These figures cover 361 flights between September 2025 and August 2026. The median arrival is 7 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.

| 8 March 2026 | 4 hours 30 minutes | Late-arriving aircraft |

Delay causes
Why DL 2755 runs late
Late-arriving aircraft accounts for 43% of the 2,618 delay minutes carriers reported here, and the remaining four split what is left.
- 43%Late-arriving aircraft
- 38%Carrier
- 9%National Airspace System
- 9%Extreme weather
43% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. Across 2,618 reported delay minutes here, that single category outweighs weather by 5 to one. The split is drawn from 2,618 delay minutes reported on DL 2755.
Cancellations sit at 1.66% against a national 1.89%, which is ordinary. Diversions add another 0.83%.
Connections and routes
What a delay on this flight costs
Badly late arrivals are rare here: only 3.7% land an hour or more behind schedule, against 8.3% nationally. Connections built on this flight are about as safe as US domestic connections get, though a cancelled flight still ignores every layover you give it.
The 516 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 2755 is not only a ATL to ORF flight. It also flew ORF to ATL (361 flights, 87.6% 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. 361 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.
