Across the year
DL 1312 quarter by quarter

The twelve-month rate averages over that, so if you are flying in a weak quarter the quarter's own figure is the better guide.

The five worst days are spread across February, July, May, March and August, with no single month standing out.
| Date | Arrived late by | Largest filed cause |
|---|---|---|
| 16 February 2026 | 19 hours 12 minutes | Carrier |
| 26 July 2026 | 7 hours 21 minutes | Carrier |
| 2 May 2026 | 6 hours 12 minutes | Late-arriving aircraft |

Delay causes
Why DL 1312 runs late
Late-arriving aircraft accounts for 46% of the 6,334 delay minutes carriers reported here, and the remaining four split what is left.
- 46%Late-arriving aircraft
- 38%Carrier
- 10%National Airspace System
- 7%Extreme weather
46% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. Across 6,334 reported delay minutes here, that single category outweighs weather by 7 to one. The split is drawn from 6,334 delay minutes reported on DL 1312.
Cancellations sit at 1.72% against a national 1.89%, which is ordinary. Diversions add another 0.00%.
Connections and routes
What a delay on this flight costs
10.2% 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 534 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 three other city pairs in the data, including ATL to SAT (73), SAT to ATL (72) and RDU to MCO (62), but none flew often enough under DL 1312 to report a rate for. Carriers move flight numbers between routes, so the figures on this page apply to MCO to RDU only.
One caution: this is a thin sample. 290 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 1312
For a booking, read DL 1312 as 75.1% on time with 1.72% cancelled over 290 flights. Those are rates from the past twelve months, not a forecast for any particular day.
