These figures cover 365 flights between September 2025 and August 2026. The median arrival is 5 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.

Across the year
DL 1332 quarter by quarter
DL 1332 did not run the same all year. Its best quarter was Oct–Dec 2025 at 85.9% on time and its weakest Jan–Mar 2026 at 75.0%, a swing of 11 points on roughly 91 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 1332 did best on Wednesday at 90.2% on time and worst on Saturday at 78.0%. Each day rests on about 52 flights, so a gap of 12 points is worth noticing but could still narrow in another year.

Share of 359 completed flights by arrival against schedule.
13 of 51 late departures made up the time and arrived on time, 25% of them. In the other direction, 26 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 latest arrival of the period was on 7 December 2025, 3 hours 55 minutes behind schedule; most of its delay minutes were filed as a late-arriving aircraft. The five worst days are spread across December, July, November, March and January, with no single month standing out.
| Date | Arrived late by | Largest filed cause |
|---|---|---|
| 7 December 2025 | 3 hours 55 minutes | Late-arriving aircraft |
| 30 July 2026 | 3 hours 43 minutes | Extreme weather |
| 9 November 2025 | 3 hours 40 minutes | Carrier |

Delay causes
Why DL 1332 runs late
Carrier accounts for 49% of the 3,465 delay minutes carriers reported here, and the remaining four split what is left.
- 49%Carrier
- 31%National Airspace System
- 11%Late-arriving aircraft
- 9%Extreme weather
The largest share of delay minutes, 49%, falls under carrier control: crew scheduling, maintenance, fuelling, baggage. It accounts for 1,696 of the 3,465 delay minutes reported here. The split is drawn from 3,465 delay minutes reported on DL 1332.
Cancellations sit at 1.37% against a national 1.89%, which is ordinary. Diversions add another 0.27%.
Connections and routes
What a delay on this flight costs
5.0% of arrivals land an hour or more late, close to the national 8.3%, so a 60 to 75 minute layover is reasonable here while anything under 45 minutes is a bet. Most delays on this route last about 55 minutes, which a normal layover absorbs.
The 594 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 1332 is not only a ATL to MIA flight. It also flew MIA to ATL (365 flights, 73.7% 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. 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.
