The Los Angeles to Seattle route drawn as a great circle arc on a globe ## 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. Holding a single compass bearing the whole way would cover almost exactly the same ground, so on this route the flat map and the globe agree. 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. One economy seat on it is about 228 kg of CO₂e each way, counting non-CO₂ warming.
