Every carrier on IAD to CLT, 1,990 flights
These figures cover 452 flights between September 2025 and August 2026. The median arrival is 12 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 IAD to CLT
Republic flew 452 of the 1,990 flights on IAD to CLT, about 23% of it. Its 81.3% on time is 2 points worse than the route as a whole, which runs 83.1%. Ranked by on-time rate it is last of four carriers on the route, where the range runs from United at 85.7% to Republic at 81.3%. One of those carriers flew fewer than 365 flights here, so treat their positions as rough.
The two carriers here are closely matched: about a point separate the best from the worst. At that spread, schedule and price are better tie-breakers than reliability. Sample sizes are shown so you can see which rows are worth weighing.

|---|---|---|---|---|---|
| United Airlinesthin sample | 35 | 85.7% | 62 min | 0.00% | A+ |

| Republic Airways (this page) | 452 | 81.3% | 67 min | 2.65% | B |
PSA Airlines cancels 3.2% of what it schedules here, the highest in the table. A cancelled flight never appears in an on-time rate, so read that column alongside the punctuality one rather than after it.

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 452 flights.
- 5am–8am—
- 8am–11am118 flights81.4%
- 11am–2pm99 flights83.3%
- 2pm–5pm—
- 5pm–8pm136 flights77.3%
- 8pm–5am99 flights84.7%
Scale runs 70% to 90%. Rows with fewer than 30 flights show a dash.
The 8pm–5am window is the strongest at 84.7% on time. The full set of windows spans 7 points.
Across the year
Republic on IAD to CLT through the year
December is the weak month at 60.8% on time, against 95.7% in September. Winter delays cluster: a single storm system can account for most of a month's shortfall, so an average December hides both very good weeks and genuinely unflyable days. January was the busiest month here, with 74 flights.
Across the week, Wednesday is the strongest day at 91.1% on time and Sunday the weakest at 72.9%, a spread of 18 points.
Arrival by arrival
How late Republic on IAD to CLT runs when it is late
Republic on IAD to CLT often beats the schedule: 187 of 439 completed flights, 43%, arrived 15 minutes or more early. The 82 late arrivals split 24 under half an hour, 33 between 30 and 60 minutes, and 25 an hour or more.

Share of 439 completed flights by arrival against schedule.
Time lost at the gate mostly stays lost. Of 65 departures that left 15 minutes late or more, only 5 made it up before arrival. In the other direction, 22 flights left on time yet arrived 15 minutes late or more, so that delay built up after pushback: in the air, in a holding pattern or on the ground at CLT.
The worst days
Worst days for Republic on IAD to CLT
The latest arrival of the period was on 26 October 2025, 9 hours 8 minutes behind schedule; most of its delay minutes were filed as carrier-caused (crew, maintenance, fuelling, baggage). On three of the five worst days the largest share was filed as a late-arriving aircraft.
| Date | Arrived late by | Largest filed cause |
|---|---|---|
| 26 October 2025 | 9 hours 8 minutes | Carrier |
| 16 March 2026 | 4 hours 23 minutes | Late-arriving aircraft |
| 19 January 2026 | 4 hours 22 minutes | Late-arriving aircraft |
| 26 January 2026 | 3 hours 42 minutes | Late-arriving aircraft |
| 2 March 2026 | 3 hours 29 minutes | Extreme weather |
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 5,518 reported delay minutes.
- 41%Late-arriving aircraft
- 39%Carrier
- 17%National Airspace System
- 3%Extreme weather
41% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. Across 5,518 reported delay minutes here, that single category outweighs weather by 14 to one. The split is drawn from 5,518 reported delay minutes.
The largest share of delay minutes, 39%, falls under carrier control: crew scheduling, maintenance, fuelling, baggage. It accounts for 2,152 of the 5,518 delay minutes reported here.
Cancellations run at 2.65%, 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
5.7% of arrivals land an hour or more late, close to the national 8.3%, so 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 322 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 8pm–5am window matters as much as it does.
The return leg is a different operation and performs like one: it runs 86.6% on time across 454 flights, 5 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 5 points of difference.
One caution: this is a thin sample. 452 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 IAD to CLT
Put together: treat all of this as provisional. 452 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 81.3% headline is the most reliable number on the page; the hour and month splits below it are built on a few dozen flights each. 439 completed flights over 12 months sit behind that.
