These figures cover 300 flights between September 2025 and August 2026. The median arrival is 9 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.

The worst days
Worst days for DL 2191
The latest arrival of the period was on 14 October 2025, 16 hours 26 minutes behind schedule; most of its delay minutes were filed as carrier-caused (crew, maintenance, fuelling, baggage). The same cause led on three of the five worst days.
| Date | Arrived late by | Largest filed cause |
|---|---|---|
| 14 October 2025 | 16 hours 26 minutes | Carrier |
| 16 March 2026 | 4 hours 36 minutes | Late-arriving aircraft |
| 27 July 2026 | 3 hours 50 minutes | Carrier |
| 15 September 2025 | 2 hours 32 minutes | Carrier |

Delay causes
Why DL 2191 runs late
Late-arriving aircraft accounts for 43% of the 3,678 delay minutes carriers reported here, and the remaining four split what is left.
- 43%Late-arriving aircraft
- 43%Carrier
- 13%National Airspace System
43% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. Across 3,678 reported delay minutes here, that single category outweighs weather by 43 to one. The split is drawn from 3,678 delay minutes reported on DL 2191.
Cancellations are rare at 0.00%, below the national 1.89% 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 8.3%, so a 60 to 75 minute layover is reasonable here while anything under 45 minutes is a bet. Most delays on this route last 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 300 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. 300 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.
