DL 2168 lands a B, about a point better than the national rate of 77.6%. About one flight in five arrives 15 minutes late or worse, and those flights are late by about an hour on average. That is a workable record, not a spotless one. That rests on 353 flights, with a median arrival 6 minutes early.

These figures cover 353 flights between July 2025 and June 2026. The median arrival is 6 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 2168 flies
DL 2168 flies ATL to EYW without a single fixed slot. Its most common scheduled departure was 15:31, used on 56 of 353 flights, with 15:39 (36 flights) and 15:21 (36 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 15:31 departure sits in the 2pm–5pm window. Across every US flight scheduled in that window the on-time rate is 72.4%, and DL 2168 runs 7 points better at 79.0%. Midday slots inherit some of the morning's delays without yet carrying the full weight of the evening's.

Across the year
DL 2168 quarter by quarter
DL 2168 did not run the same all year. Its best quarter was Apr–Jun 2026 at 89.2% on time and its weakest Jan–Mar 2026 at 74.7%, a swing of 15 points on roughly 88 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 2168 did best on Wednesday at 88.0% on time and worst on Sunday at 71.4%. Each day rests on about 50 flights, so a gap of 17 points is worth noticing but could still narrow in another year.
Delay causes
Why DL 2168 runs late
One category carries most of the weight here. Carrier accounts for 45% of the 4,799 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.
- 45%Carrier
- 21%Extreme weather
- 20%National Airspace System
- 14%Late-arriving aircraft
Extreme weather accounts for 21% 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 3.3 times the usual weather exposure. The split is drawn from 4,799 delay minutes reported on DL 2168.
Cancellations sit at 1.13% against a national 1.81%, which is ordinary. Diversions add another 0.28%.
Connections and routes
What a delay on this flight costs
6.0% of arrivals land an hour or more late, close to the national 8.1%. That is the figure that decides a connection, and it says a 60 to 75 minute layover is reasonable here while anything under 45 minutes is a bet. Most delays on this route last about an hour, which a normal layover absorbs.
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 2168 is not only a ATL to EYW flight. It also flew EYW to ATL (352 flights, 82.4% 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. 353 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.
