DL 2320 earns an A−. More than four flights in five arrive inside the 15-minute window the DOT uses to define an on-time arrival, which puts it 9 points better than the national rate of 77.3%. When something does go wrong the average delay runs a little over an hour. That rests on 365 flights, with a median arrival 14 minutes early.
Set against the rest of the country, DL 2320's record is 9 points better than the US average of 77.3%. That gap is worth roughly 94 fewer late arrivals for every thousand flights.

These figures cover 365 flights between September 2025 and August 2026. The median arrival is 14 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.

When DL 2320 flies
DL 2320 flies JFK to RSW without a single fixed slot. Its most common scheduled departure was 07:00, used on 130 of 365 flights, with 07:05 (92 flights) and 08:10 (69 flights) next.

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 2320 runs 3 points worse at 86.7%. 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 2320 quarter by quarter
DL 2320 did not run the same all year. Its best quarter was Jul–Sep 2025 at 96.7% on time and its weakest Jul–Sep 2026 at 77.6%, a swing of 19 points on roughly 73 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 202530 flights96.7%
- Oct–Dec 202592 flights86.5%
- Jan–Mar 202690 flights79.3%
- Apr–Jun 202691 flights96.6%

Scale runs 70% to 100%.
By weekday, DL 2320 did best on Saturday at 91.8% on time and worst on Friday at 77.6%. Each day rests on about 52 flights, so a gap of 14 points is worth noticing but could still narrow in another year.
Arrival by arrival
How late DL 2320 runs when it is late
DL 2320 often beats the schedule: 162 of 346 completed flights, 47%, arrived 15 minutes or more early. The 46 late arrivals split 20 under half an hour, 11 between 30 and 60 minutes, and 15 an hour or more.

Share of 346 completed flights by arrival against schedule.
5 of 23 late departures made up the time and arrived on time, 22% of them. In the other direction, 28 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 RSW.
The worst days
Worst days for DL 2320
The latest arrival of the period was on 7 August 2026, 9 hours 5 minutes behind schedule; most of its delay minutes were filed as national airspace system delay. The five worst days are spread across August, December and March, with no single month standing out.
| Date | Arrived late by | Largest filed cause |
|---|---|---|
| 7 August 2026 | 9 hours 5 minutes | National Airspace System |
| 27 December 2025 | 4 hours 37 minutes | Late-arriving aircraft |
| 3 August 2026 | 4 hours 7 minutes | National Airspace System |
| 8 March 2026 | 3 hours 32 minutes | Carrier |
| 15 December 2025 | 3 hours 28 minutes | Late-arriving aircraft |
Delay causes
Why DL 2320 runs late
National Airspace System accounts for 56% of the 3,259 delay minutes carriers reported here, and the remaining four split what is left.
- 56%National Airspace System
- 26%Carrier
- 19%Late-arriving aircraft
56% 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 1,812 minutes out of 3,259, against a national NAS share of 21%. The split is drawn from 3,259 delay minutes reported on DL 2320.
Cancellations run at 4.93%, against 1.89% nationally. That is about one flight in twenty 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
Badly late arrivals are rare here: only 4.3% 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 1,074 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 JFK (193), but none flew often enough under DL 2320 to report a rate for. Carriers move flight numbers between routes, so the figures on this page apply to JFK to RSW only.
One caution: this is a thin sample. 365 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 2320
For a booking, the cancellation rate is the figure to plan around on DL 2320: 4.93% of its 365 scheduled flights did not operate. A late arrival costs a little over an hour, but a cancellation costs the day, so leave a later option open.
