Flying time from STL to MKE

The total flight duration from STL to MKE is 51 minutes.

This is the average in-air flight time (wheels up to wheels down on the runway) based on actual flights taken over the past year. It covers the entire time on a typical commercial flight including take-off and landing.

If you're planning a trip, you should also factor in extra time for the plane to pull back from the gate and taxi to the runway, as well as reaching the destination gate after landing. If you include this extra time on the tarmac, the average total elapsed time from gate to gate flying from STL to MKE is 1 hour, 4 minutes.

Finally, pilots might want to estimate the flight time using an average flight speed for a commercial airliner of 500 mph, which is equivalent to 805 km/h or 434 knots. If you don't add any extra time to increase or decrease speed for take-off and landing, then at constant speed your flight time would be 38 minutes.

Note that if you fly the other direction, the flight time from MKE to STL would be 56 minutes due to the effect of winds and the jet stream.

If you're booking a flight, make sure you check the scheduled departure and arrival times. You should also factor in airport wait times and possible equipment or weather delays. If you're trying to figure out what time you'll arrive at the destination, you may want to see if there's a time difference between STL and MKE.

The calculation of flight time is based on the straight line distance from STL to MKE ("as the crow flies"), which is about 317 miles or 510 kilometers.

Your trip begins at Lambert-St. Louis International Airport in Saint Louis, Missouri.
