Historical statistics for July 2025 to June 2026, not live status. For today’s DL 2474, check with Delta Air Lines.

DL 2474 earns an A+. More than four flights in five arrive inside the 15-minute window the DOT uses to define an on-time arrival, which puts it 9 points better than the national rate of 77.6%. When something does go wrong the average delay runs a little over an hour. That rests on 341 flights, with a median arrival 8 minutes early.

Set against the rest of the country, DL 2474's record is 9 points better than the US average of 77.6%. That gap is worth roughly 85 fewer late arrivals for every thousand flights.

These figures cover 341 flights between July 2025 and June 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.

Schedule

When DL 2474 flies

DL 2474 flies BOS to RSW without a single fixed slot. Its most common scheduled departure was 07:30, used on 95 of 341 flights, with 07:00 (67 flights) and 07:40 (42 flights) next. Carriers retime flights through the season, so the rates here blend slightly different positions in the aircraft's day.

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 3 points worse at 86.1%. Early departures usually start with an aircraft that has not flown yet that day, which is most of why the window does well.

Against the route

DL 2474 next to BOS to RSW

Every carrier on BOS to RSW combined arrived on time 70.5% of the time across 2,253 flights, so DL 2474 is 16 points ahead of it. Delta flew 582 flights on the same city pair under all its flight numbers, including this one, and those ran 77.5% on time. Across its whole network Delta Air Lines managed 81.6%, which this flight beats by 5 points.

Across the year

DL 2474 quarter by quarter

DL 2474 did not run the same all year. Its best quarter was Apr–Jun 2026 at 91.2% on time and its weakest Jan–Mar 2026 at 78.5%, a swing of 13 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 Wednesday at 91.8% on time and worst on Thursday at 79.2%. Each day rests on about 49 flights, so a gap of 13 points is worth noticing but could still narrow in another year.

Delay causes

Why DL 2474 runs late

One category carries most of the weight here. Carrier accounts for 77% of the 3,725 delay minutes carriers reported, and the remaining four split what is left. The split is by minutes rather than by flights, so a few very long delays count for as much as many short ones.

The largest share of delay minutes, 77%, falls under carrier control: crew scheduling, maintenance, fuelling, baggage. Unlike weather, that is a management outcome, and it is the category where the gap between two carriers on the same schedule is genuinely earned. It accounts for 2,876 of the 3,725 delay minutes reported here. The split is drawn from 3,725 delay minutes reported on DL 2474.

Cancellations are rare at 0.88%, below the national 1.81% 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 3.8% land an hour or more behind schedule, against 8.1% 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. It is also long enough that the aircraft usually flies three or four legs a day rather than six, which slows how fast delay compounds.

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: 86.1% on time and 0.88% cancelled. That is a base rate, not a promise about any single day.
