Milwaukee Mitchell International Airport: TSA stops 16 firearms in 2024

Transportation Security Administration (TSA) officers stopped 16 firearms at Milwaukee Mitchell International Airport security checkpoints in 2024.

What they're saying:

"After testing the San Diego route on Saturdays during the last couple of summers, Southwest's expansion to the west coast shows that when our community supports new service by booking travel from Milwaukee’s airport, it can help convince airlines to add more flights from MKE," Airport Director Brian Dranzik said. "By stepping up and flying from MKE, we also support new jobs and boost our local Wisconsin economy."
