These figures cover 348 flights between September 2025 and August 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.

Across the year
DL 674 quarter by quarter
DL 674 did not run the same all year. Its best quarter was Jul–Sep 2025 at 100.0% on time and its weakest Apr–Jun 2026 at 70.3%, a swing of 30 points on roughly 70 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.

- Oct–Dec 202579 flights76.9%
- Jan–Mar 202686 flights73.8%

Scale runs 60% to 100%.
By weekday, DL 674 did best on Tuesday at 86.0% on time and worst on Saturday at 70.8%. Each day rests on about 50 flights, so a gap of 15 points is worth noticing but could still narrow in another year.
Arrival by arrival
How late DL 674 runs when it is late
DL 674 often beats the schedule: 130 of 345 completed flights, 38%, arrived 15 minutes or more early. The 82 late arrivals split 38 under half an hour, 24 between 30 and 60 minutes, and 20 an hour or more.

Share of 345 completed flights by arrival against schedule.
Time lost at the gate mostly stays lost. Of 65 departures that left 15 minutes late or more, only 7 made it up before arrival. In the other direction, 24 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 IND.
The worst days
Worst days for DL 674
The latest arrival of the period was on 9 December 2025, 10 hours 21 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 |
|---|---|---|
| 9 December 2025 | 10 hours 21 minutes | Carrier |
| 17 April 2026 | 2 hours 39 minutes | Late-arriving aircraft |
| 31 January 2026 | 2 hours 36 minutes | Carrier |
| 29 November 2025 | 2 hours 20 minutes | Extreme weather |
| 30 November 2025 | 2 hours 4 minutes | Carrier |
Delay causes
Why DL 674 runs late
Carrier accounts for 57% of the 4,114 delay minutes carriers reported here, and the remaining four split what is left.
- 57%Carrier
- 22%National Airspace System
- 14%Late-arriving aircraft
- 6%Extreme weather
The largest share of delay minutes, 57%, falls under carrier control: crew scheduling, maintenance, fuelling, baggage. It accounts for 2,341 of the 4,114 delay minutes reported here. The split is drawn from 4,114 delay minutes reported on DL 674.
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
5.8% 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 about 50 minutes, which a normal layover absorbs.
The 503 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.
The same number turns up on one other city pair in the data, including SLC to SNA (12), but none flew often enough under DL 674 to report a rate for. Carriers move flight numbers between routes, so the figures on this page apply to MSP to IND only.
One caution: this is a thin sample. 348 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 674
For a booking, read DL 674 as 76.2% on time with 0.86% cancelled over 348 flights. Those are rates from the past twelve months, not a forecast for any particular day.
