These figures cover 365 flights between September 2025 and August 2026. The median arrival is 12 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.

| Date | Arrived late by | Largest filed cause |
|---|---|---|
| 20 May 2026 | 4 hours 26 minutes | Carrier |
| 19 April 2026 | 4 hours 24 minutes | Carrier |

Delay causes
Why DL 2183 runs late
Carrier accounts for 64% of the 2,131 delay minutes carriers reported here, and the remaining four split what is left.
- 64%Carrier
- 25%Extreme weather
- 10%National Airspace System
Extreme weather accounts for 25% 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 4.2 times the usual weather exposure. The split is drawn from 2,131 delay minutes reported on DL 2183.
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
Badly late arrivals are rare here: only 3.1% 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 986 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 365 flights under DL 2183 in the data flew DFW to DTW. 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. 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.
What to do with this
Booking DL 2183
For a booking, DL 2183 has one of the better records a US domestic flight can show: 93.3% on time and 1.37% cancelled. That is a base rate, not a promise about any single day.
