These figures cover 349 flights between September 2025 and August 2026. The median arrival is 17 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 2184 quarter by quarter

The latest arrival of the period was on 3 November 2025, 6 hours 22 minutes behind schedule; most of its delay minutes were filed as extreme weather. Three of the five worst days fell in November 2025.
| Date | Arrived late by | Largest filed cause |
|---|---|---|
| 3 November 2025 | 6 hours 22 minutes | Extreme weather |
| 24 November 2025 | 4 hours 25 minutes | Carrier |
| 12 August 2026 | 3 hours 56 minutes | Extreme weather |

Delay causes
Why DL 2184 runs late
Carrier accounts for 45% of the 3,228 delay minutes carriers reported here, and the remaining four split what is left.
- 45%Carrier
- 29%Extreme weather
- 13%National Airspace System
- 12%Late-arriving aircraft
Extreme weather accounts for 29% of delay minutes, well above the single-digit share typical across the system. Weather delays are lumpy: they arrive as whole bad days rather than as a steady drag, so the quarterly figures above are the more useful view of the risk. The national share is 6%, so this operation carries roughly 4.9 times the usual weather exposure. The split is drawn from 3,228 delay minutes reported on DL 2184.
Cancellations sit at 2.29% against a national 1.89%, which is ordinary. Diversions add another 0.00%.
Connections and routes
What a delay on this flight costs
5.6% 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 an hour and a half, which a normal layover absorbs.
Every one of the 349 flights under DL 2184 in the data flew LEX to ATL. The number was not reused on any other city pair, which makes this a clean record of one route.
One caution: this is a thin sample. 349 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 2184
For a booking, read DL 2184 as 90.0% on time with 2.29% cancelled over 349 flights. Those are rates from the past twelve months, not a forecast for any particular day.
