Historical statistics for July 2025 to June 2026, not live status. For today’s DL 1004, check with Delta Air Lines.

DL 1004 earns an A. Close to nine flights in ten arrive inside the 15-minute window the DOT uses to define an on-time arrival, which puts it 13 points better than the national rate of 77.6%. When something does go wrong the average delay runs an hour and a half. That rests on 340 flights, with a median arrival 14 minutes early.

Set against the rest of the country, DL 1004's record is 13 points better than the US average of 77.6%. That gap is worth roughly 125 fewer late arrivals for every thousand flights.

These figures cover 340 flights between July 2025 and June 2026. The median arrival is 14 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 1004 flies

DL 1004 flies ABQ to ATL without a single fixed slot. Its most common scheduled departure was 11:09, used on 42 of 340 flights, with 14:00 (40 flights) and 11:25 (37 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 11:09 departure sits in the 11am–2pm window. Across every US flight scheduled in that window the on-time rate is 78.8%, and DL 1004 runs 11 points better at 90.1%. Midday slots inherit some of the morning's delays without yet carrying the full weight of the evening's.

Across the year

DL 1004 quarter by quarter

Quarter by quarter DL 1004 held fairly steady: 90.9% in Jul–Sep 2025, 87.8% in Oct–Dec 2025, 88.4% in Jan–Mar 2026 and 93.3% 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.

By weekday, DL 1004 did best on Wednesday at 95.7% on time and worst on Monday at 81.2%. Each day rests on about 49 flights, so a gap of 15 points is worth noticing but could still narrow in another year.

Delay causes

Why DL 1004 runs late

One category carries most of the weight here. Carrier accounts for 45% of the 3,175 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.

Carrier
45%
Late-arriving aircraft
36%
National Airspace System
17%
Extreme weather
2%

36% 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 3,175 reported delay minutes here, that single category outweighs weather by 20 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 3,175 delay minutes reported on DL 1004.

Cancellations sit at 1.76% against a national 1.81%, which is ordinary. Diversions add another 0.00%.

Connections and routes

What a delay on this flight costs

Badly late arrivals are rare here: only 2.4% 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 1,269 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.

DL 1004 is not only a ABQ to ATL flight. It also flew ATL to ABQ (332 flights, 92.3% on time) often enough to be scored on its own. Airlines attach one number to several legs of an aircraft's day, and each leg keeps its own record here, so check which city pair is on your booking before reading a rate.

One caution: this is a thin sample. 340 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

For a booking, read DL 1004 as 90.1% on time with 1.76% cancelled over 340 flights. Those are rates from the past twelve months, not a forecast for any particular day.
