DL 2342 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 an hour and a half. That rests on 346 flights, with a median arrival 16 minutes early.
Set against the rest of the country, DL 2342'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 346 flights between July 2025 and June 2026. The median arrival is 16 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 2342 flies
DL 2342 flies JFK to ATL without a single fixed slot. Its most common scheduled departure was 12:25, used on 89 of 346 flights, with 12:29 (64 flights) next. Carriers retime flights through the season, so the rates here blend slightly different positions in the aircraft's day.
- Departs 12:2589 flights25.7%
- Departs 12:2964 flights18.5%
Scale runs 0% to 100%. Rows with fewer than 30 flights show a dash.
Share of scheduled departures at each local time. Times used on fewer than one flight in ten are not listed.
A 12:25 departure sits in the 11am–2pm window. Across every US flight scheduled in that window the on-time rate is 78.8%, and DL 2342 runs 11 points better at 89.7%. Midday slots inherit some of the morning's delays without yet carrying the full weight of the evening's.

Across the year
DL 2342 quarter by quarter
Quarter by quarter DL 2342 held fairly steady: 93.0% in Jul–Sep 2025, 89.0% in Oct–Dec 2025, 85.3% in Jan–Mar 2026 and 91.0% in Apr–Jun 2026. A spread of 8 points is about what a sample of this size moves on its own, so the annual figure is a fair summary.
- Jul–Sep 202588 flights93.0%
- Oct–Dec 202591 flights89.0%
- Jan–Mar 202678 flights85.3%
- Apr–Jun 202689 flights91.0%
Scale runs 75% to 100%. Rows with fewer than 30 flights show a dash.
By weekday, DL 2342 did best on Wednesday at 96.2% on time and worst on Saturday at 81.8%. Each day rests on about 49 flights, so a gap of 14 points is worth noticing but could still narrow in another year.
Delay causes
Why DL 2342 runs late
One category carries most of the weight here. Carrier accounts for 45% of the 3,048 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.
- 45%Carrier
- 38%Late-arriving aircraft
- 13%National Airspace System
- 4%Extreme weather
38% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. That is a cascade, and cascades start small and grow through the day. Across 3,048 reported delay minutes here, that single category outweighs weather by 8 to one. It is the strongest argument for booking the first departure of the morning, when the aircraft has been sitting at the gate overnight with nothing to inherit. The split is drawn from 3,048 delay minutes reported on DL 2342.
Cancellations are rare at 0.87%, below the national 1.81% 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 4.4% 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 760 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.
Every one of the 346 flights under DL 2342 in the data flew JFK to ATL. The number was not reused on any other city pair, which makes this a clean record of one route.
One caution: this is a thin sample. 346 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 2342
For a booking, DL 2342 has one of the better records a US domestic flight can show: 89.7% on time and 0.87% cancelled. That is a base rate, not a promise about any single day.
