The latest arrival of the period was on 28 April 2026, 14 hours 54 minutes behind schedule; most of its delay minutes were filed as carrier-caused (crew, maintenance, fuelling, baggage). The same cause led on four of the five worst days.
| Date | Arrived late by | Largest filed cause |
|---|---|---|
| 28 April 2026 | 14 hours 54 minutes | Carrier |
| 26 January 2026 | 6 hours 28 minutes | Late-arriving aircraft |
| 17 October 2025 | 5 hours 46 minutes | Carrier |
| 22 October 2025 | 5 hours 25 minutes | Carrier |

Delay causes
Why DL 2736 runs late
Carrier accounts for 56% of the 5,972 delay minutes carriers reported here, and the remaining four split what is left.
- 56%Carrier
- 36%Late-arriving aircraft
- 5%National Airspace System
- 4%Extreme weather
36% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. Across 5,972 reported delay minutes here, that single category outweighs weather by 10 to one. The split is drawn from 5,972 delay minutes reported on DL 2736.
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
8.5% of arrivals land an hour or more late, close to the national 8.3%, so a 60 to 75 minute layover is reasonable here while anything under 45 minutes is a bet. Most delays on this route last close to two hours, which a normal layover absorbs.
The 1,149 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 284 flights under DL 2736 in the data flew AUS 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. 284 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.
