These figures cover 365 flights between September 2025 and August 2026. On-time means an arrival less than 15 minutes after the scheduled gate time, the same threshold the Department of Transportation uses in its own reports. Cancelled and diverted flights are excluded from the on-time rate and counted separately, which is why the cancellation column matters on its own.

Across the year
DL 1882 quarter by quarter

Share of 362 completed flights by arrival against schedule.
Time lost at the gate mostly stays lost. Of 47 departures that left 15 minutes late or more, only 5 made it up before arrival. In the other direction, 41 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 SJU.
The worst days
Worst days for DL 1882
The latest arrival of the period was on 22 February 2026, 3 hours 13 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 |
|---|---|---|
| 22 February 2026 | 3 hours 13 minutes | Carrier |
| 19 January 2026 | 2 hours 46 minutes | Carrier |
| 14 March 2026 | 2 hours 8 minutes | Carrier |

Delay causes
Why DL 1882 runs late
Carrier accounts for 55% of the 3,176 delay minutes carriers reported here, and the remaining four split what is left.
- 55%Carrier
- 39%National Airspace System
- 5%Late-arriving aircraft
- 0%Extreme weather
The largest share of delay minutes, 55%, falls under carrier control: crew scheduling, maintenance, fuelling, baggage. It accounts for 1,759 of the 3,176 delay minutes reported here. The split is drawn from 3,176 delay minutes reported on DL 1882.
Cancellations are rare at 0.82%, 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 3.0% 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.
At 1,547 miles this is transcontinental flying, and long routes get a quiet structural advantage. Scheduled block time on a flight this length carries more padding in absolute minutes, so a twenty-minute late departure often still becomes an on-time arrival. Read the on-time rate here as slightly flattering next to a short-haul route with the same operational quality.
DL 1882 is not only a ATL to SJU flight. It also flew SJU to ATL (365 flights, 86.9% 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. 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.
