Across the year

Connections and routes
What a delay on this flight costs
8.9% of arrivals land an hour or more late, close to the national 8.3%, so a 60 to 75 minute layover is reasonable here while anything under 45 minutes is a bet. Most delays on this route last a little over an hour, which a normal layover absorbs.
The same number turns up on three other city pairs in the data, including MSP to MCI (60), MCI to MSP (60) and MCO to LGA (41), but none flew often enough under DL 1263 to report a rate for. Carriers move flight numbers between routes, so the figures on this page apply to ATL to RIC only.
One caution: this is a thin sample. 254 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 1263
For a booking, DL 1263 is one of the weaker ways to fly ATL to RIC: 6 points below the route as a whole. If the schedule allows, compare it with the other departures listed on the route page before settling on this one.
