Historical statistics for July 2025 to June 2026, not live status. For today’s DL 674, check with Delta Air Lines.

DL 674 lands a B+, about a point worse than the national rate of 77.6%. About one flight in four arrives 15 minutes late or worse, and those flights are late by about an hour on average. That is a workable record, not a spotless one. That rests on 348 flights, with a median arrival 9 minutes early.

These figures cover 348 flights between July 2025 and June 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.

Schedule

When DL 674 flies

DL 674 flies MSP to IND without a single fixed slot. Its most common scheduled departure was 20:25, used on 44 of 348 flights, with 21:07 (36 flights) and 20:40 (35 flights) next. Carriers retime flights through the season, so the rates here blend slightly different positions in the aircraft's day.

  • Departs 20:2544 flights12.6%
  • Departs 21:0736 flights10.3%
  • Departs 20:4035 flights10.1%

Scale runs 0% to 100%. Rows with fewer than 30 flights show a dash.

Share of scheduled departures at each local time. Times used on fewer than one flight in ten are not listed.

A 20:25 departure sits in the 8pm–5am window. Across every US flight scheduled in that window the on-time rate is 70.5%, and DL 674 runs 6 points better at 76.2%. By that time of day most aircraft have flown several legs already, and whatever went wrong earlier is still in the schedule.

Against the route

DL 674 next to MSP to IND

Every carrier on MSP to IND combined arrived on time 79.8% of the time across 1,243 flights, so DL 674 is 4 points behind it. Delta flew 987 flights on the same city pair under all its flight numbers, including this one, and those ran 80.7% on time. Across its whole network Delta Air Lines managed 81.6%, which this flight trails by 5 points.

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 83.7% on time and its weakest Apr–Jun 2026 at 70.3%, a swing of 13 points on roughly 87 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 202592 flights83.7%
  • Oct–Dec 202579 flights76.9%
  • Jan–Mar 202686 flights73.8%

Scale runs 60% to 90%. Rows with fewer than 30 flights show a dash.

By weekday, DL 674 did best on Wednesday at 87.8% on time and worst on Saturday at 66.7%. Each day rests on about 50 flights, so a gap of 21 points is worth noticing but could still narrow in another year.

Delay causes

Why DL 674 runs late

One category carries most of the weight here. Carrier accounts for 50% of the 4,864 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.

  • Carrier
    50%
  • National Airspace System
    19%
  • Extreme weather
    18%
  • Late-arriving aircraft
    13%

Extreme weather accounts for 18% of delay minutes, well above the single-digit share typical across the system. Weather delays are lumpy: they arrive as whole bad days rather than as a steady drag, so the quarterly figures above are the more useful view of the risk. The national share is 6%, so this operation carries roughly 2.9 times the usual weather exposure. The split is drawn from 4,864 delay minutes reported on DL 674.

Cancellations are rare at 0.86%, below the national 1.81% 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

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 about an hour, 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. It is also long enough that the aircraft usually flies three or four legs a day rather than six, which slows how fast delay compounds.

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.
