Share of 271 completed flights by arrival against schedule.
Time lost at the gate mostly stays lost. Of 103 departures that left 15 minutes late or more, only 12 made it up before arrival. In the other direction, 21 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 F9 3424 runs late
National Airspace System accounts for 63% of the 8,658 delay minutes carriers reported here, and the remaining four split what is left.
- 63%National Airspace System
- 20%Late-arriving aircraft
- 13%Carrier
- 4%Extreme weather
63% 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 5,453 minutes out of 8,658, against a national NAS share of 21%. The split is drawn from 8,658 delay minutes reported on F9 3424.
Cancellations run at 6.51%, against 1.89% nationally. That is about one flight in fifteen 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
19.9% 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 1,389 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.
The same number turns up on one other city pair in the data, including CLE to LGA (1), but none flew often enough under F9 3424 to report a rate for. Carriers move flight numbers between routes, so the figures on this page apply to DFW to LGA only.
One caution: this is a thin sample. 292 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 3424
For a booking, the cancellation rate is the figure to plan around on F9 3424: 6.51% of its 292 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.
