What the aircraft actually flies over

From Los Angeles the path crosses the United States.

The furthest the great circle gets from the equator is 47.4°N, 100% of the way along.

The heading barely moves: north out of Los Angeles, north into Seattle. Over this distance the curve has too little room to bend the compass.
