Historical statistics for July 2025 to June 2026, not live status. For today’s DL 1394, check with Delta Air Lines.

DL 1394 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 14 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 335 flights, with a median arrival 9 minutes early.

Set against the rest of the country, DL 1394's record is 14 points better than the US average of 77.6%. That gap is worth roughly 140 fewer late arrivals for every thousand flights.

These figures cover 335 flights between July 2025 and June 2026. The median arrival is 9 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 1394 flies

DL 1394 flies PBI to ATL without a single fixed slot. Its most common scheduled departure was 09:00, used on 114 of 335 flights, with 09:15 (80 flights) and 09:20 (60 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 09:00 departure sits in the 8am–11am window. Across every US flight scheduled in that window the on-time rate is 84.1%, and DL 1394 runs 8 points better at 91.6%. 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 1394 next to PBI to ATL

Every carrier on PBI to ATL combined arrived on time 82.9% of the time across 3,826 flights, so DL 1394 is 9 points ahead of it. Delta flew 3,737 flights on the same city pair under all its flight numbers, including this one, and those ran 84.0% on time. Across its whole network Delta Air Lines managed 81.6%, which this flight beats by 10 points.

Across the year

DL 1394 quarter by quarter

DL 1394 did not run the same all year. Its best quarter was Jul–Sep 2025 at 96.5% on time and its weakest Jan–Mar 2026 at 85.6%, a swing of 11 points on roughly 84 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 202587 flights96.5%
Oct–Dec 202591 flights93.3%
Jan–Mar 202690 flights85.6%
Apr–Jun 202667 flights91.0%

Scale runs 75% to 100%. Rows with fewer than 30 flights show a dash.

By weekday, DL 1394 did best on Saturday at 97.9% on time and worst on Monday at 74.5%. Each day rests on about 48 flights, so a gap of 23 points is worth noticing but could still narrow in another year.

Delay causes

Why DL 1394 runs late

One category carries most of the weight here. Carrier accounts for 56% of the 2,367 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
56%
National Airspace System
19%
Extreme weather
15%
Late-arriving aircraft
10%

Extreme weather accounts for 15% of delay minutes, well above the single-digit share typical across the system. Weather delays are lumpy: they arrive as whole bad days rather than as a steady drag, so the quarterly figures above are the more useful view of the risk. The national share is 6%, so this operation carries roughly 2.4 times the usual weather exposure. The split is drawn from 2,367 delay minutes reported on DL 1394.

Cancellations sit at 0.90% against a national 1.81%, which is ordinary. Diversions add another 0.00%.

Connections and routes

What a delay on this flight costs

Badly late arrivals are rare here: only 3.6% 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 545 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 two other city pairs in the data, including ATL to PBI (58) and MSY to JFK (23), but none flew often enough under DL 1394 to report a rate for. Carriers move flight numbers between routes, so the figures on this page apply to PBI to ATL only.

One caution: this is a thin sample. 335 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 1394

For a booking, DL 1394 has one of the better records a US domestic flight can show: 91.6% on time and 0.90% cancelled. That is a base rate, not a promise about any single day.
