Historical statistics for July 2025 to June 2026, not live status. For today’s DL 995, check with Delta Air Lines.
DL 995 earns an A. More than four flights in five arrive inside the 15-minute window the DOT uses to define an on-time arrival, which puts it 9 points better than the national rate of 77.6%. When something does go wrong the average delay runs about 40 minutes. That rests on 324 flights, with a median arrival 11 minutes early.
Set against the rest of the country, DL 995's record is 9 points better than the US average of 77.6%. That gap is worth roughly 92 fewer late arrivals for every thousand flights.

These figures cover 324 flights between July 2025 and June 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 995 flies
DL 995 flies DEN to ATL without a single fixed slot. Its most common scheduled departure was 12:10, used on 66 of 324 flights, with 12:00 (62 flights) and 11:43 (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 12:10 departure sits in the 11am–2pm window. Across every US flight scheduled in that window the on-time rate is 78.8%, and DL 995 runs 8 points better at 86.8%. Midday slots inherit some of the morning's delays without yet carrying the full weight of the evening's.

Across the year
DL 995 quarter by quarter
DL 995 did not run the same all year. Its best quarter was Apr–Jun 2026 at 94.2% on time and its weakest Jan–Mar 2026 at 81.1%, a swing of 13 points on roughly 81 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 flights92.2%
- Oct–Dec 202589 flights82.6%
- Jan–Mar 202690 flights81.1%
- Apr–Jun 202653 flights94.2%
Scale runs 75% to 100%. Rows with fewer than 30 flights show a dash.
By weekday, DL 995 ranged from 83.0% on Tuesday to 93.5% on Thursday. With about 46 flights behind each day, a spread of 11 points is inside normal variation, so the day you fly is not worth changing for this flight.
Delay causes
Why DL 995 runs late
One category carries most of the weight here. Late-arriving aircraft accounts for 52% of the 1,721 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.
- 52%Late-arriving aircraft
- 31%Carrier
- 18%National Airspace System
52% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. That is a cascade, and cascades start small and grow through the day. Across 1,721 reported delay minutes here, that single category outweighs weather by 52 to one. It is the strongest argument for booking the first departure of the morning, when the aircraft has been sitting at the gate overnight with nothing to inherit. The split is drawn from 1,721 delay minutes reported on DL 995.
Cancellations sit at 1.23% against a national 1.81%, which is ordinary. Diversions add another 0.62%.
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 8.1% 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 1,199 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. 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 one other city pair in the data, including ATL to DEN (209), 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. 324 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: 86.8% on time and 1.23% cancelled. That is a base rate, not a promise about any single day.
