Across the year
DL 2001 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.

- 4%Extreme weather
The largest share of delay minutes, 56%, falls under carrier control: crew scheduling, maintenance, fuelling, baggage. It accounts for 2,809 of the 5,028 delay minutes reported here. The split is drawn from 5,028 delay minutes reported on DL 2001.

Connections and routes
What a delay on this flight costs
10.1% 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 same number turns up on three other city pairs in the data, including DTW to RSW (29), RSW to DTW (29) and AGS to ATL (9), but none flew often enough under DL 2001 to report a rate for. Carriers move flight numbers between routes, so the figures on this page apply to ATL to MEM only.
One caution: this is a thin sample. 281 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 2001
For a booking, read DL 2001 as 76.2% on time with 1.42% cancelled over 281 flights. Those are rates from the past twelve months, not a forecast for any particular day.
