These figures cover 349 flights between July 2025 and June 2026. The median arrival is 19 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 2184 flies
DL 2184 flies LEX to ATL without a single fixed slot. Its most common scheduled departure was 06:00, used on 256 of 349 flights, with 05:50 (41 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 06:00 departure sits in the 5am–8am window. Across every US flight scheduled in that window the on-time rate is 89.3%, and DL 2184 runs 3 points better at 91.8%. Early departures usually start with an aircraft that has not flown yet that day, which is most of why the window does well.

Across the year
DL 2184 quarter by quarter
DL 2184 did not run the same all year. Its best quarter was Jul–Sep 2025 at 97.8% on time and its weakest Oct–Dec 2025 at 83.1%, a swing of 15 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.
- Jul–Sep 202592 flights97.8%
- Oct–Dec 202580 flights83.1%
- Jan–Mar 202686 flights89.0%
- Apr–Jun 202691 flights95.6%
Scale runs 75% to 100%. Rows with fewer than 30 flights show a dash.
By weekday, DL 2184 ranged from 85.1% on Monday to 96.0% on Thursday. With about 50 flights behind each day, a spread of 11 points is inside normal variation, so the day you fly is not worth changing for this flight.
Delay causes
Why DL 2184 runs late
Carriers report a reason for every delay minute they cause, in five DOT categories. The split below is by minutes, not by number of flights, so a handful of very long weather delays weighs as much as many short ones. It covers 2,675 reported delay minutes.
- 36%Carrier
- 26%Extreme weather
- 22%Late-arriving aircraft
- 15%National Airspace System
Extreme weather accounts for 26% 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 4.2 times the usual weather exposure. The split is drawn from 2,675 delay minutes reported on DL 2184.
Cancellations sit at 2.29% against a national 1.81%, which is ordinary. Diversions add another 0.00%.
Connections and routes
What a delay on this flight costs
Badly late arrivals are rare here: only 4.7% 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.
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
