This route carries a cancellation problem, not just a delay problem: 5.6% of scheduled flights never operate, against 1.9% nationally. Of the ones that do fly, about seven flights in ten arrive on time, worth a C− overall. The punctuality figure counts only flights that actually departed, so it flatters an operation that cancels this often. That rests on 1,093 CAE to DCA flights, with a median arrival 9 minutes early.
Best time to fly CAE to DCA: a 5am–8am departure, ideally on a Saturday. Flights in that window arrived on time 88.8% of the time and Saturday flights 77.7%, against 72.6% for the route overall.
The national on-time rate over the same period is 77.3%, so this route runs 5 points behind the country as a whole. Across a thousand flights that is about 47 extra late arrivals.

The 5pm–8pm window is where this operation falls apart: 48.2% on time, against 88.8% for the 5am–8am slot. By evening the aircraft flying these rotations have absorbed a full day of small delays and there is no slack left to recover in. The 5am–8am window is the busiest, with 350 flights scheduled in it.

Across the year
When delays peak on this route
This route's year swings by 26 points from best month to worst, which is wide. An annual average tells you very little about the week you are actually flying, so read the strip rather than the headline if your dates are fixed.
February is the weak month at 56.8% on time, against 83.0% 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. October was the busiest month here, with 116 flights.
Across the week, Saturday is the strongest day at 77.7% on time and Friday the weakest at 64.5%, a spread of 13 points.
Delay causes
Why this route gets delayed
Late-arriving aircraft accounts for 47% of the 30,000 delay minutes carriers reported here, and the remaining four split what is left.
- 47%Late-arriving aircraft
- 33%Carrier
- 12%National Airspace System
- 8%Extreme weather
- 0%Security
47% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. Across 30,000 reported delay minutes here, that single category outweighs weather by 6 to one. The split is drawn from 30,154 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 88.8% on time here.
Cancellations run at 5.58%, against 1.89% nationally. That is roughly one flight in twenty 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 actually costs
11.4% 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.
At 408 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 66.7% on time across 1,092 flights, 6 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 6 points of difference.
One caution: this is a thin sample. 1,093 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 this route
Put together: the delay figures matter less here than the 5.58% cancellation rate. A late arrival costs you close to two hours; 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. 1,026 completed flights over 12 months sit behind that.
Common questions
CAE to DCA questions
How often is CAE to DCA delayed?
Roughly one flight in four arrives at least 15 minutes late, which is the Department of Transportation's definition of a delayed arrival. That works out to 27.4% of the 1,093 flights in this analysis, against 22.7% nationally. Delayed flights are late by close to two hours on average.
How reliable is CAE to DCA compared with the rest of the country?
72.6% of flights arrive on time here against a national 77.3%, a difference of 5 points against it. That is worth a C− on this site's grading scale.
What time of day has the fewest delays on CAE to DCA?
The 5am–8am departure window is the strongest at 88.8% on time. The 5pm–8pm window is the weakest at 48.2%, 41 points behind. Later departures inherit delays from earlier flights the same aircraft has already flown, which is why the curve slopes the way it does.
How bad are February delays on CAE to DCA?
February is the weakest month at 56.8% on time, compared with 83.0% in September. Across the year that is 26 points between the best and worst months. Moving flexible dates out of that month is one of the few things that reliably helps.
