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

Republic on JAX to DCA lands a B, about a point better than the national rate of 77.3%. About one flight in five arrives 15 minutes late or worse, and those flights are late by about 2.2 hours on average. That rests on 154 flights, with a median arrival 9 minutes early.

The US average over the same twelve months is 77.3%, so there is little to separate Republic on JAX to DCA from the country as a whole. The variation that matters here is internal: which carrier, and what time of day.

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 33 points, against half a point between the best and worst carrier.

  • 8am–11am48 flights91.5%
  • 11am–2pm37 flights94.4%
  • 2pm–5pm69 flights61.2%
  • 5pm–8pm—
  • 8pm–5am—

Scale runs 55% to 100%. Rows with fewer than 30 flights show a dash.

The best window here is not the first bank but the 11am–2pm slot at 94.4% on time, ahead of 2pm–5pm at 61.2%. Where the curve peaks mid-day rather than at dawn, the constraint is usually congestion at one end rather than the aircraft's own rotation. The 2pm–5pm window is the busiest, with 69 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 78.7% on time across 154 flights.

Split by quarter, Republic on JAX to DCA logged 4 flights in Jul–Sep 2025, 4 flights in Oct–Dec 2025, 42 flights in Jan–Mar 2026, 74 flights in Apr–Jun 2026 and 30 flights in Jul–Sep 2026. Fewer than three of those quarters carried the 30 completed flights this site needs before printing a rate, so the 78.7% annual figure is the one to use.

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 4,252 reported delay minutes.

  • Carrier
    38%
  • National Airspace System
    31%
  • Late-arriving aircraft
    29%
  • Extreme weather
    2%

The largest share of delay minutes, 38%, falls under carrier control: crew scheduling, maintenance, fuelling, baggage. It accounts for 1,597 of the 4,252 delay minutes reported here. The split is drawn from 4,252 reported delay minutes.

Cancellations run at 2.60%, against 1.89% 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

13.3% of arrivals land a full hour or more behind schedule, against 8.3% nationally. Ninety minutes is the honest minimum for a connection here, and two hours if the onward flight is on a separate ticket.

The 634 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 is a different operation and performs like one: it runs 85.2% on time across 154 flights, 7 points above 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. 154 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 JAX to DCA

Put together: treat all of this as provisional. 154 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 78.7% headline is the most reliable number on the page; the hour and month splits below it are built on a few dozen flights each. 150 completed flights over 12 months sit behind that.
