Delay causes
Why YX 5671 runs late
Carriers report a reason for every delay minute they cause, in five DOT categories. The split below is by minutes, not by number of flights, so a handful of very long weather delays weighs as much as many short ones. It covers 7,745 reported delay minutes.
- 35%Carrier
- 32%National Airspace System
- 31%Late-arriving aircraft
- 2%Extreme weather
The largest share of delay minutes, 35%, falls under carrier control: crew scheduling, maintenance, fuelling, baggage. It accounts for 2,681 of the 7,745 delay minutes reported here. The split is drawn from 7,745 delay minutes reported on YX 5671.
Cancellations run at 5.06%, 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
14.7% 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 same number turns up on one other city pair in the data, including DTW to MEM (11), but none flew often enough under YX 5671 to report a rate for. Carriers move flight numbers between routes, so the figures on this page apply to LGA to CMH only.
One caution: this is a thin sample. 316 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 YX 5671
For a booking, the cancellation rate is the figure to plan around on YX 5671: 5.06% of its 316 scheduled flights did not operate. A late arrival costs an hour and a half, but a cancellation costs the day, so leave a later option open.
