These figures cover 296 flights between September 2025 and August 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.

Across the year
DL 1681 quarter by quarter
DL 1681 did not run the same all year. Its best quarter was Oct–Dec 2025 at 89.3% on time and its weakest Jul–Sep 2026 at 77.4%, a swing of 12 points on roughly 74 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 1681 did best on Tuesday at 91.1% on time and worst on Monday at 72.7%. Each day rests on about 42 flights, so a gap of 18 points is worth noticing but could still narrow in another year.

Connections and routes
What a delay on this flight costs
Badly late arrivals are rare here: only 4.8% 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.
The same number turns up on two other city pairs in the data, including MEM to ATL (233) and FLL to JFK (16), but none flew often enough under DL 1681 to report a rate for. Carriers move flight numbers between routes, so the figures on this page apply to ATL to MEM only.
One caution: this is a thin sample. 296 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 1681
For a booking, read DL 1681 as 83.7% on time with 2.36% cancelled over 296 flights. Those are rates from the past twelve months, not a forecast for any particular day.
