Historical statistics for July 2025 to June 2026, not live status. For today’s DL 2145, check with Delta Air Lines.

DL 2145 sits in the middle of the pack with a C+. About seven flights in ten arrive on time by the DOT's definition, 5 points worse than the national rate of 77.6%. The late ones land roughly 50 minutes behind schedule. That rests on 356 flights, with a median arrival right on schedule.

The national on-time rate over the same period is 77.6%, so DL 2145 runs 5 points behind the country as a whole. Across a thousand flights that is about 53 extra late arrivals.

These figures cover 356 flights between July 2025 and June 2026. Beyond the headline rate, 8.0% of arrivals land a full hour or more behind schedule. That is the number that wrecks a connection, and it is not visible in an on-time percentage alone.

Schedule

When DL 2145 flies

DL 2145 flies MSP to SAN without a single fixed slot. Its most common scheduled departure was 18:45, used on 100 of 356 flights, with 18:59 (91 flights) and 18:46 (40 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 18:45 departure sits in the 5pm–8pm window. Across every US flight scheduled in that window the on-time rate is 68.2%, and DL 2145 runs 4 points better at 72.3%. By that time of day most aircraft have flown several legs already, and whatever went wrong earlier is still in the schedule.

Across the year

DL 2145 quarter by quarter

Quarter by quarter DL 2145 held fairly steady: 72.5% in Jul–Sep 2025, 70.5% in Oct–Dec 2025, 71.6% in Jan–Mar 2026 and 74.7% in Apr–Jun 2026. A spread of 4 points is about what a sample of this size moves on its own, so the annual figure is a fair summary.

By weekday, DL 2145 did best on Sunday at 78.0% on time and worst on Thursday at 64.0%. Each day rests on about 51 flights, so a gap of 14 points is worth noticing but could still narrow in another year.

Delay causes

Why DL 2145 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 4,956 reported delay minutes.

Carrier
36%
National Airspace System
33%
Late-arriving aircraft
29%
Extreme weather
1%

The largest share of delay minutes, 36%, 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 1,795 of the 4,956 delay minutes reported here. The split is drawn from 4,956 delay minutes reported on DL 2145.

Cancellations are rare at 0.56%, 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

8.0% 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 roughly 50 minutes, which a normal layover absorbs.

At 1,532 miles this is transcontinental flying, and long routes get a quiet structural advantage. Scheduled block time on a flight this length carries more padding in absolute minutes, so a twenty-minute late departure often still becomes an on-time arrival. Read the on-time rate here as slightly flattering next to a short-haul route with the same operational quality.

Every one of the 356 flights under DL 2145 in the data flew MSP to SAN. 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. 356 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 2145

For a booking, DL 2145 is one of the weaker ways to fly MSP to SAN: 5 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.
