Historical statistics for July 2025 to June 2026, not live status. For today’s DL 2582, check with Delta Air Lines.

DL 2582 earns an A+. Nearly every flight arrives inside the 15-minute window the DOT uses to define an on-time arrival, which puts it 16 points better than the national rate of 77.6%. When something does go wrong the average delay runs about 2.5 hours. That rests on 314 flights, with a median arrival 16 minutes early.

Set against the rest of the country, DL 2582's record is 16 points better than the US average of 77.6%. That gap is worth roughly 157 fewer late arrivals for every thousand flights.

These figures cover 314 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 2582 flies

DL 2582 flies BUR to SLC without a single fixed slot. Its most common scheduled departure was 07:00, used on 216 of 314 flights, with 07:05 (62 flights) and 07:10 (36 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 2582 runs 4 points better at 93.3%. 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 2582 next to BUR to SLC

Across the year

DL 2582 quarter by quarter

Quarter by quarter DL 2582 held fairly steady: 92.3% in Jul–Sep 2025, 91.3% in Oct–Dec 2025, 93.0% in Jan–Mar 2026 and 97.0% in Apr–Jun 2026. A spread of 6 points is about what a sample of this size moves on its own, so the annual figure is a fair summary.

Jul–Sep 202591 flights92.3%
Oct–Dec 202570 flights91.3%
Jan–Mar 202686 flights93.0%
Apr–Jun 202667 flights97.0%

Scale runs 85% to 100%. Rows with fewer than 30 flights show a dash.

By weekday, DL 2582 ranged from 89.4% on Thursday to 97.8% on Monday. With about 45 flights behind each day, a spread of 8 points is inside normal variation, so the day you fly is not worth changing for this flight.

Delay causes

Why DL 2582 runs late

Carriers report a reason for every delay minute they cause, in five DOT categories. The split below is by minutes, not by number of flights, so a handful of very long weather delays weighs as much as many short ones. It covers 3,131 reported delay minutes.

Extreme weather
34%
Late-arriving aircraft
34%
Carrier
22%
National Airspace System
9%

Extreme weather accounts for 34% 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 5.5 times the usual weather exposure. The split is drawn from 3,131 delay minutes reported on DL 2582.

Cancellations are rare at 0.32%, below the national 1.81% 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 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 574 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 four other city pairs in the data, including DTW to PHL (20), PHL to DTW (20) and DTW to ALB (15), but none flew often enough under DL 2582 to report a rate for. Carriers move flight numbers between routes, so the figures on this page apply to BUR to SLC only.

One caution: this is a thin sample. 314 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 2582

For a booking, DL 2582 has one of the better records a US domestic flight can show: 93.3% on time and 0.32% cancelled. That is a base rate, not a promise about any single day.
