Historical statistics for September 2025 to August 2026, not live status. For today’s DL 2033, check with Delta Air Lines.
DL 2033 lands a B−, 4 points better than the national rate of 77.3%. About one flight in five arrives 15 minutes late or worse, and those flights are late by about an hour on average. That rests on 255 flights, with a median arrival 8 minutes early.
Set against the rest of the country, DL 2033's record is 4 points better than the US average of 77.3%. That gap is worth roughly 40 fewer late arrivals for every thousand flights.

These figures cover 255 flights between September 2025 and August 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 2033 flies
DL 2033 flies SLC to EWR without a single fixed slot. Its most common scheduled departure was 10:25, used on 51 of 255 flights, with 11:15 (28 flights) next.
- Departs 10:2551 flights20.0%

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 83.9%, and DL 2033 runs 3 points worse at 81.3%. Early departures usually start with an aircraft that has not flown yet that day, which is most of why the window does well.

Across the year
DL 2033 quarter by quarter
Quarter by quarter DL 2033 held fairly steady: 82.4% in Jan–Mar 2026, 86.7% in Apr–Jun 2026 and 76.8% in Jul–Sep 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.
- Oct–Dec 202512 flights—
- Jan–Mar 202690 flights82.4%
- Apr–Jun 202691 flights86.7%
- Jul–Sep 202662 flights76.8%
Scale runs 70% to 90%. Rows with fewer than 30 flights show a dash.
By weekday, DL 2033 did best on Wednesday at 91.4% on time and worst on Saturday at 70.6%. Each day rests on about 36 flights, so a gap of 21 points is worth noticing but could still narrow in another year.
Arrival by arrival

The worst days
Worst days for DL 2033
The latest arrival of the period was on 30 December 2025, 4 hours 45 minutes behind schedule; most of its delay minutes were filed as carrier-caused (crew, maintenance, fuelling, baggage). The five worst days are spread across December, February, July and August, with no single month standing out.
| Date | Arrived late by | Largest filed cause |
|---|---|---|
| 30 December 2025 | 4 hours 45 minutes | Carrier |
| 18 February 2026 | 3 hours 44 minutes | Extreme weather |
| 21 July 2026 | 3 hours 41 minutes | Extreme weather |
| 8 August 2026 | 2 hours 36 minutes | National Airspace System |
| 12 February 2026 | 2 hours 5 minutes | Carrier |
Delay causes
Why DL 2033 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 2,791 reported delay minutes.
- 37%National Airspace System
- 24%Carrier
- 24%Late-arriving aircraft
- 14%Extreme weather
Extreme weather accounts for 14% of delay minutes, well above the single-digit share typical across the system. Weather delays are lumpy: they arrive as whole bad days rather than as a steady drag, so the quarterly figures above are the more useful view of the risk. The national share is 6%, so this operation carries roughly 2.4 times the usual weather exposure. The split is drawn from 2,791 delay minutes reported on DL 2033.
Cancellations run at 4.31%, against 1.89% nationally. That is about one flight in 25 cancelled outright. A cancelled flight is invisible in every on-time figure on this page, so the punctuality numbers above describe only the flights that actually operated.
Connections and routes
What a delay on this flight costs
5.8% of arrivals land an hour or more late, close to the national 8.3%, so a 60 to 75 minute layover is reasonable here while anything under 45 minutes is a bet. Most delays on this route last about an hour, which a normal layover absorbs.
At 1,969 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.
The same number turns up on two other city pairs in the data, including EWR to SLC (208) and BTV to ATL (30), but none flew often enough under DL 2033 to report a rate for. Carriers move flight numbers between routes, so the figures on this page apply to SLC to EWR only.
One caution: this is a thin sample. 255 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 2033
For a booking, the cancellation rate is the figure to plan around on DL 2033: 4.31% of its 255 scheduled flights did not operate. A late arrival costs about an hour, but a cancellation costs the day, so leave a later option open.
