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.

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.
