These figures cover 361 flights between September 2025 and August 2026. The median arrival is 12 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.

The worst days
Worst days for DL 1698
The latest arrival of the period was on 7 November 2025, 2 hours 51 minutes behind schedule; most of its delay minutes were filed as carrier-caused (crew, maintenance, fuelling, baggage). The five worst days are spread across November, October, July and December, with no single month standing out.
| Date | Arrived late by | Largest filed cause |
|---|---|---|
| 7 November 2025 | 2 hours 51 minutes | Carrier |
| 28 October 2025 | 1 hour 56 minutes | National Airspace System |

Delay causes
Why DL 1698 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 932 reported delay minutes.
- 40%National Airspace System
- 39%Carrier
- 21%Late-arriving aircraft
The largest share of delay minutes, 39%, falls under carrier control: crew scheduling, maintenance, fuelling, baggage. It accounts for 366 of the 932 delay minutes reported here. The split is drawn from 932 delay minutes reported on DL 1698.
Cancellations are rare at 0.83%, 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 0.6% 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 same number turns up on one other city pair in the data, including LAS to SLC (133), but none flew often enough under DL 1698 to report a rate for. Carriers move flight numbers between routes, so the figures on this page apply to SLC to LAS only.
One caution: this is a thin sample. 361 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 1698
For a booking, DL 1698 has one of the better records a US domestic flight can show: 93.3% on time and 0.83% cancelled. That is a base rate, not a promise about any single day.
