Two main traps catch drivers out at Milwaukee Airport: rigid credit card rules at the desk and slow queues with the highest-rated brands. All 8 companies are located inside the terminal, but 5 flatly refuse debit cards for the security hold. Desks like National and Alamo score over 90/100 for overall quality, yet you can expect to spend 23 or 24 minutes standing at the counter before you get your keys. Turning right on red after stopping is legal in Wisconsin unless a sign says otherwise, which can surprise drivers who sit waiting at empty junctions.

Only 51% of prices at Milwaukee Airport are full tank out, full tank back, so read the fuel line under the car before you book.

Intermediate cars like the Volkswagen Jetta offer the balanced choice at Milwaukee Airport, priced at around £43 a day in October 2026. They seat 5 people but take only 3 bags, meaning a full party travelling with large suitcases will soon run out of boot room. Upgrading to a Fullsize car like the Chevrolet Malibu provides 6 seats and 4 bags for £51 a day, whereas a Compact car like the Nissan Versa costs £40. Every car offered is an automatic. No electric or hybrid cars are offered in the fleet, so expect a petrol model.
