These figures cover 359 flights between September 2025 and August 2026. The median arrival is 10 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 13 March 2026, 1 hour 58 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).
| Date | Arrived late by | Largest filed cause |
|---|---|---|
| 13 March 2026 | 1 hour 58 minutes | Late-arriving aircraft |
| 11 October 2025 | 1 hour 54 minutes | Carrier |
| 20 January 2026 | 1 hour 53 minutes | Carrier |

Delay causes
Why DL 1496 runs late
Carrier accounts for 55% of the 2,060 delay minutes carriers reported here, and the remaining four split what is left.
- 55%Carrier
- 25%Late-arriving aircraft
- 20%National Airspace System
The largest share of delay minutes, 55%, falls under carrier control: crew scheduling, maintenance, fuelling, baggage. It accounts for 1,137 of the 2,060 delay minutes reported here. The split is drawn from 2,060 delay minutes reported on DL 1496.
Cancellations are rare at 0.56%, 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 3.4% 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 507 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 359 flights under DL 1496 in the data flew SLC to PHX. 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. 359 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 1496
For a booking, DL 1496 has one of the better records a US domestic flight can show: 87.1% on time and 0.56% cancelled. That is a base rate, not a promise about any single day.
