These figures cover 318 flights between July 2025 and June 2026. The median arrival is 2 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 2122 flies

DL 2122 flies MSP to LAX without a single fixed slot. Its most common scheduled departure was 18:25, used on 60 of 318 flights, with 18:55 (55 flights) and 18:59 (49 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 18:25 departure sits in the 5pm–8pm window. Across every US flight scheduled in that window the on-time rate is 68.2%, and DL 2122 runs 6 points better at 74.5%. 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 2122 quarter by quarter

DL 2122 did not run the same all year. Its best quarter was Jul–Sep 2025 at 82.0% on time and its weakest Apr–Jun 2026 at 67.2%, a swing of 15 points on roughly 80 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 202591 flights82.0%
Oct–Dec 202573 flights69.4%
Jan–Mar 202690 flights76.4%
Apr–Jun 202664 flights67.2%

Scale runs 60% to 85%. Rows with fewer than 30 flights show a dash.

By weekday, DL 2122 did best on Wednesday at 84.1% on time and worst on Sunday at 65.9%. Each day rests on about 45 flights, so a gap of 18 points is worth noticing but could still narrow in another year.

Delay causes

Why DL 2122 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 3,793 reported delay minutes.

Late-arriving aircraft
37%
Carrier
35%
National Airspace System
26%
Extreme weather
2%

37% 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 3,793 reported delay minutes here, that single category outweighs weather by 20 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 3,793 delay minutes reported on DL 2122.

Cancellations sit at 0.94% against a national 1.81%, which is ordinary. Diversions add another 0.31%.

Connections and routes

What a delay on this flight costs

6.4% 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 45 minutes, which a normal layover absorbs.

At 1,535 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 318 flights under DL 2122 in the data flew MSP to LAX. 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. 318 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 2122

For a booking, DL 2122 is one of the weaker ways to fly MSP to LAX: 8 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.
