Historical statistics for July 2025 to June 2026, not live status. For today’s DL 1452, check with Delta Air Lines.

DL 1452 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 an hour and a half. That rests on 322 flights, with a median arrival 12 minutes early.

Set against the rest of the country, DL 1452's record is 9 points better than the US average of 77.6%. That gap is worth roughly 92 fewer late arrivals for every thousand flights.

These figures cover 322 flights between July 2025 and June 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.

Schedule

When DL 1452 flies

DL 1452 flies GEG to SLC without a single fixed slot. Its most common scheduled departure was 13:15, used on 79 of 322 flights, with 13:10 (68 flights) and 13:00 (57 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 13:15 departure sits in the 11am–2pm window. Across every US flight scheduled in that window the on-time rate is 78.8%, and DL 1452 runs 8 points better at 86.8%. Midday slots inherit some of the morning's delays without yet carrying the full weight of the evening's.

Across the year

DL 1452 quarter by quarter

DL 1452 did not run the same all year. Its best quarter was Oct–Dec 2025 at 92.4% on time and its weakest Jul–Sep 2025 at 82.4%, a swing of 10 points on roughly 81 flights a quarter. The twelve-month rate averages over that, so if you are flying in a weak quarter the quarter's own figure is the better guide.

By weekday, DL 1452 ranged from 82.2% on Sunday to 93.5% on Thursday. With about 46 flights behind each day, a spread of 11 points is inside normal variation, so the day you fly is not worth changing for this flight.

Delay causes

Why DL 1452 runs late

One category carries most of the weight here. Carrier accounts for 58% of the 4,117 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
58%
Late-arriving aircraft
38%
National Airspace System
4%
Extreme weather
0%

38% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. That is a cascade, and cascades start small and grow through the day. Across 4,117 reported delay minutes here, that single category outweighs weather by 38 to one. It is the strongest argument for booking the first departure of the morning, when the aircraft has been sitting at the gate overnight with nothing to inherit. The split is drawn from 4,117 delay minutes reported on DL 1452.

Cancellations are rare at 0.62%, 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 4.4% 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 546 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.

DL 1452 is not only a GEG to SLC flight. It also flew SLC to GEG (322 flights, 84.3% on time) often enough to be scored on its own. Airlines attach one number to several legs of an aircraft's day, and each leg keeps its own record here, so check which city pair is on your booking before reading a rate.

One caution: this is a thin sample. 322 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 1452

For a booking, DL 1452 has one of the better records a US domestic flight can show: 86.8% on time and 0.62% cancelled. That is a base rate, not a promise about any single day.
