These figures cover 245 flights between September 2025 and August 2026. The median arrival is 11 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.

The worst days
Worst days for Alaska on PDX to MSP
The latest arrival of the period was on 16 June 2026, 2 hours 17 minutes behind schedule; most of its delay minutes were filed as carrier-caused (crew, maintenance, fuelling, baggage). The five worst days are spread across June, July, August and December, with no single month standing out.
| Date | Arrived late by | Largest filed cause |
|---|---|---|
| 16 June 2026 | 2 hours 17 minutes | Carrier |
| 15 July 2026 | 52 minutes | Late-arriving aircraft |
| 27 August 2026 | 43 minutes | Late-arriving aircraft |

Delay causes
Why Alaska runs late on this route
Carrier accounts for 46% of the 683 delay minutes carriers reported here, and the remaining four split what is left.
- 46%Carrier
- 33%National Airspace System
- 21%Late-arriving aircraft
The largest share of delay minutes, 46%, falls under carrier control: crew scheduling, maintenance, fuelling, baggage. It accounts for 311 of the 683 delay minutes reported here. The split is drawn from 683 reported delay minutes.
33% 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 227 minutes out of 683, against a national NAS share of 21%.
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 stage length
What a delay here costs
Badly late arrivals are rare here: only 0.4% 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 1,426 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.
The return leg is a different operation and performs like one: it runs 83.9% on time across 245 flights, 7 points below this direction. Departure banks, aircraft rotations and the congestion at each end all differ, so scoring the two directions together would average away a real 7 points of difference.
One caution: this is a thin sample. 245 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 Alaska on PDX to MSP
Put together: treat all of this as provisional. 245 flights over twelve months is enough to clear this site's floor and not enough to be confident to better than a couple of points. The 91.0% headline is the most reliable number on the page; the hour and month splits below it are built on a few dozen flights each. 244 completed flights over 12 months sit behind that.
