It's always helpful to have a sense of what to expect when you're traveling, especially when it comes to flights. For those looking into Delta Air Lines flight 4166, which operates between Detroit Metropolitan Wayne County Airport (DTW) and Appleton International Airport (ATW), understanding its typical schedule and how it has performed in the past can offer some peace of mind.
This particular route, often operated by SkyWest Airlines on behalf of Delta, is usually flown on a Canadair (Bombardier) Regional Jet 900 or similar aircraft. The scheduled flight time is typically around 1 hour and 30 minutes. For instance, on December 27, 2025, the flight was scheduled to depart from Detroit (DTW) at 4:05 PM EST, with an expected arrival in Appleton (ATW) at 4:35 PM CST. The aircraft was slated to depart from Terminal M, Gate A45 in Detroit.

For travelers, keeping an eye on real-time updates is always the best approach. Services that allow you to set flight alerts or view live status can be incredibly useful. While the historical data gives us a good idea of what to expect, the dynamic nature of air travel means that checking for the most current information right before your journey is key to a smooth experience.
