These figures cover 356 flights between July 2025 and June 2026. Beyond the headline rate, 17.5% 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 128 flies
B6 128 flies MCO to EWR without a single fixed slot. Its most common scheduled departure was 13:30, used on 51 of 356 flights, with 14:45 (43 flights) and 14:15 (40 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 13:30 departure sits in the 11am–2pm window. Across every US flight scheduled in that window the on-time rate is 78.8%, and B6 128 runs 10 points worse at 68.7%. Midday slots inherit some of the morning's delays without yet carrying the full weight of the evening's.

Across the year
B6 128 quarter by quarter
B6 128 did not run the same all year. Its best quarter was Apr–Jun 2026 at 83.1% on time and its weakest Oct–Dec 2025 at 61.2%, 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 128 ranged from 63.6% on Wednesday to 73.5% on Monday. With about 51 flights behind each day, a spread of 10 points is inside normal variation, so the day you fly is not worth changing for this flight.
Delay causes
Why B6 128 runs late
One category carries most of the weight here. National Airspace System accounts for 55% of the 12,000 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.
- 55%National Airspace System
- 25%Late-arriving aircraft
- 18%Carrier
- 2%Extreme weather
55% 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 6,321 minutes out of 12,000, against a national NAS share of 21%. The split is drawn from 11,518 delay minutes reported on B6 128.
Cancellations run at 6.18%, against 1.81% nationally. That is about one flight in fifteen 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
For anyone connecting, the number to weigh is not the on-time rate but the tail behind it. 17.5% 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 937 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 356 flights under B6 128 in the data flew MCO to EWR. 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. 356 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 128
For a booking, the cancellation rate is the figure to plan around on B6 128: 6.18% of its 356 scheduled flights did not operate. A late arrival costs close to two hours, but a cancellation costs the day, so leave a later option open.
