Across the year

DL 2145 quarter by quarter

DL 2145 did not run the same all year. Its best quarter was Apr–Jun 2026 at 74.7% on time and its weakest Jul–Sep 2026 at 63.9%, a swing of 11 points on roughly 89 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.

By weekday, DL 2145 did best on Wednesday at 83.0% on time and worst on Thursday at 56.0%. Each day rests on about 51 flights, so a gap of 27 points is worth noticing but could still narrow in another year.

Share of 349 completed flights by arrival against schedule.

Time lost at the gate mostly stays lost. Of 76 departures that left 15 minutes late or more, only 8 made it up before arrival. In the other direction, 34 flights left on time yet arrived 15 minutes late or more, so that delay built up after pushback: in the air, in a holding pattern or on the ground at SAN.

The worst days

Worst days for DL 2145

The latest arrival of the period was on 6 August 2026, 4 hours 25 minutes behind schedule; most of its delay minutes were filed as carrier-caused (crew, maintenance, fuelling, baggage). The same cause led on four of the five worst days.

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 5,159 reported delay minutes.

National Airspace System
38%
Carrier
37%
Late-arriving aircraft
24%
Extreme weather
1%

The largest share of delay minutes, 37%, falls under carrier control: crew scheduling, maintenance, fuelling, baggage. It accounts for 1,911 of the 5,159 delay minutes reported here. The split is drawn from 5,159 delay minutes reported on DL 2145.

Cancellations are rare at 0.56%, 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

8.6% of arrivals land an hour or more late, close to the national 8.3%, so a 60 to 75 minute layover is reasonable here while anything under 45 minutes is a bet. Most delays on this route last about 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 355 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. 355 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: 7 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.
