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.

Schedule
When DL 2800 flies
DL 2800 flies SLC to DFW without a single fixed slot. Its most common scheduled departure was 09:50, used on 86 of 365 flights, with 10:00 (74 flights) next.
- Departs 09:5086 flights23.6%
- Departs 10:0074 flights20.3%
Scale runs 0% to 100%.
Share of scheduled departures at each local time. Times used on fewer than one flight in ten are not listed.
A 09:50 departure sits in the 8am–11am window. Across every US flight scheduled in that window the on-time rate is 83.9%, and DL 2800 runs level with that at 83.6%. 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 2800 quarter by quarter
DL 2800 did not run the same all year. Its best quarter was Jan–Mar 2026 at 90.9% on time and its weakest Oct–Dec 2025 at 78.3%, a swing of 13 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.

By weekday, DL 2800 did best on Wednesday at 94.2% on time and worst on Tuesday at 76.5%. Each day rests on about 52 flights, so a gap of 18 points is worth noticing but could still narrow in another year.

The worst days
Worst days for DL 2800
The latest arrival of the period was on 20 November 2025, 3 hours 32 minutes behind schedule; most of its delay minutes were filed as national airspace system delay. The five worst days are spread across November, January, December and May, with no single month standing out.
| Date | Arrived late by | Largest filed cause |
|---|---|---|
| 20 November 2025 | 3 hours 32 minutes | National Airspace System |
| 11 January 2026 | 2 hours 39 minutes | Carrier |
| 13 December 2025 | 2 hours 4 minutes | Carrier |
| 11 May 2026 | 1 hour 47 minutes | Late-arriving aircraft |
| 15 December 2025 | 1 hour 21 minutes | Late-arriving aircraft |
Delay causes
Why DL 2800 runs late
Carrier accounts for 51% of the 2,485 delay minutes carriers reported here, and the remaining four split what is left.
- 51%Carrier
- 26%National Airspace System
- 21%Late-arriving aircraft
- 1%Extreme weather
The largest share of delay minutes, 51%, falls under carrier control: crew scheduling, maintenance, fuelling, baggage. It accounts for 1,279 of the 2,485 delay minutes reported here. The split is drawn from 2,485 delay minutes reported on DL 2800.
Cancellations are rare at 0.55%, below the national 1.89% 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 2.5% 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.
The 989 miles between these two airports put this in the middle of the US network, around two and a half to three hours of block time. That is enough cruise to absorb a ten-minute late pushback and not enough to absorb thirty.
The same number turns up on one other city pair in the data, including DFW to SLC (222), but none flew often enough under DL 2800 to report a rate for. Carriers move flight numbers between routes, so the figures on this page apply to SLC to DFW only.
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 2800
For a booking, read DL 2800 as 83.6% on time with 0.55% cancelled over 365 flights. Those are rates from the past twelve months, not a forecast for any particular day.
