DL 698 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 11 points better than the national rate of 77.6%. When something does go wrong the average delay runs about an hour. That rests on 365 flights, with a median arrival 7 minutes early.

These figures cover 365 flights between July 2025 and June 2026. The median arrival is 7 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 698 flies

DL 698 flies DTW to SLC without a single fixed slot. Its most common scheduled departure was 08:00, used on 125 of 365 flights, with 08:20 (62 flights) and 08:25 (59 flights) next. Carriers retime flights through the season, so the rates here blend slightly different positions in the aircraft's day.

Share of scheduled departures at each local time. Times used on fewer than one flight in ten are not listed.

A 08:00 departure sits in the 8am–11am window. Across every US flight scheduled in that window the on-time rate is 84.1%, and DL 698 runs 5 points better at 89.0%. 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 698 quarter by quarter

DL 698 did not run the same all year. Its best quarter was Apr–Jun 2026 at 94.4% on time and its weakest Jan–Mar 2026 at 76.4%, a swing of 18 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.

Jul–Sep 202592 flights93.5%
Oct–Dec 202592 flights91.3%
Jan–Mar 202690 flights76.4%
Apr–Jun 202691 flights94.4%

Scale runs 70% to 100%. Rows with fewer than 30 flights show a dash.

By weekday, DL 698 ranged from 84.6% on Saturday to 94.2% on Tuesday. With about 52 flights behind each day, a spread of 10 points is inside normal variation, so the day you fly is not worth changing for this flight.

Delay causes

Why DL 698 runs late

One category carries most of the weight here. Carrier accounts for 61% of the 2,673 delay minutes carriers reported, and the remaining four split what is left. The split is by minutes rather than by flights, so a few very long delays count for as much as many short ones.

Carrier
61%
National Airspace System
20%
Late-arriving aircraft
15%
Extreme weather
5%

The largest share of delay minutes, 61%, 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 1,622 of the 2,673 delay minutes reported here. The split is drawn from 2,673 delay minutes reported on DL 698.

Cancellations are rare at 0.55%, below the national 1.81% 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 2.8% 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.

The 1,481 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. It is also long enough that the aircraft usually flies three or four legs a day rather than six, which slows how fast delay compounds.

Every one of the 365 flights under DL 698 in the data flew DTW to SLC. The number was not reused on any other city pair, which makes this a clean record of one route.

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 698

For a booking, DL 698 has one of the better records a US domestic flight can show: 89.0% on time and 0.55% cancelled. That is a base rate, not a promise about any single day.
