These figures cover 353 flights between September 2025 and August 2026. The median arrival is 5 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.

Across the year
B6 2423 quarter by quarter

The twelve-month rate averages over that, so if you are flying in a weak quarter the quarter's own figure is the better guide.

Share of 343 completed flights by arrival against schedule.
10 of 53 late departures made up the time and arrived on time, 19% of them. In the other direction, 28 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 MCO.

Delay causes
Why B6 2423 runs late
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 4,495 reported delay minutes.
- 40%Carrier
- 33%National Airspace System
- 26%Late-arriving aircraft
- 0%Extreme weather
The largest share of delay minutes, 40%, falls under carrier control: crew scheduling, maintenance, fuelling, baggage. It accounts for 1,818 of the 4,495 delay minutes reported here. The split is drawn from 4,495 delay minutes reported on B6 2423.
Cancellations run at 2.83%, against 1.89% nationally. That is roughly 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 routes
What a delay on this flight costs
7.6% 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.
The 759 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.
Every one of the 353 flights under B6 2423 in the data flew DCA to MCO. The number was not reused on any other city pair, which makes this a clean record of one route.
One caution: this is a thin sample. 353 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 B6 2423
For a booking, the cancellation rate is the figure to plan around on B6 2423: 2.83% of its 353 scheduled flights did not operate. A late arrival costs about an hour, but a cancellation costs the day, so leave a later option open.
