These figures cover 344 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.

The latest arrival of the period was on 7 December 2025, 3 hours 55 minutes behind schedule; most of its delay minutes were filed as a late-arriving aircraft. The five worst days are spread across December, July, May and March, with no single month standing out.
| Date | Arrived late by | Largest filed cause |
|---|---|---|
| 7 December 2025 | 3 hours 55 minutes | Late-arriving aircraft |
| 24 July 2026 | 2 hours 48 minutes | Late-arriving aircraft |
| 14 December 2025 | 2 hours 34 minutes | National Airspace System |

Delay causes
Why DL 2545 runs late
Carrier accounts for 51% of the 2,288 delay minutes carriers reported here, and the remaining four split what is left.
- 51%Carrier
- 24%National Airspace System
- 23%Late-arriving aircraft
- 2%Extreme weather
The largest share of delay minutes, 51%, falls under carrier control: crew scheduling, maintenance, fuelling, baggage. It accounts for 1,160 of the 2,288 delay minutes reported here. The split is drawn from 2,288 delay minutes reported on DL 2545.
Cancellations are rare at 0.87%, below the national 1.89% and low enough to earn the plus on the grade. Roughly one flight in 100 is called off; the risk here is arriving late, not not arriving.
Connections and routes
What a delay on this flight costs
Badly late arrivals are rare here: only 3.5% 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 554 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 2545 is not only a ATL to CLE flight. It also flew CLE to ATL (343 flights, 85.5% 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. 344 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.
