These figures cover 348 flights between July 2025 and June 2026. Beyond the headline rate, 10.5% 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 127 flies

B6 127 flies EWR to MCO without a single fixed slot. Its most common scheduled departure was 09:45, used on 59 of 348 flights, with 11:00 (53 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 09:45 departure sits in the 8am–11am window. Across every US flight scheduled in that window the on-time rate is 84.1%, and B6 127 runs 10 points worse at 74.0%. 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 127 quarter by quarter

B6 127 did not run the same all year. Its best quarter was Apr–Jun 2026 at 82.4% on time and its weakest Oct–Dec 2025 at 55.4%, a swing of 27 points on roughly 87 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 127 did best on Wednesday at 87.2% on time and worst on Sunday at 58.7%. Each day rests on about 50 flights, so a gap of 29 points is worth noticing but could still narrow in another year.

Delay causes

Why B6 127 runs late

One category carries most of the weight here. Late-arriving aircraft accounts for 52% of the 5,868 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% 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 5,868 reported delay minutes here, that single category outweighs weather by 40 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 5,868 delay minutes reported on B6 127.

Cancellations run at 2.87%, against 1.81% nationally. That is roughly one flight in 30 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. 10.5% 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 348 flights under B6 127 in the data flew EWR 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. 348 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 127

For a booking, the cancellation rate is the figure to plan around on B6 127: 2.87% of its 348 scheduled flights did not operate. A late arrival costs about an hour, but a cancellation costs the day, so leave a later option open.
