These figures cover 365 flights between September 2025 and August 2026. The median arrival is 12 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.

A 06:00 departure sits in the 5am–8am window. Across every US flight scheduled in that window the on-time rate is 89.3%, and DL 2674 runs 6 points better at 95.1%. Early departures usually start with an aircraft that has not flown yet that day, which is most of why the window does well.

The latest arrival of the period was on 19 July 2026, 11 hours 51 minutes behind schedule; most of its delay minutes were filed as a late-arriving aircraft. On three of the five worst days the largest share was filed as carrier-caused (crew, maintenance, fuelling, baggage).

Delay causes

Why DL 2674 runs late

Late-arriving aircraft accounts for 48% of the 1,899 delay minutes carriers reported here, and the remaining four split what is left.

Late-arriving aircraft
48%
Carrier
45%
National Airspace System
7%

48% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. Across 1,899 reported delay minutes here, that single category outweighs weather by 48 to one. The split is drawn from 1,899 delay minutes reported on DL 2674.

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

Badly late arrivals are rare here: only 1.6% 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.

Every one of the 365 flights under DL 2674 in the data flew LAS 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. 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.

What to do with this

Booking DL 2674

For a booking, DL 2674 has one of the better records a US domestic flight can show: 95.1% on time and 0.27% cancelled. That is a base rate, not a promise about any single day.
