These figures cover 360 flights between September 2025 and August 2026. The median arrival is 10 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.

The worst days

The latest arrival of the period was on 28 April 2026, 4 hours 12 minutes behind schedule; most of its delay minutes were filed as a late-arriving aircraft. The five worst days are spread across April, July, November, March and August, with no single month standing out.
| Date | Arrived late by | Largest filed cause |
|---|---|---|
| 28 April 2026 | 4 hours 12 minutes | Late-arriving aircraft |
| 12 July 2026 | 3 hours 44 minutes | Carrier |
| 29 November 2025 | 2 hours 55 minutes | Carrier |

Delay causes
Why DL 2270 runs late
Late-arriving aircraft accounts for 50% of the 2,610 delay minutes carriers reported here, and the remaining four split what is left.
- 50%Late-arriving aircraft
- 23%National Airspace System
- 22%Carrier
- 5%Extreme weather
50% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. Across 2,610 reported delay minutes here, that single category outweighs weather by 9 to one. The split is drawn from 2,610 delay minutes reported on DL 2270.
Cancellations run at 3.33%, against 1.89% nationally. That is about one flight in 30 cancelled outright. A cancelled flight is invisible in every on-time figure on this page, so the punctuality numbers above describe only the flights that actually operated.
Connections and routes
What a delay on this flight costs
Badly late arrivals are rare here: only 4.0% 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 666 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 2270 is not only a PHL to ATL flight. It also flew ATL to PHL (351 flights, 87.3% 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. 360 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.
