DL 2649 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 15 points better than the national rate of 77.6%.

These figures cover 355 flights between July 2025 and June 2026. The median arrival is 14 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 2649 flies

DL 2649 flies MSP to BOS without a single fixed slot. Its most common scheduled departure was 06:55, used on 172 of 355 flights, with 07:00 (104 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 06:55 departure sits in the 5am–8am window. Across every US flight scheduled in that window the on-time rate is 89.3%, and DL 2649 runs 3 points better at 92.6%. 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 2649 quarter by quarter

Quarter by quarter DL 2649 held fairly steady: 95.6% in Jul–Sep 2025, 91.9% in Oct–Dec 2025, 87.8% in Jan–Mar 2026 and 94.5% in Apr–Jun 2026. A spread of 8 points is about what a sample of this size moves on its own, so the annual figure is a fair summary.

By weekday, DL 2649 ranged from 88.5% on Wednesday to 95.9% on Monday. With about 51 flights behind each day, a spread of 7 points is inside normal variation, so the day you fly is not worth changing for this flight.

Delay causes

Why DL 2649 runs late

One category carries most of the weight here. National Airspace System accounts for 54% of the 885 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
1%

54% of delay minutes are charged to the National Airspace System: air traffic volume, runway configuration, ground stops. No carrier can price its way out of that, which is why airport choice moves the number here more than carrier choice does. That is 482 minutes out of 885, against a national NAS share of 21%. The split is drawn from 885 delay minutes reported on DL 2649.

Cancellations sit at 1.41% against a national 1.81%, which is ordinary. Diversions add another 0.00%.

Connections and routes

What a delay on this flight costs

Badly late arrivals are rare here: only 0.9% land an hour or more behind schedule, against 8.1% nationally. Connections built on this flight are about as safe as US domestic connections get, though a cancelled flight still ignores every layover you give it.

The 1,124 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 MSP to MSN (1), but none flew often enough under DL 2649 to report a rate for. Carriers move flight numbers between routes, so the figures on this page apply to MSP to BOS only.

One caution: this is a thin sample. 355 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 2649

For a booking, DL 2649 has one of the better records a US domestic flight can show: 92.6% on time and 1.41% cancelled. That is a base rate, not a promise about any single day.
