These figures cover 315 flights between September 2025 and August 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.

|---|---|---|
| 18 September 2025 | 8 hours 44 minutes | Extreme weather |
| 9 November 2025 | 7 hours 25 minutes | Extreme weather |

Delay causes
Why DL 2582 runs late
Extreme weather accounts for 49% of the 2,191 delay minutes carriers reported here, and the remaining four split what is left.
- 49%Extreme weather
- 39%Carrier
- 10%National Airspace System
- 3%Late-arriving aircraft
Extreme weather accounts for 49% 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 8.2 times the usual weather exposure. The split is drawn from 2,191 delay minutes reported on DL 2582.
Cancellations are rare at 0.63%, 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 2.9% 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 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.
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. 315 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: 93.6% on time and 0.63% cancelled. That is a base rate, not a promise about any single day.
