Share of 347 completed flights by arrival against schedule.
Time lost at the gate mostly stays lost. Of 104 departures that left 15 minutes late or more, only 11 made it up before arrival. In the other direction, 27 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 DEN.
The worst days
Worst days for DL 2931
The latest arrival of the period was on 19 June 2026, 7 hours 27 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 |
|---|---|---|
| 19 June 2026 | 7 hours 27 minutes | Carrier |
| 7 December 2025 | 7 hours 7 minutes | Late-arriving aircraft |
| 18 December 2025 | 4 hours 58 minutes | Carrier |
| 25 January 2026 | 4 hours 47 minutes | Carrier |
| 14 August 2026 | 4 hours 7 minutes | National Airspace System |
Delay causes
Why DL 2931 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 8,468 reported delay minutes.
- 40%Carrier
- 39%National Airspace System
- 21%Late-arriving aircraft
- 0%Extreme weather
The largest share of delay minutes, 40%, falls under carrier control: crew scheduling, maintenance, fuelling, baggage. It accounts for 3,403 of the 8,468 delay minutes reported here. The split is drawn from 8,468 delay minutes reported on DL 2931.
Cancellations are rare at 0.86%, 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
14.1% of arrivals land a full hour or more behind schedule, against 8.3% nationally. Ninety minutes is the honest minimum for a connection here, and two hours if the onward flight is on a separate ticket.
The 680 miles between these two airports put this in the middle of the US network, around two and a half to three hours of block time. That is enough cruise to absorb a ten-minute late pushback and not enough to absorb thirty.
Every one of the 350 flights under DL 2931 in the data flew MSP to DEN. 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. 350 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 2931
For a booking, DL 2931 is a flight to put a long connection behind. 14.1% of its completed flights arrived an hour or more late, which a short layover will not absorb. If the onward flight is on a separate ticket, the risk sits with you.
