Delay causes
Why DL 1353 runs late
Carriers report a reason for every delay minute they cause, in five DOT categories. The split below is by minutes, not by number of flights, so a handful of very long weather delays weighs as much as many short ones. It covers 4,557 reported delay minutes.
- 41%Late-arriving aircraft
- 29%National Airspace System
- 26%Carrier
- 4%Extreme weather
41% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. Across 4,557 reported delay minutes here, that single category outweighs weather by 10 to one. The split is drawn from 4,557 delay minutes reported on DL 1353.
Cancellations sit at 1.43% against a national 1.89%, which is ordinary. Diversions add another 0.57%.
Connections and routes
What a delay on this flight costs
9.3% 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 526 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 1353 is not only a PIT to ATL flight. It also flew ATL to PIT (350 flights, 85.4% 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. 350 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.
