These figures cover 284 flights between July 2025 and June 2026. The median arrival is 10 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 2191 flies

DL 2191 flies SAN to MSP without a single fixed slot. Its most common scheduled departure was 16:35, used on 61 of 284 flights, with 17:45 (31 flights) and 15:30 (31 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 16:35 departure sits in the 2pm–5pm window. Across every US flight scheduled in that window the on-time rate is 72.4%, and DL 2191 runs 12 points better at 84.4%. Midday slots inherit some of the morning's delays without yet carrying the full weight of the evening's.

Across the year

DL 2191 quarter by quarter

DL 2191 did not run the same all year. Its best quarter was Apr–Jun 2026 at 88.4% on time and its weakest Jul–Sep 2025 at 77.0%, a swing of 11 points on roughly 71 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 2191 did best on Friday at 93.0% on time and worst on Sunday at 76.1%. Each day rests on about 41 flights, so a gap of 17 points is worth noticing but could still narrow in another year.

Delay causes

Why DL 2191 runs late

One category carries most of the weight here. Late-arriving aircraft accounts for 47% of the 3,301 delay minutes carriers reported, and the remaining four split what is left. The split is by minutes rather than by flights, so a few very long delays count for as much as many short ones.

41%

47% 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 3,301 reported delay minutes here, that single category outweighs weather by 47 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 3,301 delay minutes reported on DL 2191.

Cancellations are rare at 0.00%, below the national 1.81% and low enough to earn the plus on the grade. Almost no flights are called off; the risk here is arriving late, not not arriving.

Connections and routes

What a delay on this flight costs

5.7% 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 a little over an hour, 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 284 flights under DL 2191 in the data flew SAN to MSP. 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. 284 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 2191

For a booking, read DL 2191 as 84.4% on time with 0.00% cancelled over 284 flights. Those are rates from the past twelve months, not a forecast for any particular day.
