Historical statistics for July 2025 to June 2026, not live status. For today’s DL 2614, check with Delta Air Lines.

DL 2614 lands a B, 2 points better than the national rate of 77.6%. About one flight in five 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 339 flights, with a median arrival 5 minutes early.

These figures cover 339 flights between July 2025 and June 2026. The median arrival is 5 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 2614 flies

DL 2614 flies MSP to BOS without a single fixed slot. Its most common scheduled departure was 19:59, used on 98 of 339 flights, with 20:00 (73 flights) and 20:06 (34 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 19:59 departure sits in the 5pm–8pm window. Across every US flight scheduled in that window the on-time rate is 68.2%, and DL 2614 runs 11 points better at 79.3%. 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 2614 next to MSP to BOS

Across the year

DL 2614 quarter by quarter

Quarter by quarter DL 2614 held fairly steady: 79.8% in Jul–Sep 2025, 74.1% in Oct–Dec 2025, 80.6% in Jan–Mar 2026 and 82.4% 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.

Jan–Mar 202677 flights80.6%

Scale runs 65% to 90%. Rows with fewer than 30 flights show a dash.

By weekday, DL 2614 did best on Tuesday at 86.5% on time and worst on Monday at 69.4%. Each day rests on about 48 flights, so a gap of 17 points is worth noticing but could still narrow in another year.

Delay causes

Why DL 2614 runs late

One category carries most of the weight here. Carrier accounts for 44% of the 4,327 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.

Late-arriving aircraft
32%
National Airspace System
22%
Extreme weather
3%

The largest share of delay minutes, 44%, 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 1,895 of the 4,327 delay minutes reported here. The split is drawn from 4,327 delay minutes reported on DL 2614.

Cancellations sit at 1.77% against a national 1.81%, which is ordinary. Diversions add another 0.00%.

Connections and routes

What a delay on this flight costs

6.0% 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 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 DTW to ORD (1), but none flew often enough under DL 2614 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. 339 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 2614

For a booking, read DL 2614 as 79.3% on time with 1.77% cancelled over 339 flights. Those are rates from the past twelve months, not a forecast for any particular day.
