Historical statistics for July 2025 to June 2026, not live status. For today’s DL 1650, check with Delta Air Lines.

DL 1650 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 an hour and a half. That rests on 365 flights, with a median arrival 10 minutes early.

Set against the rest of the country, DL 1650's record is 13 points better than the US average of 77.6%. That gap is worth roughly 128 fewer late arrivals for every thousand flights.

These figures cover 365 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 1650 flies

DL 1650 flies RNO to SLC without a single fixed slot. Its most common scheduled departure was 06:00, used on 278 of 365 flights, with 05:30 (62 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 06:00 departure sits in the 5am–8am window. Across every US flight scheduled in that window the on-time rate is 89.3%, and DL 1650 runs level with that at 90.4%. Early departures usually start with an aircraft that has not flown yet that day, which is most of why the window does well.

Against the route

DL 1650 next to RNO to SLC

Every carrier on RNO to SLC combined arrived on time 90.1% of the time across 1,195 flights, so DL 1650 is about level with it. Delta flew 730 flights on the same city pair under all its flight numbers, including this one, and those ran 90.5% on time. Across its whole network Delta Air Lines managed 81.6%, which this flight beats by 9 points.

Across the year

DL 1650 quarter by quarter

DL 1650 did not run the same all year. Its best quarter was Apr–Jun 2026 at 95.6% on time and its weakest Jan–Mar 2026 at 84.4%, a swing of 11 points on roughly 91 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.

Jul–Sep 202592 flights94.6%
Oct–Dec 202592 flights86.8%
Jan–Mar 202690 flights84.4%

Scale runs 75% to 100%. Rows with fewer than 30 flights show a dash.

By weekday, DL 1650 did best on Monday at 100.0% on time and worst on Thursday at 80.8%. Each day rests on about 52 flights, so a gap of 19 points is worth noticing but could still narrow in another year.

Delay causes

Why DL 1650 runs late

One category carries most of the weight here. Carrier accounts for 63% of the 2,909 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
63%
National Airspace System
16%
Late-arriving aircraft
13%
Extreme weather
8%

The largest share of delay minutes, 63%, 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 1,822 of the 2,909 delay minutes reported here. The split is drawn from 2,909 delay minutes reported on DL 1650.

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 3.8% 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.

Every one of the 365 flights under DL 1650 in the data flew RNO 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 1650

For a booking, DL 1650 has one of the better records a US domestic flight can show: 90.4% on time and 0.27% cancelled. That is a base rate, not a promise about any single day.
