Towards the oceans. The great plains are in the center of the North American continent and the coastal planes are East, West and South nearer to the oceans and seas.

As you travel from east to west across the United States, you encounter distinct physical regions. Starting in the east, you have the Appalachian Mountains, followed by the rolling hills and plains of the Interior Lowlands. Moving further west, you reach the Great Plains, characterized by vast grasslands, before transitioning into the Rocky Mountains. Finally, as you approach the West Coast, you'll find the diverse landscapes of the Pacific Coast, including coastal ranges and valleys.
To travel from Ivory Coast to Chad, you would generally head northeast. This route takes you across several countries in West and Central Africa, including Burkina Faso and Niger, before reaching Chad. The specific direction may vary slightly depending on your starting point in Ivory Coast and the chosen travel route.
If you were to fly from San Francisco, California, to Miami, Florida, you would generally travel in a southeast direction. This trajectory takes you across the continental United States, moving from the western coast towards the southeastern region. The flight path may vary slightly based on air traffic and weather conditions, but southeast is the primary intermediate direction.
Coriolis effect
Galway is on the west coast and Dublin is on the east coast. So if you are travelling from Galway to Dublin you would travel east.

Because it is exposed to incoming Atlantic storms which travel in an Easterly direction.
New York is on the east coast of the United States. California is on the west coast. Travelling from New York to California you would travel west.
Coastal Plains
I don't really know the air route.But it is rationale to travel west then reach the eastern areas of Russia(eg_Vladivastoc).In fact territorially USA is very close to Russia on western and eastern coast near the pole.
