These figures cover 342 flights between September 2025 and August 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.

Across the year
DL 2614 quarter by quarter
DL 2614 did not run the same all year. Its best quarter was Jul–Sep 2025 at 86.7% on time and its weakest Jul–Sep 2026 at 62.3%, a swing of 24 points on roughly 68 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.

By weekday, DL 2614 did best on Friday at 86.5% on time and worst on Thursday at 68.6%. Each day rests on about 49 flights, so a gap of 18 points is worth noticing but could still narrow in another year.
Arrival by arrival
How late DL 2614 runs when it is late
DL 2614 often beats the schedule: 116 of 335 completed flights, 35%, arrived 15 minutes or more early. The 78 late arrivals split 26 under half an hour, 31 between 30 and 60 minutes, and 21 an hour or more.

Share of 335 completed flights by arrival against schedule.
A late pushback is often recovered here: of 81 departures that left 15 minutes late or more, 25 still arrived on time. In the other direction, 22 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 BOS.
The worst days
Worst days for DL 2614
The latest arrival of the period was on 22 July 2026, 5 hours 13 minutes behind schedule; most of its delay minutes were filed as carrier-caused (crew, maintenance, fuelling, baggage). On three of the five worst days the largest share was filed as a late-arriving aircraft.
| Date | Arrived late by | Largest filed cause |
|---|---|---|
| 22 July 2026 | 5 hours 13 minutes | Carrier |
| 28 December 2025 | 3 hours 10 minutes | Late-arriving aircraft |
| 15 March 2026 | 3 hours 2 minutes | Carrier |
| 13 October 2025 | 3 hours 1 minute | Late-arriving aircraft |
| 16 July 2026 | 2 hours 21 minutes | Late-arriving aircraft |
Delay causes
Why DL 2614 runs late
Carriers report a reason for every delay minute they cause, in five DOT categories. The split below is by minutes, not by number of flights, so a handful of very long weather delays weighs as much as many short ones. It covers 4,044 reported delay minutes.
- 39%Late-arriving aircraft
- 30%National Airspace System
- 30%Carrier
- 1%Extreme weather
39% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. Across 4,044 reported delay minutes here, that single category outweighs weather by 28 to one. The split is drawn from 4,044 delay minutes reported on DL 2614.
Cancellations sit at 2.05% against a national 1.89%, which is ordinary. Diversions add another 0.00%.
Connections and routes
What a delay on this flight costs
6.3% 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 roughly 50 minutes, 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.
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. 342 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 76.7% on time with 2.05% cancelled over 342 flights. Those are rates from the past twelve months, not a forecast for any particular day.
