Delay causes
Why F9 3453 runs late
Late-arriving aircraft accounts for 72% of the 14,000 delay minutes carriers reported here, and the remaining four split what is left.
- 72%Late-arriving aircraft
- 16%Carrier
- 12%National Airspace System
72% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. Across 14,000 reported delay minutes here, that single category outweighs weather by 72 to one. The split is drawn from 14,155 delay minutes reported on F9 3453.
Cancellations run at 9.77%, against 1.89% nationally. That is about one flight in ten 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
28.5% 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 762 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 266 flights under F9 3453 in the data flew LGA to ATL. 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. 266 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 F9 3453
For a booking, the cancellation rate is the figure to plan around on F9 3453: 9.77% of its 266 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.
