These figures cover 341 flights between September 2025 and August 2026. The median arrival is 8 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 07:30 departure sits in the 5am–8am window. Across every US flight scheduled in that window the on-time rate is 89.3%, and DL 2474 runs level with that at 87.6%. Early departures usually start with an aircraft that has not flown yet that day, which is most of why the window does well.

Across the year
DL 2474 quarter by quarter
DL 2474 did not run the same all year. Its best quarter was Jul–Sep 2026 at 96.8% on time and its weakest Jan–Mar 2026 at 78.5%, a swing of 18 points on roughly 85 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 2474 did best on Friday at 93.8% on time and worst on Thursday at 79.2%. Each day rests on about 49 flights, so a gap of 15 points is worth noticing but could still narrow in another year.
Arrival by arrival
How late DL 2474 runs when it is late
DL 2474 often beats the schedule: 109 of 339 completed flights, 32%, arrived 15 minutes or more early. The 42 late arrivals split 14 under half an hour, 16 between 30 and 60 minutes, and 12 an hour or more.

Share of 339 completed flights by arrival against schedule.
7 of 28 late departures made up the time and arrived on time, 25% of them. In the other direction, 21 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 RSW.
The worst days
Worst days for DL 2474
The latest arrival of the period was on 20 November 2025, 12 hours 33 minutes behind schedule; most of its delay minutes were filed as carrier-caused (crew, maintenance, fuelling, baggage). The same cause led on five of the five worst days.
| Date | Arrived late by | Largest filed cause |
|---|---|---|
| 20 November 2025 | 12 hours 33 minutes | Carrier |
| 18 January 2026 | 4 hours 35 minutes | Carrier |
| 18 September 2025 | 4 hours 16 minutes | Carrier |
| 22 July 2026 | 3 hours 24 minutes | Carrier |

Delay causes
Why DL 2474 runs late
Carrier accounts for 75% of the 3,255 delay minutes carriers reported here, and the remaining four split what is left.
- 75%Carrier
- 23%National Airspace System
- 1%Late-arriving aircraft
- 0%Extreme weather
The largest share of delay minutes, 75%, falls under carrier control: crew scheduling, maintenance, fuelling, baggage. It accounts for 2,445 of the 3,255 delay minutes reported here. The split is drawn from 3,255 delay minutes reported on DL 2474.
Cancellations are rare at 0.59%, 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
Badly late arrivals are rare here: only 3.5% 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 1,249 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 RSW to BOS (76), but none flew often enough under DL 2474 to report a rate for. Carriers move flight numbers between routes, so the figures on this page apply to BOS to RSW only.
One caution: this is a thin sample. 341 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 2474
For a booking, DL 2474 has one of the better records a US domestic flight can show: 87.6% on time and 0.59% cancelled. That is a base rate, not a promise about any single day.
