These figures cover 346 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 1472 flies
DL 1472 flies ATL to EYW without a single fixed slot. Its most common scheduled departure was 11:12, used on 89 of 346 flights, with 11:58 (62 flights) and 12:15 (44 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 11:12 departure sits in the 11am–2pm window. Across every US flight scheduled in that window the on-time rate is 78.8%, and DL 1472 runs 6 points better at 85.2%. Midday slots inherit some of the morning's delays without yet carrying the full weight of the evening's.

Across the year
DL 1472 quarter by quarter
DL 1472 did not run the same all year. Its best quarter was Apr–Jun 2026 at 94.2% on time and its weakest Jan–Mar 2026 at 78.3%, a swing of 16 points on roughly 87 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 1472 did best on Thursday at 96.0% on time and worst on Monday at 73.9%. Each day rests on about 49 flights, so a gap of 22 points is worth noticing but could still narrow in another year.
Delay causes
Why DL 1472 runs late
One category carries most of the weight here. Carrier accounts for 59% of the 2,370 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.
- 59%Carrier
- 32%National Airspace System
- 8%Late-arriving aircraft
- 1%Extreme weather
The largest share of delay minutes, 59%, 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 1,395 of the 2,370 delay minutes reported here. The split is drawn from 2,370 delay minutes reported on DL 1472.
Cancellations sit at 1.16% against a national 1.81%, which is ordinary. Diversions add another 1.16%.
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 646 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.
DL 1472 is not only a ATL to EYW flight. It also flew EYW to ATL (346 flights, 83.4% 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. 346 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.
