These figures cover 365 flights between September 2025 and August 2026. The median arrival is 15 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.

Share of scheduled departures at each local time. Times used on fewer than one flight in ten are not listed.
A 08:00 departure sits in the 8am–11am window. Across every US flight scheduled in that window the on-time rate is 83.9%, and DL 454 runs 6 points better at 89.8%. 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 454 quarter by quarter
DL 454 did not run the same all year. Its best quarter was Apr–Jun 2026 at 94.4% on time and its weakest Oct–Dec 2025 at 82.6%, a swing of 12 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 202530 flights—
- Oct–Dec 202592 flights82.6%
- Jan–Mar 202690 flights92.7%
- Apr–Jun 202691 flights94.4%
- Jul–Sep 202662 flights87.3%
Scale runs 75% to 100%. Rows with fewer than 30 flights show a dash.
By weekday, DL 454 did best on Friday at 98.0% on time and worst on Monday at 83.3%. Each day rests on about 52 flights, so a gap of 15 points is worth noticing but could still narrow in another year.

The worst days
Worst days for DL 454
The latest arrival of the period was on 24 August 2026, 6 hours 22 minutes behind schedule; most of its delay minutes were filed as carrier-caused (crew, maintenance, fuelling, baggage). The same cause led on four of the five worst days.
| Date | Arrived late by | Largest filed cause |
|---|---|---|
| 24 August 2026 | 6 hours 22 minutes | Carrier |
| 12 November 2025 | 5 hours 12 minutes | Carrier |
| 19 August 2026 | 4 hours 20 minutes | Carrier |
| 2 December 2025 | 3 hours 59 minutes | Late-arriving aircraft |
| 27 May 2026 | 3 hours 37 minutes | Carrier |
Delay causes
Why DL 454 runs late
Carrier accounts for 57% of the 3,275 delay minutes carriers reported here, and the remaining four split what is left.
- 57%Carrier
- 21%National Airspace System
- 13%Extreme weather
- 9%Late-arriving aircraft
Extreme weather accounts for 13% 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 2.2 times the usual weather exposure. The split is drawn from 3,275 delay minutes reported on DL 454.
Cancellations run at 6.03%, against 1.89% nationally. That is roughly one flight in fifteen 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 4.4% 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 1,391 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.
Every one of the 365 flights under DL 454 in the data flew DFW to JFK. 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. 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 454
For a booking, the cancellation rate is the figure to plan around on DL 454: 6.03% of its 365 scheduled flights did not operate. A late arrival costs an hour and a half, but a cancellation costs the day, so leave a later option open.
