Historical statistics for July 2025 to June 2026, not live status. For today’s DL 756, check with Delta Air Lines.

DL 756 sits in the middle of the pack with a C+. About seven flights in ten arrive on time by the DOT's definition, 5 points worse than the national rate of 77.6%. The late ones land about 50 minutes behind schedule. That rests on 342 flights, with a median arrival 2 minutes early.

The national on-time rate over the same period is 77.6%, so DL 756 runs 5 points behind the country as a whole. Across a thousand flights that is about 48 extra late arrivals.

These figures cover 342 flights between July 2025 and June 2026. The median arrival is 2 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 756 flies

DL 756 flies MSP to SFO without a single fixed slot. Its most common scheduled departure was 18:40, used on 58 of 342 flights, with 18:45 (53 flights) and 15:55 (45 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 18:40 departure sits in the 5pm–8pm window. Across every US flight scheduled in that window the on-time rate is 68.2%, and DL 756 runs 5 points better at 72.8%. 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 756 next to MSP to SFO

Across the year

DL 756 quarter by quarter

DL 756 did not run the same all year. Its best quarter was Jul–Sep 2025 at 81.6% on time and its weakest Apr–Jun 2026 at 57.1%, a swing of 24 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.

Jan–Mar 202686 flights75.6%

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

By weekday, DL 756 did best on Tuesday at 86.0% on time and worst on Monday at 66.0%. Each day rests on about 49 flights, so a gap of 20 points is worth noticing but could still narrow in another year.

Delay causes

Why DL 756 runs late

One category carries most of the weight here. National Airspace System accounts for 48% of the 4,641 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
2%

48% 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 2,205 minutes out of 4,641, against a national NAS share of 21%. The split is drawn from 4,641 delay minutes reported on DL 756.

Cancellations are rare at 0.00%, below the national 1.81% 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

5.8% 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 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 (45) 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 72.8% on time with 0.00% cancelled over 342 flights. Those are rates from the past twelve months, not a forecast for any particular day.
