Historical statistics for July 2025 to June 2026, not live status. For today’s DL 2042, check with Delta Air Lines.

DL 2042 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 10 points better than the national rate of 77.6%. When something does go wrong the average delay runs a little over an hour. That rests on 360 flights, with a median arrival 12 minutes early.

Set against the rest of the country, DL 2042's record is 10 points better than the US average of 77.6%. That gap is worth roughly 96 fewer late arrivals for every thousand flights.

These figures cover 360 flights between July 2025 and June 2026. The median arrival is 12 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 2042 flies

DL 2042 flies JFK to TPA without a single fixed slot. Its most common scheduled departure was 07:00, used on 121 of 360 flights, with 07:05 (98 flights) and 07:15 (45 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 2042 runs 2 points worse at 87.2%. 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 2042 next to JFK to TPA

Every carrier on JFK to TPA combined arrived on time 77.1% of the time across 2,301 flights, so DL 2042 is 10 points ahead of it. Delta flew 1,094 flights on the same city pair under all its flight numbers, including this one, and those ran 79.6% on time. Across its whole network Delta Air Lines managed 81.6%, which this flight beats by 6 points.

Across the year

DL 2042 quarter by quarter

DL 2042 did not run the same all year. Its best quarter was Apr–Jun 2026 at 93.2% on time and its weakest Jan–Mar 2026 at 77.4%, a swing of 16 points on roughly 90 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 70% to 100%. Rows with fewer than 30 flights show a dash.

By weekday, DL 2042 did best on Saturday at 97.8% on time and worst on Sunday at 76.5%. Each day rests on about 51 flights, so a gap of 21 points is worth noticing but could still narrow in another year.

Delay causes

Why DL 2042 runs late

One category carries most of the weight here. Carrier accounts for 63% of the 3,569 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.

Carrier
63%
National Airspace System
24%
Late-arriving aircraft
11%
Extreme weather
2%

The largest share of delay minutes, 63%, falls under carrier control: crew scheduling, maintenance, fuelling, baggage. Unlike weather, that is a management outcome, and it is the category where the gap between two carriers on the same schedule is genuinely earned. It accounts for 2,244 of the 3,569 delay minutes reported here. The split is drawn from 3,569 delay minutes reported on DL 2042.

Cancellations sit at 2.22% against a national 1.81%, which is ordinary. Diversions add another 0.00%.

Connections and routes

What a delay on this flight costs

5.1% of arrivals land an hour or more late, close to the national 8.1%. That is the figure that decides a connection, and it says a 60 to 75 minute layover is reasonable here while anything under 45 minutes is a bet. Most delays on this route last a little over an hour, which a normal layover absorbs.

The 1,005 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 TPA to JFK (233), but none flew often enough under DL 2042 to report a rate for. Carriers move flight numbers between routes, so the figures on this page apply to JFK to TPA only.

One caution: this is a thin sample. 360 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 2042

For a booking, read DL 2042 as 87.2% on time with 2.22% cancelled over 360 flights. Those are rates from the past twelve months, not a forecast for any particular day.
