Better than 23% of comparable major US routes (4,598 compared)
Calculated from 20,170 flights. How this is calculated
DCA → ORD arrives on time 79.0% of the time; the return trip, ORD → DCA, arrives on time 73.0% of the time, a 6.0-point gap between the two directions of the same city pair.
DCA → ORD spends 35.7 minutes on the ground on a 612-mile trip: 19.1 minutes from pushback to wheels-up at DCA and 16.6 minutes from touchdown to gate at ORD.

Why DCA → ORD flights are cancelled
July 2023 – July 2026
DCA → ORD cancelled 499 of 20,170 scheduled flights — about 1 in every 40. The reason filed most often was extreme weather, 69.7% of the cancellations coded on this route — about 1 in every 58 scheduled flights.
Share of cancellations
Of 499 cancelled departures carrying a reason code.
What each reason means
Conditions the carrier judged severe enough to stop the flight: a blizzard, a hurricane, a line of thunderstorms.
348 cancellations, 69.7% of the total.
Crew, maintenance, aircraft cleaning, baggage or fueling: what BTS counts as within the carrier’s own control.
93 cancellations, 18.6% of the total.
Airport capacity, air traffic control flow programs, heavy traffic and ordinary bad weather. A system decision, not the airline’s.
58 cancellations, 11.6% of the total.
A terminal evacuation, a security breach, screening equipment failure, or screening queues over 29 minutes.
0 cancellations, 0.0% of the total.
Reason codes are the operating airline’s own filing with US DOT, not an independent finding of fault. Ordinary bad weather is filed under air traffic, so weather’s full share is larger than its bar.
499 coded cancellations were recorded on DCA → ORD; the section appears from 50.

Will your connection be tight enough?
Layovers at ORD after arriving from DCA.
| Connection time | Chance of missing | Reads as |
|---|---|---|
| 30 min | 34% | Likely to miss |
| 45 min | 20% | High risk |
| 60 min | 14% | Some risk |
| 90 min | 8.9% | Some risk |
| 120 min | 6.1% | Some risk |
This is one leg of a connection. Gate changes and the next flight's own schedule matter too. And a connection can fail before delay is even the question — this route cancels 2.47% of the time and diverts 0.21% of the time, which a late arrival never shows up in.
Chance of missing is the share of 19,629 arrivals on this route that landed later than the connection time less 30 minutes to reach the next gate.
The worst tenth of arrivals on this route land at least 51 minutes late (90th-percentile gate arrival delay), over 20,170 operations.

Best time to fly
DCA → ORD flights departing 5–9 AM arrived on time 90.2% of the time, against 65.7% for 6–9 PM departures, a gap of 24.5 percentage points.
By day and hour
On-time arrival rate for each weekday and scheduled departure hour, in local time at the departure airport (DCA).
Hour of departure matters more than day of the week: hourly averages sit a typical 10.9 points from the route-wide rate, weekday averages 2.3 points.

Why DCA → ORD runs late
July 2023 – July 2026
the inbound aircraft was late, so this flight started late
airspace and airport capacity, including weather-driven flow control
crew, maintenance, boarding and fueling, all within the carrier’s control
weather severe enough to stop this flight specifically
screening or terminal security incidents
Share of the delay minutes US DOT attributed to each cause for DCA → ORD. Only delays of 15 minutes or more are attributed.
Late-arriving aircraft is the largest cause on DCA → ORD, at 42.4%: flights here mostly leave late because the plane came in late, and the day shows it: 5–9 AM departures arrived on time 90.2% of the time and 6–9 PM departures 65.7%.
