Historical statistics for July 2025 to June 2026, not live status. For today’s DL 1109, check with Delta Air Lines.
DL 1109 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 roughly 45 minutes. That rests on 277 flights, with a median arrival 8 minutes early.
Set against the rest of the country, DL 1109's record is 9 points better than the US average of 77.6%. That gap is worth roughly 88 fewer late arrivals for every thousand flights.

These figures cover 277 flights between July 2025 and June 2026. The median arrival is 8 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 1109 flies
DL 1109 flies ATL to ABQ without a single fixed slot. Its most common scheduled departure was 14:09, used on 35 of 277 flights, with 14:25 (30 flights) next. Carriers retime flights through the season, so the rates here blend slightly different positions in the aircraft's day.

Scale runs 0% to 100%. Rows with fewer than 30 flights show a dash.
Share of scheduled departures at each local time. Times used on fewer than one flight in ten are not listed.
A 14:09 departure sits in the 2pm–5pm window. Across every US flight scheduled in that window the on-time rate is 72.4%, and DL 1109 runs 14 points better at 86.4%. Midday slots inherit some of the morning's delays without yet carrying the full weight of the evening's.

Across the year
DL 1109 quarter by quarter
DL 1109 did not run the same all year. Its best quarter was Jan–Mar 2026 at 94.1% on time and its weakest Apr–Jun 2026 at 81.3%, a swing of 13 points on roughly 69 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.

By weekday, DL 1109 did best on Wednesday at 95.1% on time and worst on Monday at 78.3%. Each day rests on about 40 flights, so a gap of 17 points is worth noticing but could still narrow in another year.
Delay causes
Why DL 1109 runs late
One category carries most of the weight here. Carrier accounts for 62% of the 1,749 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.
- 62%Carrier
- 24%Late-arriving aircraft
- 9%National Airspace System
- 5%Extreme weather
The largest share of delay minutes, 62%, falls under carrier control: crew scheduling, maintenance, fuelling, baggage. Unlike weather, that is a management outcome, and it is the category where the gap between two carriers on the same schedule is genuinely earned. It accounts for 1,090 of the 1,749 delay minutes reported here. The split is drawn from 1,749 delay minutes reported on DL 1109.
Cancellations sit at 1.44% against a national 1.81%, which is ordinary. Diversions add another 0.36%.
Connections and routes
What a delay on this flight costs
Badly late arrivals are rare here: only 3.7% 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 1109 is not only a ATL to ABQ flight. It also flew ABQ to ATL (269 flights, 86.6% 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. 277 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.
