Historical statistics for July 2025 to June 2026, not live status. For today’s DL 1125, check with Delta Air Lines.

DL 1125 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 a little over an hour. That rests on 361 flights, with a median arrival 19 minutes early.

Set against the rest of the country, DL 1125's record is 9 points better than the US average of 77.6%. That gap is worth roughly 87 fewer late arrivals for every thousand flights.

These figures cover 361 flights between July 2025 and June 2026. The median arrival is 19 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 1125 flies

DL 1125 flies OMA to ATL without a single fixed slot. Its most common scheduled departure was 14:50, used on 60 of 361 flights, with 15:08 (55 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 14:50 departure sits in the 2pm–5pm window. Across every US flight scheduled in that window the on-time rate is 72.4%, and DL 1125 runs 14 points better at 86.3%. Midday slots inherit some of the morning's delays without yet carrying the full weight of the evening's.

Across the year

DL 1125 quarter by quarter

Quarter by quarter DL 1125 held fairly steady: 84.3% in Jul–Sep 2025, 82.6% in Oct–Dec 2025, 88.5% in Jan–Mar 2026 and 89.9% in Apr–Jun 2026. A spread of 7 points is about what a sample of this size moves on its own, so the annual figure is a fair summary.

By weekday, DL 1125 did best on Tuesday at 94.2% on time and worst on Sunday at 79.6%. Each day rests on about 52 flights, so a gap of 15 points is worth noticing but could still narrow in another year.

Delay causes

Why DL 1125 runs late

One category carries most of the weight here. Late-arriving aircraft accounts for 52% of the 3,644 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% 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 3,644 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 3,644 delay minutes reported on DL 1125.

Cancellations sit at 1.94% against a national 1.81%, which is ordinary. Diversions add another 0.83%.

Connections and routes

What a delay on this flight costs

5.4% of arrivals land an hour or more late, close to the national 8.1%. That is the figure that decides a connection, and it says a 60 to 75 minute layover is reasonable here while anything under 45 minutes is a bet. Most delays on this route last a little over an hour, which a normal layover absorbs.

The 821 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 1125 is not only a OMA to ATL flight. It also flew ATL to OMA (358 flights, 85.8% 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. 361 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.
