Historical statistics for July 2025 to June 2026, not live status. For today’s DL 454, check with Delta Air Lines.

DL 454 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 13 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 365 flights, with a median arrival 16 minutes early.

Set against the rest of the country, DL 454's record is 13 points better than the US average of 77.6%. That gap is worth roughly 126 fewer late arrivals for every thousand flights.

These figures cover 365 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 454 flies

DL 454 flies DFW to JFK without a single fixed slot. Its most common scheduled departure was 07:15, used on 66 of 365 flights, with 08:00 (60 flights) next. Carriers retime flights through the season, so the rates here blend slightly different positions in the aircraft's day.

Departs 07:1566 flights18.1%

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 07:15 departure sits in the 5am–8am window. Across every US flight scheduled in that window the on-time rate is 89.3%, and DL 454 runs level with that at 90.2%. 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 454 next to DFW to JFK

Every carrier on DFW to JFK combined arrived on time 77.0% of the time across 2,009 flights, so DL 454 is 13 points ahead of it. Across its whole network Delta Air Lines managed 81.6%, which this flight beats by 9 points.

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 202592 flights90.9%
Oct–Dec 202592 flights82.6%
Jan–Mar 202690 flights92.7%
Apr–Jun 202691 flights94.4%

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

By weekday, DL 454 ranged from 86.3% on Tuesday to 96.0% on Friday. With about 52 flights behind each day, a spread of 10 points is inside normal variation, so the day you fly is not worth changing for this flight.

Delay causes

Why DL 454 runs late

One category carries most of the weight here. Carrier accounts for 48% of the 2,657 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
48%
National Airspace System
26%
Extreme weather
16%
Late-arriving aircraft
11%

Extreme weather accounts for 16% 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 2,657 delay minutes reported on DL 454.

Cancellations run at 5.21%, against 1.81% nationally. That is about one flight in twenty 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 3.8% 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 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. 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 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: 5.21% of its 365 scheduled flights did not operate. A late arrival costs a little over an hour, but a cancellation costs the day, so leave a later option open.
