These figures cover 365 flights between September 2025 and August 2026. The median arrival is 11 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 3085 flies

DL 3085 is scheduled to leave Valparaiso (VPS) at 06:00 local time and reach Atlanta (ATL) at 08:15. That slot held for 365 of the 365 scheduled departures in the data, so the figures below describe one steady operation rather than a number that moved around the clock.

Share of scheduled departures at each local time. Times used on fewer than one flight in ten are not listed.

A 06:00 departure sits in the 5am–8am window. Across every US flight scheduled in that window the on-time rate is 89.3%, and DL 3085 runs level with that at 88.0%. Early departures usually start with an aircraft that has not flown yet that day, which is most of why the window does well.

Delay causes

Why DL 3085 runs late

Carrier accounts for 53% of the 3,712 delay minutes carriers reported here, and the remaining four split what is left.

Late-arriving aircraft

Extreme weather

National Airspace System
15%

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 2.7 times the usual weather exposure. The split is drawn from 3,712 delay minutes reported on DL 3085.

Cancellations sit at 1.37% against a national 1.89%, which is ordinary. Diversions add another 0.27%.

Connections and routes

What a delay on this flight costs

Badly late arrivals are rare here: only 3.9% 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.

Every one of the 365 flights under DL 3085 in the data flew VPS to ATL. 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 3085

For a booking, DL 3085 has one of the better records a US domestic flight can show: 88.0% on time and 1.37% cancelled. That is a base rate, not a promise about any single day.
