These figures cover 454 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 CLT to IAD
Republic flew 454 of the 1,992 flights on CLT to IAD, about 23% of it. Its 86.6% on time is 7 points better than the route as a whole, which runs 79.5%. Ranked by on-time rate it is number two of four carriers on the route, where the range runs from United at 97.1% to American at 68.7%. One of those carriers flew fewer than 365 flights here, so treat their positions as rough.
The choice of carrier is not cosmetic here. PSA Airlines arrives on time 81.5% of the time; American Airlines manages 68.7%. Sample sizes sit next to every figure, because a two-point gap across 537 flights means less than a ten-point one.

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 matters more here than the choice of carrier. The gap between the best and worst window is 12 points, against 13 points between the best and worst carrier.

- 8am–11am171 flights88.5%
- 11am–2pm—

Scale runs 75% to 100%. Rows with fewer than 30 flights show a dash.
Book the early departure. Flights leaving between 5am–8am arrive on time 93.8% of the time, against 82.3% for the afternoon window. That is 12 points of difference for no extra money, and it comes from the same aircraft having had no earlier flight to fall behind on. The 8am–11am window is the busiest, with 171 flights scheduled in it.

The worst days
Worst days for Republic on CLT to IAD
The latest arrival of the period was on 14 December 2025, 4 hours 13 minutes behind schedule; most of its delay minutes were filed as a late-arriving aircraft. The same cause led on five of the five worst days.
| Date | Arrived late by | Largest filed cause |
|---|---|---|
| 14 December 2025 | 4 hours 13 minutes | Late-arriving aircraft |
| 7 March 2026 | 3 hours 44 minutes | Late-arriving aircraft |
| 19 January 2026 | 3 hours 38 minutes | Late-arriving aircraft |
| 26 January 2026 | 3 hours 22 minutes | Late-arriving aircraft |

Delay causes
Why Republic runs late on this route
Late-arriving aircraft accounts for 61% of the 4,667 delay minutes carriers reported here, and the remaining four split what is left.
- 61%Late-arriving aircraft
- 22%National Airspace System
- 16%Carrier
- 1%Extreme weather
61% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. Across 4,667 reported delay minutes here, that single category outweighs weather by 55 to one. The split is drawn from 4,667 reported delay minutes.
The practical consequence: the 5am–8am departure is the one that starts clean. Its aircraft has no earlier leg to be late from, which is exactly why that window shows 93.8% on time here.
Cancellations run at 2.86%, against 1.89% nationally. That is roughly one flight in 30 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
7.0% 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 a little over 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 5am–8am window matters as much as it does.
The return leg is a different operation and performs like one: it runs 81.3% on time across 452 flights, 5 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 5 points of difference.
One caution: this is a thin sample. 454 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 CLT to IAD
Put together: the delay figures matter less here than the 2.86% cancellation rate. A late arrival costs you a little over an hour; a cancelled flight costs you the day. Book the 5am–8am departure so there is still a schedule behind you if it goes wrong, and treat a same-day connection as optimistic. 441 completed flights over 12 months sit behind that.
