These figures cover 365 flights between September 2025 and August 2026. The median arrival is 4 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.

Share of 359 completed flights by arrival against schedule.
Time lost at the gate mostly stays lost. Of 51 departures that left 15 minutes late or more, only 5 made it up before arrival. In the other direction, 19 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 GRR.

Worst days for DL 2865
The latest arrival of the period was on 3 October 2025, 11 hours 16 minutes behind schedule; most of its delay minutes were filed as carrier-caused (crew, maintenance, fuelling, baggage). The same cause led on four of the five worst days.

Delay causes
Why DL 2865 runs late
Carrier accounts for 53% of the 3,958 delay minutes carriers reported here, and the remaining four split what is left.
- 53%Carrier
- 26%National Airspace System
- 17%Late-arriving aircraft
- 4%Extreme weather
The largest share of delay minutes, 53%, falls under carrier control: crew scheduling, maintenance, fuelling, baggage. It accounts for 2,106 of the 3,958 delay minutes reported here. The split is drawn from 3,958 delay minutes reported on DL 2865.

Connections and routes
What a delay on this flight costs
5.0% 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 640 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.
Every one of the 365 flights under DL 2865 in the data flew ATL to GRR. The number was not reused on any other city pair, which makes this a clean record of one route.
One caution: this is a thin sample. 365 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.
