✈️ Flight Guide: Milwaukee (MKE) → Phoenix (PHX)

Travelers flying MKE to PHX in September should be aware of local events that can impact fares and airport traffic. In Phoenix, the Arizona State Fair typically runs in late September to October and draws significant local crowds, affecting hotel rates and ground transportation from Phoenix Sky Harbor International Airport (PHX). In Milwaukee, Doors Open Milwaukee (usually early September) and Milwaukee Brewers regular season games can increase departures from Milwaukee Mitchell International Airport (MKE) around game days. Plan accordingly by booking early, allowing extra transfer time, and checking event schedules to avoid peak crowds.

For September travel from Milwaukee Mitchell International Airport (MKE) to Phoenix Sky Harbor International Airport (PHX), the best time to fly is midweek (Tuesday–Thursday) and outside holiday weekends.

Choosing nonstop flights from Milwaukee Mitchell International Airport (MKE) to Phoenix Sky Harbor International Airport (PHX) saves time and reduces connection risk, averaging about 4 hours 10 minutes.

In September, consider nonstop for tight itineraries or if traveling with checked baggage to minimize mishandled luggage risk. If your priority is cost, a single connection with a longer layover may yield savings but increases total travel time and potential delay exposure.

For September travel, compare base fares plus baggage and seat selection fees—sometimes a slightly higher fare on a carrier with free carry-ons or checked bags is the better deal.
