Share of 344 completed flights by arrival against schedule.
Time lost at the gate mostly stays lost. Of 65 departures that left 15 minutes late or more, only 4 made it up before arrival. In the other direction, 27 flights left on time yet arrived 15 minutes late or more, so that delay built up after pushback: in the air, in a holding pattern or on the ground at LGA.

Delay causes
Why B6 598 runs late
National Airspace System accounts for 46% of the 6,070 delay minutes carriers reported here, and the remaining four split what is left.

- 32%Late-arriving aircraft
- 17%Carrier
- 6%Extreme weather
- 0%Security
46% 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 2,772 minutes out of 6,070, against a national NAS share of 21%. The split is drawn from 6,070 delay minutes reported on B6 598.
Cancellations run at 4.96%, against 1.89% nationally. That is about one flight in twenty 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
9.3% 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 950 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 363 flights under B6 598 in the data flew MCO to LGA. 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. 363 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 598
For a booking, the cancellation rate is the figure to plan around on B6 598: 4.96% of its 363 scheduled flights did not operate. A late arrival costs a little over an hour, but a cancellation costs the day, so leave a later option open.
