The latest arrival of the period was on 13 October 2025, 3 hours 43 minutes behind schedule; most of its delay minutes were filed as a late-arriving aircraft. The same cause led on three of the five worst days.
| Date | Arrived late by | Largest filed cause |
|---|---|---|
| 13 October 2025 | 3 hours 43 minutes | Late-arriving aircraft |
| 14 October 2025 | 3 hours 37 minutes | Late-arriving aircraft |
| 25 September 2025 | 3 hours 25 minutes | Late-arriving aircraft |

Delay causes
Why DL 2234 runs late
Late-arriving aircraft accounts for 56% of the 6,954 delay minutes carriers reported here, and the remaining four split what is left.
- 56%Late-arriving aircraft
- 33%Carrier
- 10%National Airspace System
56% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. Across 6,954 reported delay minutes here, that single category outweighs weather by 56 to one. The split is drawn from 6,954 delay minutes reported on DL 2234.
Cancellations are rare at 0.35%, 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
16.2% of arrivals land a full hour or more behind schedule, against 8.3% nationally. Ninety minutes is the honest minimum for a connection here, and two hours if the onward flight is on a separate ticket.
The 1,185 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.
The same number turns up on one other city pair in the data, including ATL to JAN (1), but none flew often enough under DL 2234 to report a rate for. Carriers move flight numbers between routes, so the figures on this page apply to BOS to TPA only.
One caution: this is a thin sample. 285 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 2234
For a booking, DL 2234 is a flight to put a long connection behind. 16.2% of its completed flights arrived an hour or more late, which a short layover will not absorb. If the onward flight is on a separate ticket, the risk sits with you.
