12 of 89 late departures made up the time and arrived on time, 13% of them. In the other direction, 25 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 ORD.
The worst days

The latest arrival of the period was on 6 October 2025, 13 hours 2 minutes behind schedule; most of its delay minutes were filed as carrier-caused (crew, maintenance, fuelling, baggage). On three of the five worst days the largest share was filed as national airspace system delay.

Delay causes
Why DL 2413 runs late
National Airspace System accounts for 49% of the 8,022 delay minutes carriers reported here, and the remaining four split what is left.
- 49%National Airspace System
- 30%Carrier
- 19%Late-arriving aircraft
- 1%Extreme weather
49% 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 3,967 minutes out of 8,022, against a national NAS share of 21%. The split is drawn from 8,022 delay minutes reported on DL 2413.
Cancellations sit at 1.10% against a national 1.89%, which is ordinary. Diversions add another 1.65%.
Connections and routes
What a delay on this flight costs
11.3% 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 1,250 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 363 flights under DL 2413 in the data flew SLC to ORD. 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. 363 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 2413
For a booking, read DL 2413 as 71.1% on time with 1.10% cancelled over 363 flights. Those are rates from the past twelve months, not a forecast for any particular day.
