Every carrier on DCA to JAX, 1,435 flights

These figures cover 154 flights between September 2025 and August 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 DCA to JAX

Republic flew 154 of the 1,435 flights on DCA to JAX, about 11% of it. Its 85.2% on time is 12 points better than the route as a whole, which runs 73.0%. Ranked by on-time rate it is first of three carriers on the route, where the range runs from Republic at 85.2% to PSA at 68.3%. 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 matters more here than the choice of carrier. The gap between the best and worst window is 20 points, against half a point between the best and worst carrier.

8am–11am38 flights94.4%

Scale runs 65% 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 74.2% on time against 94.4% for 8am–11am. 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 11am–2pm window is the busiest, with 68 flights scheduled in it.

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 1,161 reported delay minutes.

Carrier
34%
Late-arriving aircraft
30%
National Airspace System
23%
Extreme weather
13%

Extreme weather accounts for 13% 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 2.1 times the usual weather exposure. The split is drawn from 1,161 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 94.4% on time here.

Cancellations sit at 1.95% against a national 1.89%, which is ordinary. Diversions add another 1.30%.

Connections and stage length

What a delay here costs

Badly late arrivals are rare here: only 3.4% land an hour or more behind schedule, against 8.3% 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.

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 78.7% on time across 154 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. 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 DCA to JAX

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 85.2% headline is the most reliable number on the page; the hour and month splits below it are built on a few dozen flights each. 149 completed flights over 12 months sit behind that.
