DL 2125 lands a B+, 3 points better than the national rate of 77.6%. About one flight in five arrives 15 minutes late or worse, and those flights are late by roughly 45 minutes on average. That is a workable record, not a spotless one. 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 2125 flies

DL 2125 flies MSP to SAN without a single fixed slot. Its most common scheduled departure was 11:00, used on 56 of 365 flights, with 11:05 (51 flights) and 11:09 (41 flights) next. Carriers retime flights through the season, so the rates here blend slightly different positions in the aircraft's day.

Scale runs 0% to 100%. Rows with fewer than 30 flights show a dash.

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

A 11:00 departure sits in the 11am–2pm window. Across every US flight scheduled in that window the on-time rate is 78.8%, and DL 2125 runs level with that at 80.5%. Midday slots inherit some of the morning's delays without yet carrying the full weight of the evening's.

Across the year

DL 2125 quarter by quarter

DL 2125 did not run the same all year. Its best quarter was Apr–Jun 2026 at 87.9% on time and its weakest Oct–Dec 2025 at 65.2%, a swing of 23 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 flights84.8%
Oct–Dec 202592 flights65.2%
Jan–Mar 202690 flights84.3%
Apr–Jun 202691 flights87.9%

Scale runs 55% to 95%. Rows with fewer than 30 flights show a dash.

By weekday, DL 2125 ranged from 75.0% on Friday to 86.5% on Wednesday. With about 52 flights behind each day, a spread of 12 points is inside normal variation, so the day you fly is not worth changing for this flight.

Delay causes

Why DL 2125 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 3,077 reported delay minutes.

National Airspace System
33%
Carrier
33%
Late-arriving aircraft
31%
Extreme weather
3%

33% of delay minutes are charged to the National Airspace System: air traffic volume, runway configuration, ground stops. No carrier can price its way out of that, which is why airport choice moves the number here more than carrier choice does. That is 1,010 minutes out of 3,077, against a national NAS share of 21%. The split is drawn from 3,077 delay minutes reported on DL 2125.

Cancellations are rare at 0.27%, 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 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.

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.

The same number turns up on one other city pair in the data, including SAN to MSP (84), but none flew often enough under DL 2125 to report a rate for. Carriers move flight numbers between routes, so the figures on this page apply to MSP to SAN only.

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 2125

For a booking, read DL 2125 as 80.5% on time with 0.27% cancelled over 365 flights. Those are rates from the past twelve months, not a forecast for any particular day.
