These figures cover 365 flights between September 2025 and August 2026. The median arrival is 17 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.

Across the year

DL 1360 quarter by quarter

Delay causes

Why DL 1360 runs late

Carrier accounts for 70% of the 2,163 delay minutes carriers reported here, and the remaining four split what is left.

Carrier
70%
National Airspace System
20%
Late-arriving aircraft
10%

The largest share of delay minutes, 70%, falls under carrier control: crew scheduling, maintenance, fuelling, baggage. It accounts for 1,512 of the 2,163 delay minutes reported here. The split is drawn from 2,163 delay minutes reported on DL 1360.

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 2.7% 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 1360 in the data flew BIL 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 1360

For a booking, DL 1360 has one of the better records a US domestic flight can show: 94.0% on time and 0.27% cancelled. That is a base rate, not a promise about any single day.
