Delay causes
Why B6 128 runs late
National Airspace System accounts for 58% of the 11,000 delay minutes carriers reported here, and the remaining four split what is left.
- 58%National Airspace System
- 28%Late-arriving aircraft
- 12%Carrier
- 1%Extreme weather
58% 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 11,000, against a national NAS share of 21%. The split is drawn from 10,871 delay minutes reported on B6 128.
Cancellations run at 7.58%, against 1.89% nationally. That is roughly one flight in twelve 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
18.1% of arrivals land a full hour or more behind schedule, against 8.3% nationally. Ninety minutes is the honest minimum for a connection 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.
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: 7.58% 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.
