Across the year
DL 2345 quarter by quarter

Share of 349 completed flights by arrival against schedule.
Time lost at the gate mostly stays lost. Of 102 departures that left 15 minutes late or more, only 11 made it up before arrival. In the other direction, 28 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 2345
The latest arrival of the period was on 24 July 2026, 5 hours 34 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 |

| 24 July 2026 | 5 hours 34 minutes | Carrier |
| 16 March 2026 | 5 hours 4 minutes | Carrier |

Delay causes
Why DL 2345 runs late
Carrier accounts for 51% of the 7,290 delay minutes carriers reported here, and the remaining four split what is left.
- 51%Carrier
- 25%National Airspace System
- 19%Late-arriving aircraft
- 4%Extreme weather
- 1%Security
The largest share of delay minutes, 51%, falls under carrier control: crew scheduling, maintenance, fuelling, baggage. It accounts for 3,726 of the 7,290 delay minutes reported here. The split is drawn from 7,290 delay minutes reported on DL 2345.
Cancellations are rare at 0.57%, 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
12.6% 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 581 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.
DL 2345 is not only a ATL to FLL flight. It also flew FLL to ATL (345 flights, 65.9% on time) often enough to be scored on its own. Airlines attach one number to several legs of an aircraft's day, and each leg keeps its own record here, so check which city pair is on your booking before reading a rate.
One caution: this is a thin sample. 351 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 2345
For a booking, DL 2345 is a flight to put a long connection behind. 12.6% of its completed flights arrived an hour or more late, which a short layover will not absorb. If the onward flight is on a separate ticket, the risk sits with you.
