Republic on GSO to DCA sits in the middle of the pack with a B. Close to three flights in four arrive on time by the DOT's definition, 2 points worse than the national rate of 77.6%. The late ones land about an hour behind schedule. That rests on 114 flights, with a median arrival 4 minutes early.

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

Every carrier on GSO to DCA, 800 flights

These figures cover 114 flights between July 2025 and June 2026. Beyond the headline rate, 9.1% of arrivals land a full hour or more behind schedule. That is the number that wrecks a connection, and it is not visible in an on-time percentage alone.

Carrier by carrier

Republic against every carrier on GSO to DCA

Republic flew 114 of the 800 flights on GSO to DCA, about 14% of it. Its 75.5% on time is 3 points better than the route as a whole, which runs 72.7%. Ranked by on-time rate it is number two of three carriers on the route, where the range runs from Envoy at 75.6% to PSA at 70.4%. 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 114 flights.

There are not enough flights in each departure window to split Republic's GSO to DCA record by time of day without the percentages moving on noise. The headline rate of 75.5% is the reliable figure here.

Across the year

Republic on GSO to DCA through the year

Jul–Sep 20254 flights—
Oct–Dec 202553 flights75.0%
Jan–Mar 202633 flights76.7%
Apr–Jun 202624 flights—

Scale runs 65% to 80%. 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 75.5% on time across 114 flights.

Split by quarter, Republic on GSO to DCA logged 4 flights in Jul–Sep 2025, 53 flights in Oct–Dec 2025, 33 flights in Jan–Mar 2026 and 24 flights in Apr–Jun 2026. Fewer than three of those quarters carried the 30 completed flights this site needs before printing a rate, so the 75.5% annual figure is the one to use.

Delay causes

Why Republic runs late on this route

One category carries most of the weight here. Carrier accounts for 52% of the 1,762 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
15%
Extreme weather
10%

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 922 of the 1,762 delay minutes reported here. The split is drawn from 1,762 reported delay minutes.

Cancellations run at 2.63%, against 1.81% nationally. That is about one flight in 40 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

For anyone connecting, the number to weigh is not the on-time rate but the tail behind it. 9.1% of arrivals land a full hour or more behind schedule, against 8.1% nationally. A 45-minute layover does not survive that, and no amount of walking quickly changes it. Ninety minutes is the honest minimum here, and two hours if the onward flight is on a separate ticket.

At 248 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 runs 75.5% on time across 114 flights, within half a point 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. 114 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 GSO to DCA

Put together: treat all of this as provisional. 114 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 75.5% headline is the most reliable number on the page; the hour and month splits below it are built on a few dozen flights each. 110 completed flights over 12 months sit behind that.
