These figures cover 291 flights between September 2025 and August 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.

A 08:50 departure sits in the 8am–11am window. Across every US flight scheduled in that window the on-time rate is 83.9%, and DL 1226 runs level with that at 85.4%. 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

The worst days
Worst days for DL 1226
The latest arrival of the period was on 20 November 2025, 4 hours 32 minutes behind schedule; most of its delay minutes were filed as carrier-caused (crew, maintenance, fuelling, baggage). The same cause led on four of the five worst days.
| Date | Arrived late by | Largest filed cause |
|---|---|---|
| 20 November 2025 | 4 hours 32 minutes | Carrier |
| 20 February 2026 | 2 hours 17 minutes | Carrier |
| 21 November 2025 | 2 hours 1 minute | Extreme weather |

Delay causes
Why DL 1226 runs late
Carrier accounts for 55% of the 1,926 delay minutes carriers reported here, and the remaining four split what is left.
- 55%Carrier
- 24%National Airspace System
- 14%Late-arriving aircraft
- 7%Extreme weather
The largest share of delay minutes, 55%, falls under carrier control: crew scheduling, maintenance, fuelling, baggage. It accounts for 1,058 of the 1,926 delay minutes reported here. The split is drawn from 1,926 delay minutes reported on DL 1226.
Cancellations are rare at 0.69%, below the national 1.89% 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 2.4% land an hour or more behind schedule, against 8.3% 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.
DL 1226 is not only a MSP to BZN flight. It also flew BZN to MSP (252 flights, 88.8% 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.

Booking DL 1226
