These figures cover 271 flights between September 2025 and August 2026. The median arrival is 11 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.

Delay causes
Why DL 2605 runs late
Late-arriving aircraft accounts for 49% of the 1,407 delay minutes carriers reported here, and the remaining four split what is left.
- 49%Late-arriving aircraft
- 31%National Airspace System
- 18%Carrier
- 1%Extreme weather
49% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. Across 1,407 reported delay minutes here, that single category outweighs weather by 33 to one. The split is drawn from 1,407 delay minutes reported on DL 2605.
Cancellations sit at 1.11% against a national 1.89%, which is ordinary. Diversions add another 0.00%.
Connections and routes
What a delay on this flight costs
Badly late arrivals are rare here: only 3.4% 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.
DL 2605 is not only a TPA to ATL flight. It also flew ATL to TPA (262 flights, 92.2% 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. 271 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.
