These figures cover 262 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.

Delay causes
Why DL 995 runs late
Late-arriving aircraft accounts for 55% of the 1,489 delay minutes carriers reported here, and the remaining four split what is left.
- 55%Late-arriving aircraft
- 27%Carrier
- 18%National Airspace System
55% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. Across 1,489 reported delay minutes here, that single category outweighs weather by 55 to one. The split is drawn from 1,489 delay minutes reported on DL 995.
Cancellations sit at 1.15% against a national 1.89%, which is ordinary. Diversions add another 0.38%.
Connections and routes
What a delay on this flight costs
Badly late arrivals are rare here: only 1.6% 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 1,199 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 one other city pair in the data, including ATL to DEN (219), but none flew often enough under DL 995 to report a rate for. Carriers move flight numbers between routes, so the figures on this page apply to DEN to ATL only.
One caution: this is a thin sample. 262 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 995
For a booking, DL 995 has one of the better records a US domestic flight can show: 86.0% on time and 1.15% cancelled. That is a base rate, not a promise about any single day.
