Apologies if this is a duplicate post, ive searched but cant find a layman’s answer. Im taking first international trip March 30, AVL-ATL-AMS-IST. Selecting window seat on the ATL-AMS flight and wondered why routes to AMS from ATL take a much lower trajectory ( flightaware.com/live/flight/DAL7 … /EHAM/KATL ) takes a much different path. If one path is the shortest, why wouldnt they fly the same route both directions? Im sure there is a simple explanation, I assume related to the rotation of the Earth, but my brain doesnt want to grasp it.
