These figures cover 331 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.

| 16 March 2026 | 5 hours 2 minutes | Extreme weather |
| 2 February 2026 | 2 hours 58 minutes | Extreme weather |

Delay causes
Why DL 1352 runs late
Carrier accounts for 48% of the 1,507 delay minutes carriers reported here, and the remaining four split what is left.
- 48%Carrier
- 33%Extreme weather
- 19%National Airspace System
Extreme weather accounts for 33% of delay minutes, well above the single-digit share typical across the system. Weather delays are lumpy: they arrive as whole bad days rather than as a steady drag, so the quarterly figures above are the more useful view of the risk. The national share is 6%, so this operation carries roughly 5.4 times the usual weather exposure. The split is drawn from 1,507 delay minutes reported on DL 1352.
Cancellations sit at 1.21% against a national 1.89%, which is ordinary. Diversions add another 0.30%.
Connections and routes
What a delay on this flight costs
Badly late arrivals are rare here: only 2.1% 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 545 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.
Every one of the 331 flights under DL 1352 in the data flew PBI to ATL. The number was not reused on any other city pair, which makes this a clean record of one route.
One caution: this is a thin sample. 331 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.
What to do with this
Booking DL 1352
For a booking, DL 1352 has one of the better records a US domestic flight can show: 92.9% on time and 1.21% cancelled. That is a base rate, not a promise about any single day.
