These figures cover 324 flights between September 2025 and August 2026. The median arrival is 14 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 latest arrival of the period was on 5 December 2025, 14 hours 13 minutes behind schedule; most of its delay minutes were filed as carrier-caused (crew, maintenance, fuelling, baggage). The same cause led on five of the five worst days.
| Date | Arrived late by | Largest filed cause |
|---|---|---|
| 5 December 2025 | 14 hours 13 minutes | Carrier |
| 30 September 2025 | 6 hours 56 minutes | Carrier |

Delay causes
Why DL 2906 runs late
Carrier accounts for 94% of the 2,092 delay minutes carriers reported here, and the remaining four split what is left.
- 94%Carrier
- 5%National Airspace System
- 2%Late-arriving aircraft
The largest share of delay minutes, 94%, falls under carrier control: crew scheduling, maintenance, fuelling, baggage. It accounts for 1,958 of the 2,092 delay minutes reported here. The split is drawn from 2,092 delay minutes reported on DL 2906.
Cancellations are rare at 0.31%, 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 2.8% 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 590 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 324 flights under DL 2906 in the data flew LAX to SLC. 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. 324 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 2906
For a booking, DL 2906 has one of the better records a US domestic flight can show: 95.4% on time and 0.31% cancelled. That is a base rate, not a promise about any single day.
