Historical statistics for July 2025 to June 2026, not live status. For today’s DL 1356, check with Delta Air Lines.

DL 1356 sits in the middle of the pack with a C. About seven flights in ten arrive on time by the DOT's definition, 6 points worse than the national rate of 77.6%. The late ones land a little over an hour behind schedule. That rests on 286 flights, with a median arrival 4 minutes early.

The national on-time rate over the same period is 77.6%, so DL 1356 runs 6 points behind the country as a whole. Across a thousand flights that is about 60 extra late arrivals.

These figures cover 286 flights between July 2025 and June 2026. Beyond the headline rate, 12.8% of arrivals land a full hour or more behind schedule. That is the number that wrecks a connection, and it is not visible in an on-time percentage alone.

Schedule

When DL 1356 flies

DL 1356 flies MSP to CMH without a single fixed slot. Its most common scheduled departure was 21:05, used on 39 of 286 flights, with 20:50 (33 flights) and 21:09 (30 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 21:05 departure sits in the 8pm–5am window. Across every US flight scheduled in that window the on-time rate is 70.5%, and DL 1356 runs level with that at 71.6%. 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

Across the year

DL 1356 quarter by quarter

DL 1356 did not run the same all year. Its best quarter was Apr–Jun 2026 at 81.1% on time and its weakest Jul–Sep 2025 at 63.7%, a swing of 17 points on roughly 95 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 1356 did best on Saturday at 84.6% on time and worst on Thursday at 57.5%. Each day rests on about 41 flights, so a gap of 27 points is worth noticing but could still narrow in another year.

Delay causes

Why DL 1356 runs late

One category carries most of the weight here. Carrier accounts for 50% of the 5,753 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.

Carrier
50%
Late-arriving aircraft
35%
National Airspace System
13%
Extreme weather
2%

35% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. That is a cascade, and cascades start small and grow through the day. Across 5,753 reported delay minutes here, that single category outweighs weather by 16 to one. It is the strongest argument for booking the first departure of the morning, when the aircraft has been sitting at the gate overnight with nothing to inherit. The split is drawn from 5,753 delay minutes reported on DL 1356.

Cancellations sit at 1.05% against a national 1.81%, which is ordinary. Diversions add another 0.35%.

Connections and routes

What a delay on this flight costs

For anyone connecting, the number to weigh is not the on-time rate but the tail behind it. 12.8% of arrivals land a full hour or more behind schedule, against 8.1% nationally. A 45-minute layover does not survive that, and no amount of walking quickly changes it. Ninety minutes is the honest minimum here, and two hours if the onward flight is on a separate ticket.

The 626 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 three other city pairs in the data, including MSP to PDX (19), LAS to LAX (16) and LAX to LAS (16), but none flew often enough under DL 1356 to report a rate for. Carriers move flight numbers between routes, so the figures on this page apply to MSP to CMH only.

One caution: this is a thin sample. 286 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 1356

For a booking, DL 1356 is a flight to put a long connection behind. 12.8% of its completed flights arrived an hour or more late, which a short layover will not absorb. If the onward flight is on a separate ticket, the risk sits with you.
