These figures cover 278 flights between September 2025 and August 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.

A 09:15 departure sits in the 8am–11am window. Across every US flight scheduled in that window the on-time rate is 83.9%, and DL 1394 runs 7 points better at 90.6%. 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 1394 quarter by quarter
DL 1394 did not run the same all year. Its best quarter was Jul–Sep 2025 at 96.7% on time and its weakest Jan–Mar 2026 at 85.6%, a swing of 11 points on roughly 70 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 202591 flights93.3%
- Jan–Mar 202690 flights85.6%
- Apr–Jun 202667 flights91.0%
Scale runs 75% to 100%.
By weekday, DL 1394 did best on Saturday at 100.0% on time and worst on Monday at 71.8%. Each day rests on about 40 flights, so a gap of 28 points is worth noticing but could still narrow in another year.

The worst days
Worst days for DL 1394
The latest arrival of the period was on 4 May 2026, 6 hours 33 minutes behind schedule; most of its delay minutes were filed as carrier-caused (crew, maintenance, fuelling, baggage). The same cause led on three of the five worst days.
| Date | Arrived late by | Largest filed cause |
|---|---|---|
| 4 May 2026 | 6 hours 33 minutes | Carrier |
| 16 March 2026 | 5 hours 56 minutes | Extreme weather |
| 7 May 2026 | 4 hours 35 minutes | Carrier |
| 2 December 2025 | 2 hours 41 minutes | Carrier |
| 5 January 2026 | 2 hours 10 minutes | National Airspace System |
Delay causes
Why DL 1394 runs late
Carrier accounts for 56% of the 2,325 delay minutes carriers reported here, and the remaining four split what is left.
- 56%Carrier
- 18%National Airspace System
- 15%Extreme weather
- 10%Late-arriving aircraft
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 2.5 times the usual weather exposure. The split is drawn from 2,325 delay minutes reported on DL 1394.
Cancellations are rare at 0.72%, below the national 1.89% 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 4.3% 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 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.
The same number turns up on two other city pairs in the data, including MSY to JFK (84) and ATL to PBI (58), 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. 278 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: 90.6% on time and 0.72% cancelled. That is a base rate, not a promise about any single day.
