These figures cover 342 flights between July 2025 and June 2026. The median arrival is 7 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 DTW to PIT

Republic flew 342 of the 1,006 flights on DTW to PIT, about 34% of it. Its 85.3% on time is 7 points better than the route as a whole, which runs 78.2%. Ranked by on-time rate it is first of three carriers on the route, where the range runs from Republic at 85.3% to SkyWest at 72.7%. 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 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 342 flights.

There are not enough flights in each departure window to split Republic's DTW to PIT record by time of day without the percentages moving on noise. The headline rate of 85.3% is the reliable figure here.

Across the year

Republic on DTW to PIT through the year

Jul–Sep 2025119 flights90.8%
Oct–Dec 2025103 flights77.5%
Jan–Mar 202610 flights—
Apr–Jun 2026110 flights90.9%

Scale runs 70% to 95%. Rows with fewer than 30 flights show a dash.

Monthly volumes are too low here to break the year into twelve reliable readings. What the twelve-month total says is 85.3% on time across 342 flights.

Republic on DTW to PIT did not run the same all year. Its best quarter was Apr–Jun 2026 at 90.9% on time and its weakest Oct–Dec 2025 at 77.5%, a swing of 13 points on roughly 114 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, Wednesday is the strongest day at 91.5% on time and Sunday the weakest at 79.6%. 12 points is a smaller lever than departure hour, but it is free.

Delay causes

Why Republic runs late on this route

One category carries most of the weight here. Carrier accounts for 52% of the 2,908 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.

National Airspace System

Late-arriving aircraft
20%
Extreme weather
4%

The largest share of delay minutes, 52%, 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 1,501 of the 2,908 delay minutes reported here. The split is drawn from 2,908 reported delay minutes.

Cancellations are rare at 0.29%, below the national 1.81% and low enough to earn the plus on the grade. Roughly one flight in 100 is called off; the risk here is arriving late, not not arriving.

Connections and stage length

What a delay here costs

Badly late arrivals are rare here: only 4.4% 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 201 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 8am–11am window matters as much as it does.

The return leg runs 83.5% on time across 343 flights, within 2 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. 342 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 DTW to PIT

Put together: treat all of this as provisional. 342 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 85.3% headline is the most reliable number on the page; the hour and month splits below it are built on a few dozen flights each. 341 completed flights over 12 months sit behind that.
