Across the year
DL 1018 quarter by quarter

The latest arrival of the period was on 2 January 2026, 14 hours 52 minutes behind schedule; most of its delay minutes were filed as carrier-caused (crew, maintenance, fuelling, baggage). The same cause led on three of the five worst days.
| Date | Arrived late by | Largest filed cause |
|---|---|---|
| 2 January 2026 | 14 hours 52 minutes | Carrier |
| 16 March 2026 | 9 hours 33 minutes | Late-arriving aircraft |
| 29 November 2025 | 7 hours 44 minutes | Carrier |
| 7 March 2026 | 6 hours 5 minutes | Late-arriving aircraft |

Delay causes
Why DL 1018 runs late
Late-arriving aircraft accounts for 51% of the 8,248 delay minutes carriers reported here, and the remaining four split what is left.
- 51%Late-arriving aircraft
- 33%Carrier
- 13%National Airspace System
- 4%Extreme weather
51% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. Across 8,248 reported delay minutes here, that single category outweighs weather by 13 to one. The split is drawn from 8,248 delay minutes reported on DL 1018.
Cancellations are rare at 0.55%, below the national 1.89% and low enough to earn the plus on the grade. Roughly one flight in 100 is called off; the risk here is arriving late, not not arriving.
Connections and routes
What a delay on this flight costs
10.0% 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 680 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 364 flights under DL 1018 in the data flew FLL to RDU. 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. 364 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 1018
For a booking, read DL 1018 as 75.0% on time with 0.55% cancelled over 364 flights. Those are rates from the past twelve months, not a forecast for any particular day.
