These figures cover 365 flights between September 2025 and August 2026. The median arrival is 11 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 1595
The latest arrival of the period was on 29 December 2025, 11 hours 19 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 |
|---|---|---|
| 29 December 2025 | 11 hours 19 minutes | Carrier |
| 24 February 2026 | 6 hours 44 minutes | Late-arriving aircraft |
| 17 February 2026 | 4 hours 43 minutes | Late-arriving aircraft |
| 14 October 2025 | 4 hours 25 minutes | Carrier |
| 21 December 2025 | 4 hours 13 minutes | Carrier |
Delay causes
Why DL 1595 runs late
Late-arriving aircraft accounts for 45% of the 4,090 delay minutes carriers reported here, and the remaining four split what is left.
- 45%Late-arriving aircraft
- 44%Carrier
- 6%Extreme weather
- 5%National Airspace System
45% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. Across 4,090 reported delay minutes here, that single category outweighs weather by 8 to one. The split is drawn from 4,090 delay minutes reported on DL 1595.
Cancellations are rare at 0.27%, 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
5.0% 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.
DL 1595 is not only a RNO to SLC flight. It also flew SLC to RNO (365 flights, 87.1% on time) often enough to be scored on its own. Airlines attach one number to several legs of an aircraft's day, and each leg keeps its own record here, so check which city pair is on your booking before reading a rate.
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.
| Also flown as | Flights | On time | Avg delay | Cancelled | Grade |
