What the record says about this route

Which airline you fly changes the odds here. Alaska Airlines arrived on time 8.3 points more often than Southwest Airlines over the same period on the same route — same airports, same weather, same air traffic control. A gap that survives all of that is about how the two airlines are run.

The shape of the lateness matters here. Flights on this route are not late often, but when they are late they are late by about 71 minutes — long enough to lose a connection or an evening. The on-time percentage looks reassuring and understates the consequence of being on the wrong flight.

The Portland to Phoenix route sits close to the middle of the record — neither notably punctual nor notably late.

Which airline should you fly on this route?

Over January 2025 – August 2026, Alaska Airlines arrived on time most often on PDX to PHX. Southwest Airlines was late most often. Flights ran closest to schedule in April and worst in November.

What these figures do and do not tell you

Everything on this page is counted from the flights that actually operated on PDX to PHX during January 2025 – August 2026, as reported by the airlines to the US Bureau of Transportation Statistics. "On time" is the federal definition: arriving at the gate within 15 minutes of the scheduled time.

A route's record is a description of the past, not a forecast. Weather, air traffic control and the aircraft's earlier flights that day drive most delays, and none of them are predictable from a historical rate. What the record does tell you is whether this route runs late more often than others, and which carrier on it has the better history — which is the part you can actually act on when you book.

Cancellations are counted separately from delays because they are a different problem for a traveller: a late flight still gets you there. How the grade is calculated →
