These figures cover 356 flights between September 2025 and August 2026. The median arrival is 6 minutes early, which is the part an average hides: most flights here are fine, and the on-time rate is decided by a tail of badly late ones. On-time means under 15 minutes late, the DOT's own threshold.

DL 2911 quarter by quarter

By weekday, DL 2911 did best on Wednesday at 90.0% on time and worst on Sunday at 69.4%. Each day rests on about 51 flights, so a gap of 21 points is worth noticing but could still narrow in another year.

- 58%Carrier
- 21%Late-arriving aircraft
- 16%National Airspace System
- 5%Extreme weather
The largest share of delay minutes, 58%, falls under carrier control: crew scheduling, maintenance, fuelling, baggage. It accounts for 2,430 of the 4,195 delay minutes reported here. The split is drawn from 4,195 delay minutes reported on DL 2911.

Connections and routes
What a delay on this flight costs
6.1% 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 about an hour, which a normal layover absorbs.
The 692 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.
The same number turns up on one other city pair in the data, including ATL to LEX (1), but none flew often enough under DL 2911 to report a rate for. Carriers move flight numbers between routes, so the figures on this page apply to ATL to MCI only.
One caution: this is a thin sample. 356 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 2911
