Across the year
DL 1356 quarter by quarter

The worst days
Worst days for DL 1356
The latest arrival of the period was on 4 September 2025, 9 hours 5 minutes behind schedule; most of its delay minutes were filed as carrier-caused (crew, maintenance, fuelling, baggage). The same cause led on three of the five worst days.
| Date | Arrived late by | Largest filed cause |
|---|---|---|
| 4 September 2025 | 9 hours 5 minutes | Carrier |
| 12 June 2026 | 4 hours 54 minutes | Late-arriving aircraft |
| 9 August 2026 | 3 hours 32 minutes | Carrier |
| 29 October 2025 | 3 hours 7 minutes | Carrier |

Delay causes
Why DL 1356 runs late
Carrier accounts for 52% of the 5,252 delay minutes carriers reported here, and the remaining four split what is left.
- 52%Carrier
- 33%Late-arriving aircraft
- 15%National Airspace System
- 0%Extreme weather
The largest share of delay minutes, 52%, falls under carrier control: crew scheduling, maintenance, fuelling, baggage. It accounts for 2,716 of the 5,252 delay minutes reported here. The split is drawn from 5,252 delay minutes reported on DL 1356.
Cancellations are rare at 0.70%, 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
11.7% 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 626 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 three other city pairs in the data, including MSP to PDX (19), LAS to LAX (16) and LAX to LAS (16), but none flew often enough under DL 1356 to report a rate for. Carriers move flight numbers between routes, so the figures on this page apply to MSP to CMH only.
One caution: this is a thin sample. 286 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
