Historical statistics for July 2025 to June 2026, not live status. For today’s DL 2070, check with Delta Air Lines.
DL 2070 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 9 points better than the national rate of 77.6%. When something does go wrong the average delay runs roughly 35 minutes. That rests on 365 flights, with a median arrival 8 minutes early.
Set against the rest of the country, DL 2070's record is 9 points better than the US average of 77.6%. That gap is worth roughly 94 fewer late arrivals for every thousand flights.

These figures cover 365 flights between July 2025 and June 2026. The median arrival is 8 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 2070 flies
DL 2070 flies SLC to CLT without a single fixed slot. Its most common scheduled departure was 10:25, used on 89 of 365 flights, with 10:30 (86 flights) and 10:08 (38 flights) next. Carriers retime flights through the season, so the rates here blend slightly different positions in the aircraft's day.
- Departs 10:2589 flights24.4%
- Departs 10:3086 flights23.6%
- Departs 10:0838 flights10.4%
Scale runs 0% to 100%. Rows with fewer than 30 flights show a dash.
Share of scheduled departures at each local time. Times used on fewer than one flight in ten are not listed.
A 10:25 departure sits in the 8am–11am window. Across every US flight scheduled in that window the on-time rate is 84.1%, and DL 2070 runs 3 points better at 87.0%. 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 2070 next to SLC to CLT
Every carrier on SLC to CLT combined arrived on time 84.3% of the time across 921 flights, so DL 2070 is 3 points ahead of it. Across its whole network Delta Air Lines managed 81.6%, which this flight beats by 5 points.

Across the year
DL 2070 quarter by quarter
Quarter by quarter DL 2070 held fairly steady: 80.4% in Jul–Sep 2025, 90.2% in Oct–Dec 2025, 89.7% in Jan–Mar 2026 and 87.8% in Apr–Jun 2026. A spread of 10 points is about what a sample of this size moves on its own, so the annual figure is a fair summary.
- Jul–Sep 202592 flights80.4%
- Oct–Dec 202592 flights90.2%
- Jan–Mar 202690 flights89.7%
- Apr–Jun 202691 flights87.8%
Scale runs 70% to 95%. Rows with fewer than 30 flights show a dash.
By weekday, DL 2070 did best on Wednesday at 94.2% on time and worst on Friday at 78.8%. Each day rests on about 52 flights, so a gap of 15 points is worth noticing but could still narrow in another year.
Delay causes
Why DL 2070 runs late
Carriers report a reason for every delay minute they cause, in five DOT categories. The split below is by minutes, not by number of flights, so a handful of very long weather delays weighs as much as many short ones. It covers 1,559 reported delay minutes.
- 38%Carrier
- 35%National Airspace System
- 27%Late-arriving aircraft
The largest share of delay minutes, 38%, 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 586 of the 1,559 delay minutes reported here. The split is drawn from 1,559 delay minutes reported on DL 2070.
Cancellations sit at 1.10% against a national 1.81%, which is ordinary. Diversions add another 0.00%.
Connections and routes
What a delay on this flight costs
Badly late arrivals are rare here: only 1.9% 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.
At 1,727 miles this is transcontinental flying, and long routes get a quiet structural advantage. Scheduled block time on a flight this length carries more padding in absolute minutes, so a twenty-minute late departure often still becomes an on-time arrival. Read the on-time rate here as slightly flattering next to a short-haul route with the same operational quality.
DL 2070 is not only a SLC to CLT flight. It also flew CLT to SLC (365 flights, 83.4% 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.

Booking DL 2070
