircraft accounts for 44% of the 7,785 delay minutes carriers reported here, and the remaining four split what is left.
- 44%Late-arriving aircraft
- 29%Carrier
- 19%National Airspace System
- 5%Extreme weather
- 2%Security
44% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. Across 7,785 reported delay minutes here, that single category outweighs weather by 8 to one. The split is drawn from 7,785 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 81.2% on time here.
Cancellations run at 7.16%, 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
8.6% of arrivals land an hour or more late, close to the national 8.3%, so 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.
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 74.8% on time across 487 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. 489 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 7.16% 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. 454 completed flights over 12 months sit behind that.
