Historical statistics for July 2025 to June 2026, not live status. For today’s DL 2291, check with Delta Air Lines.

DL 2291 earns an A+. More than four flights in five arrive inside the 15-minute window the DOT uses to define an on-time arrival, which puts it 8 points better than the national rate of 77.6%. When something does go wrong the average delay runs about an hour. That rests on 315 flights, with a median arrival 10 minutes early.

Set against the rest of the country, DL 2291's record is 8 points better than the US average of 77.6%. That gap is worth roughly 84 fewer late arrivals for every thousand flights.

These figures cover 315 flights between July 2025 and June 2026. The median arrival is 10 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 2291 flies

DL 2291 flies SLC to CVG without a single fixed slot. Its most common scheduled departure was 17:30, used on 91 of 315 flights, with 17:45 (86 flights) and 17:35 (38 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 17:30 departure sits in the 5pm–8pm window. Across every US flight scheduled in that window the on-time rate is 68.2%, and DL 2291 runs 18 points better at 86.0%. By that time of day most aircraft have flown several legs already, and whatever went wrong earlier is still in the schedule.

Against the route

DL 2291 next to SLC to CVG

Across the year

DL 2291 quarter by quarter

Quarter by quarter DL 2291 held fairly steady: 85.0% in Jul–Sep 2025, 83.7% in Oct–Dec 2025, 84.5% in Jan–Mar 2026 and 90.1% in Apr–Jun 2026. A spread of 6 points is about what a sample of this size moves on its own, so the annual figure is a fair summary.

By weekday, DL 2291 did best on Wednesday at 94.9% on time and worst on Saturday at 72.5%. Each day rests on about 45 flights, so a gap of 22 points is worth noticing but could still narrow in another year.

Delay causes

Why DL 2291 runs late

One category carries most of the weight here. Carrier accounts for 58% of the 2,789 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.

Late-arriving aircraft

National Airspace System
18%
Extreme weather
1%

The largest share of delay minutes, 58%, 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 1,631 of the 2,789 delay minutes reported here. The split is drawn from 2,789 delay minutes reported on DL 2291.

Cancellations are rare at 0.00%, below the national 1.81% and low enough to earn the plus on the grade. Almost no flights are 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 4.4% 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 1,450 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 315 flights under DL 2291 in the data flew SLC to CVG. 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. 315 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 2291

For a booking, DL 2291 has one of the better records a US domestic flight can show: 86.0% on time and 0.00% cancelled. That is a base rate, not a promise about any single day.
