B6 2423 lands a B, about a point better than the national rate of 77.6%. About one flight in five arrives 15 minutes late or worse, and those flights are late by a little over an hour on average.

These figures cover 357 flights between July 2025 and June 2026. Beyond the headline rate, 8.0% of arrivals land a full hour or more behind schedule. That is the number that wrecks a connection, and it is not visible in an on-time percentage alone.

Schedule

When B6 2423 flies

B6 2423 flies DCA to MCO without a single fixed slot. Its most common scheduled departure was 09:00, used on 70 of 357 flights, with 08:55 (43 flights) next. Carriers retime flights through the season, so the rates here blend slightly different positions in the aircraft's day.

Share of scheduled departures at each local time. Times used on fewer than one flight in ten are not listed.

A 09:00 departure sits in the 8am–11am window. Across every US flight scheduled in that window the on-time rate is 84.1%, and B6 2423 runs 5 points worse at 78.8%. Early departures usually start with an aircraft that has not flown yet that day, which is most of why the window does well.

Across the year

B6 2423 quarter by quarter

B6 2423 did not run the same all year. Its best quarter was Apr–Jun 2026 at 90.5% on time and its weakest Oct–Dec 2025 at 68.9%, a swing of 22 points on roughly 89 flights a 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.

By weekday, B6 2423 did best on Wednesday at 88.5% on time and worst on Sunday at 70.6%. Each day rests on about 51 flights, so a gap of 18 points is worth noticing but could still narrow in another year.

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 5,060 reported delay minutes.

National Airspace System
39%
Carrier
33%
Late-arriving aircraft
28%
Extreme weather
0%
Security
0%

39% of delay minutes are charged to the National Airspace System: air traffic volume, runway configuration, ground stops. No carrier can price its way out of that, which is why airport choice moves the number here more than carrier choice does. That is 1,985 minutes out of 5,060, against a national NAS share of 21%. The split is drawn from 5,060 delay minutes reported on B6 2423.

Cancellations sit at 1.96% against a national 1.81%, which is ordinary. Diversions add another 0.28%.

Connections and routes

What a delay on this flight costs

8.0% of arrivals land an hour or more late, close to the national 8.1%. That is the figure that decides a connection, and it says 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.

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. It is also long enough that the aircraft usually flies three or four legs a day rather than six, which slows how fast delay compounds.

Every one of the 357 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. 357 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.
