Republic on PIT to PHL earns an A. Close to nine flights in ten arrive inside the 15-minute window the DOT uses to define an on-time arrival, which puts it 12 points better than the national rate of 77.6%. When something does go wrong the average delay runs roughly 45 minutes. That rests on 305 flights, with a median arrival 12 minutes early.

Set against the rest of the country, Republic's PIT to PHL record is 12 points better than the US average of 77.6%. That gap is worth roughly 121 fewer late arrivals for every thousand flights.

Every carrier on PIT to PHL, 1,226 flights

These figures cover 305 flights between July 2025 and June 2026. The median arrival is 12 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

Republic against every carrier on PIT to PHL

Republic flew 305 of the 1,226 flights on PIT to PHL, about 25% of it. Its 89.7% on time is 13 points better than the route as a whole, which runs 77.2%. Ranked by on-time rate it is first of four carriers on the route, where the range runs from Republic at 89.7% to Frontier at 61.8%. Two 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 Republic 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 305 flights.

5am–8am191 flights92.5%
8am–11am63 flights87.3%
11am–2pm46 flights87.0%
2pm–5pm—
5pm–8pm5 flights—
8pm–5am—

Scale runs 80% to 100%. 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 87.0% on time against 92.5% 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 191 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 89.7% on time across 305 flights.

Quarter by quarter Republic on PIT to PHL held fairly steady: 90.4% in Oct–Dec 2025, 92.5% in Jan–Mar 2026 and 86.0% in Apr–Jun 2026. A spread of 7 points is about what a sample of this size moves on its own, so the annual figure is a fair summary.

Across the week, Wednesday is the strongest day at 97.7% on time and Sunday the weakest at 75.0%. 23 points is a smaller lever than departure hour, but it is free.

Delay causes

Why Republic 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 1,438 reported delay minutes.

National Airspace System
37%
Late-arriving aircraft
21%
Carrier
21%
Extreme weather
21%

Extreme weather accounts for 21% of delay minutes, well above the single-digit share typical across the system. Weather delays are lumpy: they arrive as whole bad days rather than as a steady drag, so the monthly strip above is the more useful view of the risk. The national share is 6%, so this operation carries roughly 3.3 times the usual weather exposure. The split is drawn from 1,438 reported delay minutes.

37% of delay minutes are charged to the National Airspace System: air traffic volume, runway configuration, ground stops. No carrier can price its way out of that, which is why airport choice moves the number here more than carrier choice does. That is 526 minutes out of 1,438, against a national NAS share of 21%.

Cancellations sit at 1.64% against a national 1.81%, which is ordinary. Diversions add another 0.00%.

Connections and stage length

What a delay here costs

Badly late arrivals are rare here: only 2.3% land an hour or more behind schedule, against 8.1% nationally. Connections built on this flight are about as safe as US domestic connections get, though a cancelled flight still ignores every layover you give it.

At 268 miles this is a short hop, and stage length matters more than it looks. A flight this short spends under two hours in the air, which leaves almost nothing to claw back a late pushback with. Delay here is decided on the ground, in the turn, which is why the 5am–8am window matters as much as it does.

The return leg is a different operation and performs like one: it runs 82.7% on time across 305 flights, 7 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 7 points of difference.

One caution: this is a thin sample. 305 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 Republic on PIT to PHL

Put together: treat all of this as provisional. 305 flights over twelve months is enough to clear this site's floor and not enough to be confident to better than a couple of points. The 89.7% headline is the most reliable number on the page; the hour and month splits below it are built on a few dozen flights each. 300 completed flights over 12 months sit behind that.
