What the record says about this route

The season swings this route hard. In September it ran 38.9 points more punctual than in July — a difference bigger than the one between the best and worst airlines on most routes. If the date is flexible, it is worth more than the carrier.

The two directions do not behave alike. MEM to PHX arrives on time 12.3 points more often than the outbound. Delay accumulates through the flying day, so whichever direction is scheduled later tends to carry the worse record — which is an argument for booking the morning departure if the choice exists.

The route has been getting better. The later months in the record run 11.5 points more punctual than the earlier ones, which usually means a schedule that was too tight has been given more room.

This is a thin route — 514 flights across the whole period. On a route this infrequent a cancellation is far more costly than the rate suggests, because the next departure may not be the same day.

Which airline should you fly on this route?

Over January 2025 – August 2026, Southwest Airlines arrived on time most often on PHX to MEM. American Airlines was late most often. Flights ran closest to schedule in September and worst in July.

What these figures do and do not tell you

Everything on this page is counted from the flights that actually operated on PHX to MEM 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 →
