|---|---|---|
| 9 July 2026 | 4 hours 46 minutes | Carrier |
| 8 November 2025 | 4 hours 34 minutes | Carrier |

Delay causes
Why DL 2683 runs late
Carrier accounts for 49% of the 6,377 delay minutes carriers reported here, and the remaining four split what is left.
- 49%Carrier
- 34%Late-arriving aircraft
- 14%National Airspace System
- 2%Extreme weather
34% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. Across 6,377 reported delay minutes here, that single category outweighs weather by 14 to one. The split is drawn from 6,377 delay minutes reported on DL 2683.
Cancellations sit at 1.37% against a national 1.89%, which is ordinary. Diversions add another 0.00%.
Connections and routes
What a delay on this flight costs
11.1% 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 1,034 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 364 flights under DL 2683 in the data flew MSP to IAH. 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. 364 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.
