Continuity mistake: The plane for Paris leaves in the morning - around 10 am. Shortly after take-off (it is still morning in Chicago) it is dark outside the windows. Even though the flight path from Chicago to Paris goes a bit north, it would not get dark that fast.

Continuity mistake: When Mrs MacAllister is trying to get on the plane to Dallas, it is light in Paris. The movie cuts to evening scenes in Chicago. That cannot be. If it is evening in Chicago it is either night or very early morning in Paris - too early for it to be light. And when the plane takes off, it is darker than during check-in - showing that it is evening and not morning. December dusk in Paris is noon in Chicago.
