DL 1595 earns an A+. Close to nine flights in ten arrive inside the 15-minute window the DOT uses to define an on-time arrival, which puts it 13 points better than the national rate of 77.6%. When something does go wrong the average delay runs close to two hours. That rests on 365 flights, with a median arrival 12 minutes early.

Set against the rest of the country, DL 1595's record is 13 points better than the US average of 77.6%. That gap is worth roughly 130 fewer late arrivals for every thousand flights.

These figures cover 365 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 1595 flies

DL 1595 flies RNO to SLC without a single fixed slot. Its most common scheduled departure was 13:15, used on 110 of 365 flights, with 13:30 (103 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 1595 runs 12 points better at 90.6%. Midday slots inherit some of the morning's delays without yet carrying the full weight of the evening's.

Across the year

DL 1595 quarter by quarter

Quarter by quarter DL 1595 held fairly steady: 92.4% in Jul–Sep 2025, 85.9% in Oct–Dec 2025, 91.1% in Jan–Mar 2026 and 93.3% in Apr–Jun 2026. A spread of 7 points is about what a sample of this size moves on its own, so the annual figure is a fair summary.

Jul–Sep 202592 flights92.4%
Oct–Dec 202592 flights85.9%
Jan–Mar 202690 flights91.1%

By weekday, DL 1595 ranged from 86.5% on Tuesday to 96.1% on Friday. With about 52 flights behind each day, a spread of 10 points is inside normal variation, so the day you fly is not worth changing for this flight.

Delay causes

Why DL 1595 runs late

One category carries most of the weight here. Carrier accounts for 50% of the 3,932 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
50%
Late-arriving aircraft
44%
National Airspace System
3%
Extreme weather
3%

44% 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 3,932 reported delay minutes here, that single category outweighs weather by 17 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 3,932 delay minutes reported on DL 1595.

Cancellations are rare at 0.27%, 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 4.7% 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.

DL 1595 is not only a RNO to SLC flight. It also flew SLC to RNO (365 flights, 87.1% 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. 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.
