You land at MKE, grab your bags from the carousel, and head toward the rental car center. If you’ve booked with Sixt rent a car Milwaukee airport, you’re likely expecting that signature orange glow and a fleet of BMWs or Audis that look a lot sharper than the beige sedans at the other counters. But here’s the thing: Milwaukee isn't Miami. The experience at General Mitchell International (MKE) has its own set of quirks that can either make your trip seamless or leave you standing in a cold parking garage wondering where your "premium" upgrade went.
Honestly, people choose Sixt because they want a European driving experience at a Midwest price point. It’s a solid strategy. Usually, it works.
Milwaukee is a unique market for car rentals. You have a mix of business travelers heading to Kohl’s corporate or Northwestern Mutual and leisure travelers hitting the Summerfest grounds or a Bucks game. Because of this, the inventory at Sixt rent a car Milwaukee airport fluctuates wildly. One day it’s all X3s and Volvos; the next, you might find yourself looking at a very clean, very sensible Toyota because the "premium" fleet got cleaned out by a convention.
The MKE Layout: Finding the Orange Counter Without Getting Lost
First off, don't look for a shuttle.
At many major hubs, you have to lug your suitcases onto a crowded bus just to get to the rental lot. Not here. Milwaukee is surprisingly civilized in this regard. The rental car counters, including Sixt, are located right across from the baggage claim area in the parking garage. You just walk across the skywalk. It’s fast. It’s covered. If it’s January and the wind is whipping off Lake Michigan at 30 miles per hour, you will be deeply grateful for this architectural choice.
Sixt sits alongside the "big guys" like Hertz and Enterprise. However, because Sixt is technically a newer player in the Milwaukee market compared to the legacy brands, their counter staff is often smaller. If three flights land at once, that line moves a bit slower. That’s just the reality.
Why the "Upgrade" Game is Different in Wisconsin
Everyone wants the upgrade. We all want to pay for a Jetta and drive away in a Mercedes C-Class. At the Sixt rent a car Milwaukee airport location, the fleet mix is heavily weighted toward German engineering, which is their brand's bread and butter.
But here is a pro tip: check the weather.
If there is a blizzard warning, everyone suddenly wants the AWD SUVs. If you booked a "Luxury" category which happens to be a rear-wheel-drive sedan, you might find yourself in a bit of a pickle. Sixt is generally good about substitutions, but in Milwaukee, the demand for Quattro or xDrive systems is non-negotiable for about five months of the year.

I’ve seen travelers get frustrated because they couldn't get the specific convertible they saw online. Look, it's Milwaukee. Even in July, the "convertible" fleet is tiny. If you absolutely need a specific car for a wedding or a high-profile meeting, call the branch directly 48 hours in advance. Don't just rely on the app's confirmation.
Hidden Costs and the "MKE" Premium
Let’s talk money. Nobody likes the "total" at the bottom of the receipt being $200 higher than the quote.
When booking Sixt rent a car Milwaukee airport, you have to account for the airport concession recovery fees and the Wisconsin state rental taxes. These aren't Sixt's fault—they're just the price of doing business at Mitchell International. Currently, you’re looking at an 11% state/local tax plus a facility fee that usually hovers around $8 per day.
Then there’s the insurance.
Sixt agents are trained to be... let's say "persuasive" about their Loss Damage Waiver (LDW). If you have a high-end credit card like the Chase Sapphire Reserve or the Amex Platinum, you likely already have primary rental coverage. Use it. But—and this is a big "but"—make sure your personal insurance covers "loss of use." If you wreck a Sixt Mercedes and they can't rent it out for two weeks while it's in the shop, they will bill you for those two weeks of lost revenue. Many credit cards don't cover that specific line item.
The Toll Road Reality
If you are driving south toward Chicago, you’re hitting tolls. Period.
Sixt offers a toll pass program. It’s expensive. Basically, you pay a flat daily rate for the "convenience" of not stopping. If you’re only going to Kenosha, don’t buy it. If you’re driving into the heart of the Loop in Chicago, it might save you the headache of navigating the Illinois Tollway's online payment system (which is notoriously clunky for out-of-state plates).
Fueling Up Before the Return: The $10 Mistake
Returning the car to Sixt rent a car Milwaukee airport is straightforward, but the refueling situation is a trap for the uninitiated.

The closest gas stations to the airport often have prices $0.50 to $1.00 higher per gallon than stations just three miles away. If you’re coming from the south, hit the stations on Howell Ave or 27th St before you get into the immediate airport perimeter.
Also, Sixt is notoriously picky about the fuel needle. If it’s even a hair below "Full," they might hit you with their internal refueling rate, which is usually double or triple the market price. Just take the extra five minutes to top it off.
What About the "Digital Key" Experience?
Sixt has been pushing their app-based check-in hard. In theory, you skip the counter, go to the car, and drive away.
In Milwaukee, this is hit or miss.
The cellular reception in the MKE parking garage can be spotty. I’ve seen people standing next to a beautiful BMW 5 Series, frantically waving their phones around trying to get the Bluetooth to sync so the doors will unlock. It’s usually faster to just talk to the human at the desk, especially if you have any questions about the car's features. These cars are tech-heavy; if you’ve never operated a modern iDrive system, you don’t want to be figuring it out while trying to exit a dark parking structure.
Customer Service Nuance
Sixt is a premium brand, but they are a franchise-heavy or corporate-standardized operation that sometimes struggles with the "Midwest Nice" expectation.
In Milwaukee, people expect a certain level of chatty, friendly service. Sixt can sometimes feel a bit more "efficient" and "transactional." Don't mistake brevity for rudeness. They are just trying to get through the queue.
However, if there is a scratch on the car that isn't on the diagram, take a photo immediately. I cannot stress this enough. Use your phone to take a 360-degree video of the car in the garage before you pull out. The lighting in the MKE garage is okay, but it can hide small dents. Sixt’s claims department is known for being thorough. You want your own evidence.

The Comparison: Sixt vs. The Field
Why choose Sixt rent a car Milwaukee airport over, say, National or Avis?
- The Fleet: If you want a Cadillac, go to National. If you want an Audi A4 or a Volvo XC90, Sixt is your best bet.
- The Price: Surprisingly, Sixt is often cheaper than the "budget" brands if you book 14+ days out. They use aggressive pricing algorithms.
- The Age of Cars: Sixt tends to cycle their fleet faster. You are rarely going to get a car with more than 20,000 miles on it here.
On the downside, their "additional driver" fees are often higher than competitors. If you’re traveling with a spouse, check if your status (like Sixt Gold or Platinum) waives that fee. Otherwise, it adds up fast.
Actionable Steps for a Better Rental Experience
To ensure you actually get the "premium" experience you're paying for at the Milwaukee airport, follow these specific steps:
1. Join the Sixt Advantage Circle immediately. It’s free. Even the basic tier gets you a slightly faster check-in process. If you have status with an airline or another rental agency, Sixt will often status-match you to their Gold or Platinum tier, which significantly increases your chance of a free upgrade at the MKE counter.
2. Book the "Or Similar" with eyes wide open.
In the rental world, "BMW 3 Series or similar" could mean a Volkswagen Jetta in a worst-case scenario. If the "similar" car is a dealbreaker for you, call the Milwaukee branch at +1-414-764-1100 a few hours before arrival. Ask what’s actually on the lot. If they only have Altimas left, you might want to pivot.
3. Inspect the tires in winter. This is a Milwaukee-specific tip. If you’re renting from Sixt rent a car Milwaukee airport between November and March, look at the tread. A high-performance car with "summer" or worn-out "all-season" tires is a liability on I-94 during a lake-effect snowstorm. If the tires look bald, ask for a different unit. They have plenty.
4. Document everything at drop-off.
When you return the car, don't just drop the keys and run. Take another quick video of the exterior and the fuel gauge. If you return the car after-hours (Sixt MKE usually closes their counter late but not 24/7), this video is your only insurance against "new" damage claims that might happen after you leave.
5. Check the "Pre-paid Fuel" math.
Unless you are returning the car at 4:00 AM and are in a massive rush, the pre-paid fuel option at MKE is almost always a bad deal. There is a Shell and a BP within two miles of the airport. Use them.
Milwaukee is a fantastic city to drive in—the "Hoan Bridge" view of the skyline is one of the best in the country. Doing it in a car that actually has some soul makes the trip better. Just be smart about the logistics at Mitchell International, and you'll avoid the common pitfalls that trip up most travelers.
