DL 1641 earns an A−. Close to nine flights in ten arrive inside the 15-minute window the DOT uses to define an on-time arrival, which puts it 11 points better than the national rate of 77.6%. When something does go wrong the average delay runs about 2.8 hours. That rests on 365 flights, with a median arrival 15 minutes early.

Set against the rest of the country, DL 1641's record is 11 points better than the US average of 77.6%. That gap is worth roughly 109 fewer late arrivals for every thousand flights.

These figures cover 365 flights between July 2025 and June 2026. The median arrival is 15 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 1641 flies

DL 1641 flies EWR to MSP without a single fixed slot. Its most common scheduled departure was 06:15, used on 141 of 365 flights, with 06:00 (100 flights) and 06:20 (41 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 06:15 departure sits in the 5am–8am window. Across every US flight scheduled in that window the on-time rate is 89.3%, and DL 1641 runs level with that at 88.5%. Early departures usually start with an aircraft that has not flown yet that day, which is most of why the window does well.

Across the year

DL 1641 quarter by quarter

Quarter by quarter DL 1641 held fairly steady: 88.9% in Jul–Sep 2025, 88.2% in Oct–Dec 2025, 89.4% in Jan–Mar 2026 and 87.5% in Apr–Jun 2026. A spread of 2 points is about what a sample of this size moves on its own, so the annual figure is a fair summary.

Oct–Dec 202592 flights88.2%
Jan–Mar 202690 flights89.4%

Scale runs 80% to 95%. Rows with fewer than 30 flights show a dash.

By weekday, DL 1641 ranged from 82.0% on Tuesday to 92.2% on Thursday. With about 52 flights behind each day, a spread of 10 points is inside normal variation, so the day you fly is not worth changing for this flight.

Delay causes

Why DL 1641 runs late

One category carries most of the weight here. Carrier accounts for 80% of the 6,643 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.

Extreme weather
4%

The largest share of delay minutes, 80%, falls under carrier control: crew scheduling, maintenance, fuelling, baggage. Unlike weather, that is a management outcome, and it is the category where the gap between two carriers on the same schedule is genuinely earned. It accounts for 5,309 of the 6,643 delay minutes reported here. The split is drawn from 6,643 delay minutes reported on DL 1641.

Cancellations run at 4.66%, against 1.81% nationally. That is about one flight in twenty cancelled outright. A cancelled flight is invisible in every on-time figure on this page, so the punctuality numbers above describe only the flights that actually operated.

Connections and routes

What a delay on this flight costs

6.9% 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 2.8 hours, which a normal layover absorbs.

The 1,008 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.

Every one of the 365 flights under DL 1641 in the data flew EWR 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. 365 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 1641

For a booking, the cancellation rate is the figure to plan around on DL 1641: 4.66% of its 365 scheduled flights did not operate. A late arrival costs about 2.8 hours, but a cancellation costs the day, so leave a later option open.
