Delay causes
Why DL 2661 runs late
National Airspace System accounts for 51% of the 4,887 delay minutes carriers reported here, and the remaining four split what is left.
- 51%National Airspace System
- 41%Carrier
- 7%Late-arriving aircraft
- 1%Extreme weather
The largest share of delay minutes, 41%, falls under carrier control: crew scheduling, maintenance, fuelling, baggage. It accounts for 1,995 of the 4,887 delay minutes reported here. The split is drawn from 4,887 delay minutes reported on DL 2661.
Cancellations run at 3.03%, against 1.89% nationally. That is roughly 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
10.3% 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 1,029 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 264 flights under DL 2661 in the data flew MSP to JFK. 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. 264 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 DL 2661
For a booking, the cancellation rate is the figure to plan around on DL 2661: 3.03% of its 264 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.
