Sit on the Left side of the plane for the best views on flights from Denver to Milwaukee. Left side wins both departure and arrival. At takeoff you get the full Rocky Mountain Front Range panorama, and on landing you get Lake Michigan and the Milwaukee lakefront. The right side offers flat plains at departure and inland Wisconsin suburbs on approach — both considerably less interesting.

During takeoff from Denver International (DEN), sit on the Left side for the best views. DEN typically departs eastward on runways 16/34 or 8/26. When departing east and banking northeast toward Milwaukee, the left side faces north and northwest, giving a clear view of the Front Range of the Rockies including Longs Peak and the Denver metro sprawl below. The right side faces southeast toward flat plains with little of interest. Notable sights include: Front Range of the Rocky Mountains, Longs Peak (14,259 ft), Denver city grid and downtown skyline, Cherry Creek Reservoir.

When landing at General Mitchell International (MKE), sit on the Left side for the best views. MKE approaches typically come from the southwest on runway 01L/19R or 07L/25R. On a southwest approach, the left side faces southeast over Lake Michigan, offering a sweeping view of the lake's western shoreline, the Milwaukee lakefront, and the city's downtown. The right side faces inland over flat Wisconsin suburbs. Notable sights include: Lake Michigan western shoreline, Milwaukee downtown and lakefront, Milwaukee Harbor, Grant Park beachfront.

The flight from Denver International (DEN) to General Mitchell International (MKE) takes Approximately 2 hours 15 minutes.

The flight tracks northeast across the Nebraska Sandhills — a vast grass-covered dune landscape — then over the Missouri River near Omaha, across Iowa's flat agricultural grid of corn and soybean fields, and finally over southern Wisconsin's rolling farmland and small lakes before descending toward Lake Michigan.
