These figures cover 342 flights between September 2025 and August 2026. On-time means an arrival less than 15 minutes after the scheduled gate time, the same threshold the Department of Transportation uses in its own reports. Cancelled and diverted flights are excluded from the on-time rate and counted separately, which is why the cancellation column matters on its own.

Across the year

DL 756 quarter by quarter

DL 756 did not run the same all year. Its best quarter was Oct–Dec 2025 at 78.2% on time and its weakest Apr–Jun 2026 at 57.1%, a swing of 21 points on roughly 86 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.

Scale runs 50% to 85%. Rows with fewer than 30 flights show a dash.

By weekday, DL 756 did best on Tuesday at 85.7% on time and worst on Thursday at 63.3%. Each day rests on about 49 flights, so a gap of 22 points is worth noticing but could still narrow in another year.

Share of 342 completed flights by arrival against schedule.

14 of 72 late departures made up the time and arrived on time, 19% of them. In the other direction, 43 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 SFO.

The worst days

Worst days for DL 756

The latest arrival of the period was on 31 July 2026, 4 hours 19 minutes behind schedule; most of its delay minutes were filed as a late-arriving aircraft. On three of the five worst days the largest share was filed as carrier-caused (crew, maintenance, fuelling, baggage).

Delay causes

Why DL 756 runs late

National Airspace System accounts for 51% of the 4,829 delay minutes carriers reported here, and the remaining four split what is left.

National Airspace System
51%
Carrier
35%
Late-arriving aircraft
14%
Extreme weather
1%

51% 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 2,446 minutes out of 4,829, against a national NAS share of 21%. The split is drawn from 4,829 delay minutes reported on DL 756.

Cancellations are rare at 0.00%, below the national 1.89% and low enough to earn the plus on the grade. Almost no flights are called off; the risk here is arriving late, not not arriving.

Connections and routes

What a delay on this flight costs

6.1% 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.

At 1,589 miles this is transcontinental flying, and long routes get a quiet structural advantage. Scheduled block time on a flight this length carries more padding in absolute minutes, so a twenty-minute late departure often still becomes an on-time arrival. Read the on-time rate here as slightly flattering next to a short-haul route with the same operational quality.

The same number turns up on two other city pairs in the data, including SFO to MSP (79) and BTR to ATL (16), but none flew often enough under DL 756 to report a rate for. Carriers move flight numbers between routes, so the figures on this page apply to MSP to SFO 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 756

For a booking, read DL 756 as 70.5% on time with 0.00% cancelled over 342 flights. Those are rates from the past twelve months, not a forecast for any particular day.
