These figures cover 298 flights between September 2025 and August 2026. The median arrival is 11 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.

Share of scheduled departures at each local time. Times used on fewer than one flight in ten are not listed.
A 07:00 departure sits in the 5am–8am window. Across every US flight scheduled in that window the on-time rate is 89.3%, and DL 1600 runs level with that at 89.1%. 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 1600 quarter by quarter
DL 1600 did not run the same all year. Its best quarter was Oct–Dec 2025 at 94.0% on time and its weakest Jan–Mar 2026 at 82.0%, a swing of 12 points on roughly 75 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.

- Apr–Jun 202660 flights93.2%

Scale runs 75% to 100%.
By weekday, DL 1600 did best on Friday at 97.6% on time and worst on Saturday at 82.9%. Each day rests on about 43 flights, so a gap of 15 points is worth noticing but could still narrow in another year.

The worst days
Worst days for DL 1600
The latest arrival of the period was on 1 August 2026, 5 hours 17 minutes behind schedule; most of its delay minutes were filed as a late-arriving aircraft. On three of the five worst days the largest share was filed as carrier-caused (crew, maintenance, fuelling, baggage).
| Date | Arrived late by | Largest filed cause |
|---|---|---|
| 1 August 2026 | 5 hours 17 minutes | Late-arriving aircraft |
| 26 March 2026 | 5 hours 11 minutes | Carrier |
| 16 March 2026 | 3 hours 48 minutes | Late-arriving aircraft |

Delay causes
Why DL 1600 runs late
Carrier accounts for 50% of the 2,124 delay minutes carriers reported here, and the remaining four split what is left.
- 50%Carrier
- 31%Late-arriving aircraft
- 16%National Airspace System
- 3%Extreme weather
The largest share of delay minutes, 50%, falls under carrier control: crew scheduling, maintenance, fuelling, baggage. It accounts for 1,055 of the 2,124 delay minutes reported here. The split is drawn from 2,124 delay minutes reported on DL 1600.
Cancellations are rare at 0.34%, 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 3.1% 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 879 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.
The same number turns up on one other city pair in the data, including RSW to CVG (200), but none flew often enough under DL 1600 to report a rate for. Carriers move flight numbers between routes, so the figures on this page apply to CVG to RSW only.
One caution: this is a thin sample. 298 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 1600
For a booking, DL 1600 has one of the better records a US domestic flight can show: 89.1% on time and 0.34% cancelled. That is a base rate, not a promise about any single day.
