Delay causes
Why DL 2576 runs late
National Airspace System accounts for 42% of the 7,563 delay minutes carriers reported here, and the remaining four split what is left.
- 42%National Airspace System
- 31%Carrier
- 25%Late-arriving aircraft
- 2%Extreme weather
42% 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 3,191 minutes out of 7,563, against a national NAS share of 21%. The split is drawn from 7,563 delay minutes reported on DL 2576.
Cancellations sit at 0.90% against a national 1.89%, which is ordinary. Diversions add another 0.90%.
Connections and routes
What a delay on this flight costs
12.0% 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 919 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 MIA to DCA (69), but none flew often enough under DL 2576 to report a rate for. Carriers move flight numbers between routes, so the figures on this page apply to DCA to MIA only.
One caution: this is a thin sample. 332 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 2576
For a booking, DL 2576 is a flight to put a long connection behind. 12.0% of its completed flights arrived an hour or more late, which a short layover will not absorb. If the onward flight is on a separate ticket, the risk sits with you.
