Historical statistics for July 2025 to June 2026, not live status. For today’s DL 1169, check with Delta Air Lines.
DL 1169 sits in the middle of the pack with a C. About seven flights in ten arrive on time by the DOT's definition, 6 points worse than the national rate of 77.6%. The late ones land roughly 45 minutes behind schedule. That rests on 341 flights, with a median arrival 3 minutes late.
The national on-time rate over the same period is 77.6%, so DL 1169 runs 6 points behind the country as a whole. Across a thousand flights that is about 63 extra late arrivals.

These figures cover 341 flights between July 2025 and June 2026. On-time means an arrival less than 15 minutes after the scheduled gate time, the same threshold the Department of Transportation uses in its own reports. Cancelled and diverted flights are excluded from the on-time rate and counted separately, which is why the cancellation column matters on its own.
Schedule
When DL 1169 flies
DL 1169 flies ATL to PHL without a single fixed slot. Its most common scheduled departure was 15:15, used on 114 of 341 flights, with 15:17 (54 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 15:15 departure sits in the 2pm–5pm window. Across every US flight scheduled in that window the on-time rate is 72.4%, and DL 1169 runs level with that at 71.3%. Midday slots inherit some of the morning's delays without yet carrying the full weight of the evening's.

Across the year
DL 1169 quarter by quarter
Quarter by quarter DL 1169 held fairly steady: 66.7% in Jul–Sep 2025, 72.2% in Oct–Dec 2025, 75.0% in Jan–Mar 2026 and 72.1% in Apr–Jun 2026. A spread of 8 points is about what a sample of this size moves on its own, so the annual figure is a fair summary.

By weekday, DL 1169 did best on Friday at 84.4% on time and worst on Sunday at 61.7%. Each day rests on about 49 flights, so a gap of 23 points is worth noticing but could still narrow in another year.
Delay causes
Why DL 1169 runs late
One category carries most of the weight here. National Airspace System accounts for 53% of the 4,480 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.
- 53%National Airspace System
- 29%Carrier
- 16%Late-arriving aircraft
- 2%Extreme weather
53% of delay minutes are charged to the National Airspace System: air traffic volume, runway configuration, ground stops. No carrier can price its way out of that, which is why airport choice moves the number here more than carrier choice does. That is 2,371 minutes out of 4,480, against a national NAS share of 21%. The split is drawn from 4,480 delay minutes reported on DL 1169.
Cancellations run at 2.93%, against 1.81% nationally. That is roughly one flight in 30 cancelled outright. A cancelled flight is invisible in every on-time figure on this page, so the punctuality numbers above describe only the flights that actually operated.
Connections and routes
What a delay on this flight costs
6.6% 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 roughly 45 minutes, which a normal layover absorbs.
The 666 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 1169 is not only a ATL to PHL flight. It also flew PHL to ATL (291 flights, 75.4% 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. 341 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 1169
For a booking, the cancellation rate is the figure to plan around on DL 1169: 2.93% of its 341 scheduled flights did not operate. A late arrival costs roughly 45 minutes, but a cancellation costs the day, so leave a later option open.
