These figures cover 302 flights between September 2025 and August 2026. The median arrival is 4 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.

The worst days
Worst days for DL 2149
The latest arrival of the period was on 7 August 2026, 3 hours 59 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 |
|---|---|---|
| 7 August 2026 | 3 hours 59 minutes | Late-arriving aircraft |
| 10 September 2025 | 2 hours 59 minutes | Carrier |
| 17 April 2026 | 2 hours 58 minutes | Late-arriving aircraft |
| 27 April 2026 | 2 hours 44 minutes | Extreme weather |
| 27 July 2026 | 2 hours 39 minutes | Late-arriving aircraft |
Delay causes
Why DL 2149 runs late
Late-arriving aircraft accounts for 56% of the 3,757 delay minutes carriers reported here, and the remaining four split what is left.
- 56%Late-arriving aircraft
- 26%Carrier
- 13%National Airspace System
- 5%Extreme weather
56% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. Across 3,757 reported delay minutes here, that single category outweighs weather by 11 to one. The split is drawn from 3,757 delay minutes reported on DL 2149.
Cancellations are rare at 0.66%, 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
7.3% 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 about an hour, which a normal layover absorbs.
The 1,450 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 SLC to CVG (55), but none flew often enough under DL 2149 to report a rate for. Carriers move flight numbers between routes, so the figures on this page apply to CVG to SLC only.
One caution: this is a thin sample. 302 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.
