These figures cover 365 flights between September 2025 and August 2026. The median arrival is 6 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.

Across the year
DL 2070 quarter by quarter
DL 2070 did not run the same all year. Its best quarter was Jan–Mar 2026 at 89.7% on time and its weakest Jul–Sep 2026 at 75.4%, a swing of 14 points on roughly 73 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 2070 did best on Wednesday at 90.4% on time and worst on Sunday at 71.4%. Each day rests on about 52 flights, so a gap of 19 points is worth noticing but could still narrow in another year.
Arrival by arrival
How late DL 2070 runs when it is late
DL 2070 often beats the schedule: 100 of 360 completed flights, 28%, arrived 15 minutes or more early. Most of the lateness is short. 30 of the 60 late arrivals were under half an hour behind, and 15 reached an hour or more.

Share of 360 completed flights by arrival against schedule.
15 of 56 late departures made up the time and arrived on time, 27% of them. In the other direction, 19 flights left on time yet arrived 15 minutes late or more, so that delay built up after pushback: in the air, in a holding pattern or on the ground at SLC.
The worst days
Worst days for DL 2070
The latest arrival of the period was on 23 July 2026, 16 hours behind schedule; most of its delay minutes were filed as carrier-caused (crew, maintenance, fuelling, baggage). The same cause led on three of the five worst days.
| Date | Arrived late by | Largest filed cause |
|---|---|---|
| 23 July 2026 | 16 hours | Carrier |
| 22 August 2026 | 1 hour 47 minutes | Carrier |
| 27 June 2026 | 1 hour 22 minutes | Extreme weather |
| 28 February 2026 | 1 hour 20 minutes | Carrier |
| 27 October 2025 | 1 hour 17 minutes | Late-arriving aircraft |
Delay causes
Why DL 2070 runs late
Carrier accounts for 49% of the 3,256 delay minutes carriers reported here, and the remaining four split what is left.
- 49%Carrier
- 25%National Airspace System
- 21%Late-arriving aircraft
- 5%Extreme weather
The largest share of delay minutes, 49%, falls under carrier control: crew scheduling, maintenance, fuelling, baggage. It accounts for 1,600 of the 3,256 delay minutes reported here. The split is drawn from 3,256 delay minutes reported on DL 2070.
Cancellations sit at 1.37% against a national 1.89%, 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 4.2% land an hour or more behind schedule, against 8.3% 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 CLT to SLC flight. It also flew SLC to CLT (365 flights, 85.3% 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. 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.
