DL 1226 earns a B+. More than four flights in five arrive inside the 15-minute window the DOT uses to define an on-time arrival, which puts it 7 points better than the national rate of 77.6%.

These figures cover 291 flights between July 2025 and June 2026. The median arrival is 10 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 1226 flies

DL 1226 flies MSP to BZN without a single fixed slot. Its most common scheduled departure was 08:55, used on 69 of 291 flights, with 11:22 (57 flights) and 11:32 (36 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 08:55 departure sits in the 8am–11am window. Across every US flight scheduled in that window the on-time rate is 84.1%, and DL 1226 runs level with that at 84.4%. Early departures usually start with an aircraft that has not flown yet that day, which is most of why the window does well.

Across the year

DL 1226 quarter by quarter

DL 1226 did not run the same all year. Its best quarter was Jul–Sep 2025 at 89.9% on time and its weakest Jan–Mar 2026 at 78.8%, a swing of 11 points on roughly 73 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 1226 did best on Tuesday at 92.9% on time and worst on Sunday at 65.9%. Each day rests on about 42 flights, so a gap of 27 points is worth noticing but could still narrow in another year.

Delay causes

Why DL 1226 runs late

One category carries most of the weight here. Carrier accounts for 52% of the 2,161 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
52%
National Airspace System
23%
Late-arriving aircraft
19%
Extreme weather
6%

The largest share of delay minutes, 52%, 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 1,121 of the 2,161 delay minutes reported here. The split is drawn from 2,161 delay minutes reported on DL 1226.

Cancellations are rare at 0.34%, below the national 1.81% and low enough to earn the plus on the grade. Roughly one flight in 100 is called off; the risk here is arriving late, not not arriving.

Connections and routes

What a delay on this flight costs

Badly late arrivals are rare here: only 2.8% land an hour or more behind schedule, against 8.1% nationally. Connections built on this flight are about as safe as US domestic connections get, though a cancelled flight still ignores every layover you give it.

The 874 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.

DL 1226 is not only a MSP to BZN flight. It also flew BZN to MSP (252 flights, 84.9% on time) often enough to be scored on its own. Airlines attach one number to several legs of an aircraft's day, and each leg keeps its own record here, so check which city pair is on your booking before reading a rate.

One caution: this is a thin sample. 291 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.
