Frontier Airlines has canceled four of its nonstop routes to Milwaukee as part of a nationwide network modernization.

The airline’s routes to Philadelphia International Airport and Raleigh-Durham International Airport will be suspended on August 11, and its routes to Orlando International Airport and Southwest Florida International Airport in Fort Myers, Florida, have already been suspended.

“This is part of a larger nationwide announcement as Frontier is cutting service at a number of airports across the country,” said Christie Green, marketing coordinator at Milwaukee Mitchell International Airport. “It’s not just limited to MKE. Almost all of the routes being cut at MKE are still served nonstop by other airlines.”

Travelers from Milwaukee can still fly nonstop to three of the four locations:

• Orlando, via Southwest, Spirit or Sun Country

• Philadelphia, via American

• Southwest Florida, via Southwest or Sun Country

Frontier’s media department did not immediately respond to an interview request.

Frontier’s Philadelphia and Raleigh-Durham routes had only started in May.

According to The Points Guy, the Milwaukee routes are among 43 routes that Frontier has canceled nationwide.

After the cuts, all Frontier flights to and from Milwaukee will land in Denver.
