Historical statistics for July 2025 to June 2026, not live status. For today’s DL 2149, check with Delta Air Lines.

DL 2149 lands a B+, level with the national rate of 77.6%. Roughly one flight in five arrives 15 minutes late or worse, and those flights are late by about an hour on average. That is a workable record, not a spotless one. That rests on 295 flights, with a median arrival 4 minutes early.

These figures cover 295 flights between July 2025 and June 2026. The median arrival is 4 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 2149 flies

DL 2149 flies CVG to SLC without a single fixed slot. Its most common scheduled departure was 19:59, used on 170 of 295 flights, with 19:55 (62 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 19:59 departure sits in the 5pm–8pm window. Across every US flight scheduled in that window the on-time rate is 68.2%, and DL 2149 runs 10 points better at 78.2%. 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 2149 next to CVG to SLC

Every carrier on CVG to SLC combined arrived on time 83.7% of the time across 821 flights, so DL 2149 is 6 points behind it. Across its whole network Delta Air Lines managed 81.6%, which this flight trails by 3 points.

Across the year

DL 2149 quarter by quarter

DL 2149 did not run the same all year. Its best quarter was Apr–Jun 2026 at 83.3% on time and its weakest Jul–Sep 2025 at 72.9%, a swing of 10 points on roughly 74 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 202585 flights72.9%
Oct–Dec 202586 flights79.1%
Jan–Mar 202658 flights78.6%
Apr–Jun 202666 flights83.3%

Scale runs 65% to 90%. Rows with fewer than 30 flights show a dash.

By weekday, DL 2149 did best on Wednesday at 88.9% on time and worst on Sunday at 68.2%. Each day rests on about 42 flights, so a gap of 21 points is worth noticing but could still narrow in another year.

Delay causes

Why DL 2149 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 3,707 reported delay minutes.

Carrier
39%
Late-arriving aircraft
35%
National Airspace System
15%
Extreme weather
10%

35% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. That is a cascade, and cascades start small and grow through the day. Across 3,707 reported delay minutes here, that single category outweighs weather by 4 to one. It is the strongest argument for booking the first departure of the morning, when the aircraft has been sitting at the gate overnight with nothing to inherit. The split is drawn from 3,707 delay minutes reported on DL 2149.

Cancellations are rare at 0.68%, 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

7.2% of arrivals land an hour or more late, close to the national 8.1%. That is the figure that decides a connection, and it says 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.

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.

The same number turns up on one other city pair in the data, including SLC to CVG (61), but none flew often enough under DL 2149 to report a rate for. Carriers move flight numbers between routes, so the figures on this page apply to CVG to SLC only.

One caution: this is a thin sample. 295 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 2149

For a booking, DL 2149 is one of the weaker ways to fly CVG to SLC: 6 points below the route as a whole. If the schedule allows, compare it with the other departures listed on the route page before settling on this one.
