Across the year

DL 1685 quarter by quarter

DL 1685 did not run the same all year. Its best quarter was Apr–Jun 2026 at 79.1% on time and its weakest Jul–Sep 2026 at 65.5%, a swing of 14 points on roughly 85 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.

Scale runs 55% to 85%. Rows with fewer than 30 flights show a dash.

By weekday, DL 1685 did best on Wednesday at 88.6% on time and worst on Saturday at 55.9%. Each day rests on about 36 flights, so a gap of 33 points is worth noticing but could still narrow in another year.

Arrival by arrival

How late DL 1685 runs when it is late

DL 1685 often beats the schedule: 96 of 241 completed flights, 40%, arrived 15 minutes or more early. The 61 late arrivals split 13 under half an hour, 25 between 30 and 60 minutes, and 23 an hour or more.

Share of 241 completed flights by arrival against schedule.

13 of 60 late departures made up the time and arrived on time, 22% of them. In the other direction, 14 flights left on time yet arrived 15 minutes late or more, so that delay built up after pushback: in the air, in a holding pattern or on the ground at MCO.

The worst days

Worst days for DL 1685

The latest arrival of the period was on 19 July 2026, 3 hours 10 minutes behind schedule; most of its delay minutes were filed as a late-arriving aircraft. The same cause led on three of the five worst days.

Delay causes

Why DL 1685 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 3,888 reported delay minutes.

National Airspace System
41%
Late-arriving aircraft
29%
Carrier
26%
Extreme weather

Security
1%

41% of delay minutes are charged to the National Airspace System: air traffic volume, runway configuration, ground stops. No carrier can price its way out of that, which is why airport choice moves the number here more than carrier choice does. That is 1,597 minutes out of 3,888, against a national NAS share of 21%. The split is drawn from 3,888 delay minutes reported on DL 1685.

Cancellations run at 3.53%, against 1.89% nationally. That is about one flight in 30 cancelled outright. A cancelled flight is invisible in every on-time figure on this page, so the punctuality numbers above describe only the flights that actually operated.

Connections and routes

What a delay on this flight costs

9.5% of arrivals land a full hour or more behind schedule, against 8.3% nationally. Ninety minutes is the honest minimum for a connection here, and two hours if the onward flight is on a separate ticket.

The 944 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 four other city pairs in the data, including RSW to DTW (74), MCO to JFK (45) and SAT to ATL (5), but none flew often enough under DL 1685 to report a rate for. Carriers move flight numbers between routes, so the figures on this page apply to JFK to MCO only.

One caution: this is a thin sample. 255 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 1685

For a booking, the cancellation rate is the figure to plan around on DL 1685: 3.53% of its 255 scheduled flights did not operate. A late arrival costs about an hour, but a cancellation costs the day, so leave a later option open.
