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

Republic on BOS to PIT lands a B, 3 points better than the national rate of 77.6%. About 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 1,144 flights, with a median arrival 11 minutes early.

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

Every carrier on BOS to PIT, 2,152 flights

These figures cover 1,144 flights between July 2025 and June 2026. The median arrival is 11 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 BOS to PIT

Republic flew 1,144 of the 2,152 flights on BOS to PIT, most of the route. Its 80.6% on time is 2 points better than the route as a whole, which runs 78.7%. Ranked by on-time rate it is first of two carriers on the route, where the range runs from Republic at 80.6% to JetBlue at 76.6%.

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 matters more here than the choice of carrier. The gap between the best and worst window is 30 points, against half a point between the best and worst carrier. Each bar is the on-time rate for flights scheduled inside that window.

5am–8am94 flights88.3%
8am–11am244 flights91.7%
11am–2pm158 flights90.5%
2pm–5pm322 flights80.7%
5pm–8pm33 flights87.9%
8pm–5am293 flights61.8%

Scale runs 55% to 95%. Rows with fewer than 30 flights show a dash.

The 8pm–5am window is where this operation falls apart: 61.8% on time, against 91.7% for the 8am–11am slot. By evening the aircraft flying these rotations have absorbed a full day of small delays and there is no slack left to recover in. The 2pm–5pm window is the busiest, with 322 flights scheduled in it.

Across the year

Republic on BOS to PIT through the year

Darker means more delays. Figures are on-time percentages.August best, September worst

Delays peak in September, when the on-time rate falls to 69.4%. August is the strongest month at 90.7%. Moving a flexible trip across that boundary buys 21 points. May was the busiest month here, with 114 flights.

Across the week, Saturday is the strongest day at 89.6% on time and Thursday the weakest at 71.4%. 18 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. Late-arriving aircraft accounts for 55% of the 14,000 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.

Extreme weather
1%

55% 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 14,000 reported delay minutes here, that single category outweighs weather by 55 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 14,097 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 91.7% on time here.

Cancellations sit at 2.45% against a national 1.81%, which is ordinary. Diversions add another 0.00%.

Connections and stage length

What a delay here costs

7.9% 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.

At 496 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 81.8% on time across 1,144 flights, within about a point of this direction. The two legs are scored separately because they usually differ; on this city pair they happen not to.

The sample behind these figures is 1,144 flights, enough that the headline rate is stable to within roughly a point. The hour-block and month splits divide that further, so read the thinner bars with more caution than the headline.

What to do with this

Booking Republic on BOS to PIT

Put together: the calendar is the biggest lever here, not the carrier or the hour. August runs 90.7% on time and September 69.4%, a swing of 21 points. If the dates move at all, move them out of September before you think about anything else. 1,116 completed flights over 12 months sit behind that.
