Across the year
DL 1169 quarter by quarter

Share of 327 completed flights by arrival against schedule.
Time lost at the gate mostly stays lost. Of 82 departures that left 15 minutes late or more, only 8 made it up before arrival. In the other direction, 24 flights left on time yet arrived 15 minutes late or more, so that delay built up after pushback: in the air, in a holding pattern or on the ground at PHL.

Delay causes
Why DL 1169 runs late
National Airspace System accounts for 51% of the 6,313 delay minutes carriers reported here, and the remaining four split what is left.
- 51%National Airspace System
- 29%Carrier
- 18%Late-arriving aircraft
- 3%Extreme weather
51% 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 3,195 minutes out of 6,313, against a national NAS share of 21%. The split is drawn from 6,313 delay minutes reported on DL 1169.
Cancellations run at 4.11%, against 1.89% nationally. That is about one flight in 25 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
10.4% of arrivals land a full hour or more behind schedule, against 8.3% nationally. Ninety minutes is the honest minimum for a connection here, and two hours if the onward flight is on a separate ticket.
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.
DL 1169 is not only a ATL to PHL flight. It also flew PHL to ATL (256 flights, 77.9% 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.
