Historical statistics for July 2025 to June 2026, not live status. For today’s DL 2320, check with Delta Air Lines.
DL 2320 earns an A−. Close to nine flights in ten arrive inside the 15-minute window the DOT uses to define an on-time arrival, which puts it 12 points better than the national rate of 77.6%. When something does go wrong the average delay runs about 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 12 points better than the US average of 77.6%. That gap is worth roughly 121 fewer late arrivals for every thousand flights.

These figures cover 365 flights between July 2025 and June 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.
Schedule
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 148 of 365 flights, with 07:05 (92 flights) and 07:10 (41 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 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 level with that at 89.7%. Early departures usually start with an aircraft that has not flown yet that day, which is most of why the window does well.
Against the route
DL 2320 next to JFK to RSW
Every carrier on JFK to RSW combined arrived on time 78.8% of the time across 1,281 flights, so DL 2320 is 11 points ahead of it. Across its whole network Delta Air Lines managed 81.6%, which this flight beats by 8 points.

Across the year
DL 2320 quarter by quarter
DL 2320 did not run the same all year. Its best quarter was Apr–Jun 2026 at 96.6% on time and its weakest Jan–Mar 2026 at 79.3%, a swing of 17 points on roughly 91 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 202592 flights95.6%
- Oct–Dec 202592 flights86.5%
- Jan–Mar 202690 flights79.3%
- Apr–Jun 202691 flights96.6%
Scale runs 70% to 100%. Rows with fewer than 30 flights show a dash.
By weekday, DL 2320 ranged from 86.0% on Friday to 92.0% on Saturday. With about 52 flights behind each day, a spread of 6 points is inside normal variation, so the day you fly is not worth changing for this flight.
Delay causes
Why DL 2320 runs late
One category carries most of the weight here. Carrier accounts for 46% of the 2,395 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.
- 46%Carrier
- 33%National Airspace System
- 20%Late-arriving aircraft
33% 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 802 minutes out of 2,395, against a national NAS share of 21%. The split is drawn from 2,395 delay minutes reported on DL 2320.
Cancellations run at 4.11%, against 1.81% nationally. That is about one flight in 25 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 3.4% land an hour or more behind schedule, against 8.1% 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. 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.
The same number turns up on one other city pair in the data, including RSW to JFK (172), 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: 4.11% of its 365 scheduled flights did not operate. A late arrival costs about an hour, but a cancellation costs the day, so leave a later option open.
