These figures cover 322 flights between September 2025 and August 2026. The median arrival is 13 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 1452
The latest arrival of the period was on 5 November 2025, 10 hours 26 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 |
|---|---|---|
| 5 November 2025 | 10 hours 26 minutes | Carrier |
| 7 June 2026 | 8 hours 38 minutes | Carrier |
| 7 July 2026 | 7 hours 51 minutes | Carrier |
| 22 June 2026 | 5 hours 31 minutes | Carrier |
| 1 February 2026 | 3 hours 51 minutes | Late-arriving aircraft |
Delay causes
Why DL 1452 runs late
Carrier accounts for 60% of the 4,028 delay minutes carriers reported here, and the remaining four split what is left.
- 60%Carrier
- 36%Late-arriving aircraft
- 4%National Airspace System
- 1%Extreme weather
36% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. Across 4,028 reported delay minutes here, that single category outweighs weather by 36 to one. The split is drawn from 4,028 delay minutes reported on DL 1452.
Cancellations are rare at 0.62%, 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
Badly late arrivals are rare here: only 4.1% 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 546 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.
DL 1452 is not only a GEG to SLC flight. It also flew SLC to GEG (322 flights, 81.8% 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. 322 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.
