Across the year
DL 1370 quarter by quarter
DL 1370 did not run the same all year. Its best quarter was Apr–Jun 2026 at 81.3% on time and its weakest Jul–Sep 2026 at 52.2%, a swing of 29 points on roughly 71 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.

By weekday, DL 1370 did best on Wednesday at 83.3% on time and worst on Sunday at 53.5%. Each day rests on about 41 flights, so a gap of 30 points is worth noticing but could still narrow in another year.
Arrival by arrival
How late DL 1370 runs when it is late
DL 1370 often beats the schedule: 100 of 276 completed flights, 36%, arrived 15 minutes or more early. The 80 late arrivals split 20 under half an hour, 22 between 30 and 60 minutes, and 38 an hour or more.

Share of 276 completed flights by arrival against schedule.
12 of 76 late departures made up the time and arrived on time, 16% of them. In the other direction, 16 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 RDU.
The worst days
Worst days for DL 1370
The latest arrival of the period was on 8 December 2025, 12 hours 52 minutes behind schedule; most of its delay minutes were filed as carrier-caused (crew, maintenance, fuelling, baggage). On four of the five worst days the largest share was filed as a late-arriving aircraft.
| Date | Arrived late by | Largest filed cause |
|---|---|---|
| 8 December 2025 | 12 hours 52 minutes | Carrier |
| 7 December 2025 | 4 hours 9 minutes | Late-arriving aircraft |
| 26 July 2026 | 4 hours 2 minutes | Late-arriving aircraft |
| 16 February 2026 | 3 hours 36 minutes | Late-arriving aircraft |
| 15 February 2026 | 3 hours 33 minutes | Late-arriving aircraft |
Delay causes
Why DL 1370 runs late
Late-arriving aircraft accounts for 74% of the 6,454 delay minutes carriers reported here, and the remaining four split what is left.
- 74%Late-arriving aircraft
- 13%Carrier
- 11%National Airspace System
- 2%Extreme weather
74% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. Across 6,454 reported delay minutes here, that single category outweighs weather by 36 to one. The split is drawn from 6,454 delay minutes reported on DL 1370.
Cancellations run at 3.16%, against 1.89% nationally. That is about one flight in 30 cancelled outright. A cancelled flight is invisible in every on-time figure on this page, so the punctuality numbers above describe only the flights that actually operated.
Connections and routes
What a delay on this flight costs
13.8% 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.
Every one of the 285 flights under DL 1370 in the data flew MCO 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. 285 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 1370
For a booking, the cancellation rate is the figure to plan around on DL 1370: 3.16% of its 285 scheduled flights did not operate. A late arrival costs a little over an hour, but a cancellation costs the day, so leave a later option open.
