Historical statistics for July 2025 to June 2026, not live status. For today’s DL 1496, check with Delta Air Lines.

DL 1496 earns an A+. More than four flights in five arrive inside the 15-minute window the DOT uses to define an on-time arrival, which puts it 9 points better than the national rate of 77.6%. When something does go wrong the average delay runs roughly 45 minutes. That rests on 359 flights, with a median arrival 10 minutes early.

Set against the rest of the country, DL 1496's record is 9 points better than the US average of 77.6%. That gap is worth roughly 87 fewer late arrivals for every thousand flights.

These figures cover 359 flights between July 2025 and June 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.

Schedule

When DL 1496 flies

DL 1496 flies SLC to PHX without a single fixed slot. Its most common scheduled departure was 22:45, used on 74 of 359 flights, with 22:50 (64 flights) and 22:55 (54 flights) next. Carriers retime flights through the season, so the rates here blend slightly different positions in the aircraft's day.

Share of scheduled departures at each local time. Times used on fewer than one flight in ten are not listed.

A 22:45 departure sits in the 8pm–5am window. Across every US flight scheduled in that window the on-time rate is 70.5%, and DL 1496 runs 16 points better at 86.3%. By that time of day most aircraft have flown several legs already, and whatever went wrong earlier is still in the schedule.

Against the route

DL 1496 next to SLC to PHX

Across the year

DL 1496 quarter by quarter

Quarter by quarter DL 1496 held fairly steady: 82.4% in Jul–Sep 2025, 90.0% in Oct–Dec 2025, 81.6% in Jan–Mar 2026 and 91.0% in Apr–Jun 2026. A spread of 9 points is about what a sample of this size moves on its own, so the annual figure is a fair summary.

Jul–Sep 202592 flights82.4%
Oct–Dec 202591 flights90.0%
Jan–Mar 202687 flights81.6%

Scale runs 75% to 95%. Rows with fewer than 30 flights show a dash.

By weekday, DL 1496 did best on Tuesday at 92.5% on time and worst on Sunday at 76.5%. Each day rests on about 51 flights, so a gap of 16 points is worth noticing but could still narrow in another year.

Delay causes

Why DL 1496 runs late

One category carries most of the weight here. Carrier accounts for 60% of the 2,283 delay minutes carriers reported, and the remaining four split what is left. The split is by minutes rather than by flights, so a few very long delays count for as much as many short ones.

Carrier
60%
Late-arriving aircraft
27%
National Airspace System
12%

The largest share of delay minutes, 60%, falls under carrier control: crew scheduling, maintenance, fuelling, baggage. Unlike weather, that is a management outcome, and it is the category where the gap between two carriers on the same schedule is genuinely earned. It accounts for 1,380 of the 2,283 delay minutes reported here. The split is drawn from 2,283 delay minutes reported on DL 1496.

Cancellations are rare at 0.56%, below the national 1.81% 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 3.1% land an hour or more behind schedule, against 8.1% 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. It is also long enough that the aircraft usually flies three or four legs a day rather than six, which slows how fast delay compounds.

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: 86.3% on time and 0.56% cancelled. That is a base rate, not a promise about any single day.
