These figures cover 365 flights between September 2025 and August 2026. The median arrival is 13 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.

Share of scheduled departures at each local time. Times used on fewer than one flight in ten are not listed.
A 07:05 departure sits in the 5am–8am window. Across every US flight scheduled in that window the on-time rate is 89.3%, and DL 2347 runs level with that at 88.4%. Early departures usually start with an aircraft that has not flown yet that day, which is most of why the window does well.

Arrival by arrival
How late DL 2347 runs when it is late
DL 2347 often beats the schedule: 155 of 345 completed flights, 45%, arrived 15 minutes or more early. The 40 late arrivals split 18 under half an hour, 16 between 30 and 60 minutes, and 6 an hour or more.

Share of 345 completed flights by arrival against schedule.
A late pushback is often recovered here: of 26 departures that left 15 minutes late or more, 9 still arrived on time. 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 MIA.
The worst days
Worst days for DL 2347
The latest arrival of the period was on 17 February 2026, 2 hours 10 minutes behind schedule; most of its delay minutes were filed as carrier-caused (crew, maintenance, fuelling, baggage). The same cause led on four of the five worst days.
| Date | Arrived late by | Largest filed cause |
|---|---|---|
| 17 February 2026 | 2 hours 10 minutes | Carrier |
| 7 September 2025 | 1 hour 38 minutes | Carrier |
| 15 April 2026 | 1 hour 33 minutes | Carrier |
| 23 August 2026 | 1 hour 28 minutes | National Airspace System |

Delay causes
Why DL 2347 runs late
National Airspace System accounts for 49% of the 1,565 delay minutes carriers reported here, and the remaining four split what is left.

- 3%Extreme weather
The largest share of delay minutes, 48%, falls under carrier control: crew scheduling, maintenance, fuelling, baggage. It accounts for 750 of the 1,565 delay minutes reported here. The split is drawn from 1,565 delay minutes reported on DL 2347.
Cancellations run at 5.21%, against 1.89% nationally. That is about one flight in twenty 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
Badly late arrivals are rare here: only 1.7% land an hour or more behind schedule, against 8.3% nationally. Connections built on this flight are about as safe as US domestic connections get, though a cancelled flight still ignores every layover you give it.
The 1,096 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 one other city pair in the data, including MIA to LGA (132), but none flew often enough under DL 2347 to report a rate for. Carriers move flight numbers between routes, so the figures on this page apply to LGA to MIA only.
One caution: this is a thin sample. 365 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 2347
For a booking, the cancellation rate is the figure to plan around on DL 2347: 5.21% of its 365 scheduled flights did not operate. A late arrival costs about 40 minutes, but a cancellation costs the day, so leave a later option open.
