These figures cover 278 flights between September 2025 and August 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.

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 Jul–Sep 2026 at 72.5%, a swing of 22 points on roughly 70 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 90.2% on time and worst on Friday at 72.1%. Each day rests on about 40 flights, so a gap of 18 points is worth noticing but could still narrow in another year.

The worst days
Worst days for DL 1109
The latest arrival of the period was on 9 July 2026, 6 hours 37 minutes behind schedule; most of its delay minutes were filed as carrier-caused (crew, maintenance, fuelling, baggage). The same cause led on four of the five worst days.
| Date | Arrived late by | Largest filed cause |
|---|---|---|
| 9 July 2026 | 6 hours 37 minutes | Carrier |
| 11 August 2026 | 5 hours 29 minutes | Extreme weather |
| 4 August 2026 | 5 hours 20 minutes | Carrier |

Delay causes
Why DL 1109 runs late
Carrier accounts for 61% of the 2,922 delay minutes carriers reported here, and the remaining four split what is left.
- 61%Carrier
- 16%Extreme weather
- 15%National Airspace System
- 7%Late-arriving aircraft
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 2,922 delay minutes reported on DL 1109.
Cancellations sit at 1.80% against a national 1.89%, 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 4.0% 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 1,269 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.
DL 1109 is not only a ATL to ABQ flight. It also flew ABQ to ATL (270 flights, 86.0% 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. 278 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.
