These figures cover 364 flights between September 2025 and August 2026. The median arrival is 7 minutes early, which is the part an average hides: most flights here are fine, and the on-time rate is decided by a tail of badly late ones. On-time means under 15 minutes late, the DOT's own threshold.

Across the year
DL 1038 quarter by quarter
DL 1038 did not run the same all year. Its best quarter was Oct–Dec 2025 at 86.8% on time and its weakest Jan–Mar 2026 at 74.2%, a swing of 13 points on roughly 73 flights a 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.

Share of 360 completed flights by arrival against schedule.
12 of 58 late departures made up the time and arrived on time, 21% of them. In the other direction, 23 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 FLL.
The worst days
Worst days for DL 1038
The latest arrival of the period was on 16 March 2026, 9 hours 16 minutes behind schedule; most of its delay minutes were filed as extreme weather. The five worst days are spread across March, January, July and August, with no single month standing out.
| Date | Arrived late by | Largest filed cause |
|---|---|---|
| 16 March 2026 | 9 hours 16 minutes | Extreme weather |
| 7 March 2026 | 6 hours 5 minutes | National Airspace System |

Delay causes
Why DL 1038 runs late
Carriers report a reason for every delay minute they cause, in five DOT categories. The split below is by minutes, not by number of flights, so a handful of very long weather delays weighs as much as many short ones. It covers 4,630 reported delay minutes.
- 37%National Airspace System
- 30%Carrier
- 26%Late-arriving aircraft
- 8%Extreme weather
37% 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 1,706 minutes out of 4,630, against a national NAS share of 21%. The split is drawn from 4,630 delay minutes reported on DL 1038.
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
6.1% of arrivals land an hour or more late, close to the national 8.3%, so a 60 to 75 minute layover is reasonable here while anything under 45 minutes is a bet. Most delays on this route last about an hour, which a normal layover absorbs.
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 1038 in the data flew RDU to FLL. 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 1038
