These figures cover 319 flights between July 2025 and June 2026. Beyond the headline rate, 11.1% 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 1923 flies
B6 1923 flies DCA to MCO without a single fixed slot. Its most common scheduled departure was 11:45, used on 47 of 319 flights, with 12:20 (35 flights) and 11:00 (33 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 11:45 departure sits in the 11am–2pm window. Across every US flight scheduled in that window the on-time rate is 78.8%, and B6 1923 runs 7 points worse at 71.7%. Midday slots inherit some of the morning's delays without yet carrying the full weight of the evening's.

Across the year
B6 1923 quarter by quarter
B6 1923 did not run the same all year. Its best quarter was Apr–Jun 2026 at 82.1% on time and its weakest Jan–Mar 2026 at 62.0%, a swing of 20 points on roughly 80 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.

- Oct–Dec 202586 flights66.7%
- Jan–Mar 202674 flights62.0%

By weekday, B6 1923 did best on Wednesday at 81.8% on time and worst on Sunday at 62.0%. Each day rests on about 46 flights, so a gap of 20 points is worth noticing but could still narrow in another year.
Delay causes
Why B6 1923 runs late
One category carries most of the weight here. Late-arriving aircraft accounts for 52% of the 6,641 delay minutes carriers reported, and the remaining four split what is left. The split is by minutes rather than by flights, so a few very long delays count for as much as many short ones.
- 52%Late-arriving aircraft
- 29%Carrier
- 19%National Airspace System
- 0%Extreme weather
52% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. That is a cascade, and cascades start small and grow through the day. Across 6,641 reported delay minutes here, that single category outweighs weather by 52 to one. It is the strongest argument for booking the first departure of the morning, when the aircraft has been sitting at the gate overnight with nothing to inherit. The split is drawn from 6,641 delay minutes reported on B6 1923.
Cancellations sit at 1.25% against a national 1.81%, which is ordinary. Diversions add another 0.31%.
Connections and routes
What a delay on this flight costs
For anyone connecting, the number to weigh is not the on-time rate but the tail behind it. 11.1% of arrivals land a full hour or more behind schedule, against 8.1% nationally. A 45-minute layover does not survive that, and no amount of walking quickly changes it. Ninety minutes is the honest minimum here, and two hours if the onward flight is on a separate ticket.
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 319 flights under B6 1923 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. 319 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 1923
