Delay causes
Why B6 127 runs late
Late-arriving aircraft accounts for 48% of the 4,875 delay minutes carriers reported here, and the remaining four split what is left.
- 48%Late-arriving aircraft
- 28%National Airspace System
- 22%Carrier
- 2%Extreme weather
48% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. Across 4,875 reported delay minutes here, that single category outweighs weather by 19 to one. The split is drawn from 4,875 delay minutes reported on B6 127.
Cancellations run at 3.46%, against 1.89% nationally. That is about 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
8.8% of arrivals land an hour or more late, close to the national 8.3%, so a 60 to 75 minute layover is reasonable here while anything under 45 minutes is a bet. Most delays on this route last about an hour, which a normal layover absorbs.
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 347 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. 347 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: 3.46% of its 347 scheduled flights did not operate. A late arrival costs about an hour, but a cancellation costs the day, so leave a later option open.
