Across the year
DL 360 quarter by 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 360 did best on Saturday at 82.4% on time and worst on Thursday at 63.5%. Each day rests on about 52 flights, so a gap of 19 points is worth noticing but could still narrow in another year.

11 of 75 late departures made up the time and arrived on time, 15% of them. In the other direction, 45 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 DCA.

Delay causes

- 46%Carrier
- 43%National Airspace System
- 7%Late-arriving aircraft
- 4%Extreme weather
The largest share of delay minutes, 46%, falls under carrier control: crew scheduling, maintenance, fuelling, baggage. It accounts for 2,835 of the 6,199 delay minutes reported here. The split is drawn from 6,199 delay minutes reported on DL 360.
Cancellations sit at 1.10% against a national 1.89%, which is ordinary. Diversions add another 0.00%.
Connections and routes
What a delay on this flight costs
9.7% 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 547 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 360 is not only a ATL to DCA flight. It also flew DCA to ATL (336 flights, 69.3% 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. 364 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.
