These figures cover 365 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.

| 4 January 2026 | 8 hours 25 minutes | Carrier |
| 7 October 2025 | 6 hours 54 minutes | Carrier |
| 30 July 2026 | 6 hours | Late-arriving aircraft |

Delay causes
Why DL 1587 runs late
Late-arriving aircraft accounts for 48% of the 4,994 delay minutes carriers reported here, and the remaining four split what is left.
- 48%Late-arriving aircraft
- 31%Carrier
- 20%National Airspace System
- 1%Extreme weather
48% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. Across 4,994 reported delay minutes here, that single category outweighs weather by 37 to one. The split is drawn from 4,994 delay minutes reported on DL 1587.
Cancellations sit at 1.92% against a national 1.89%, which is ordinary. Diversions add another 0.27%.
Connections and routes
What a delay on this flight costs
7.3% 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.
DL 1587 is not only a TPA to ATL flight. It also flew ATL to TPA (365 flights, 79.8% 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. 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.
