That would depend upon the route. If you flew from San Francisco to New York that could be the Great Basin Desert. If you flew from Los Angeles to Miami you would probably fly over the Mojave, Sonoran and Chihuahuan Deserts.
They are the same distance, but it depends on headwinds and other contributing factors. Generally the jet stream which goes over the US from west to east makes the trip going east shorter. Of course, trafic or stops are not considerd.
From CPH, the plane usually travels west over the UK, continuing west over the Atlantic Ocean, passing just underneath Greenland. As you approach the coast of Newfoundland (Canada), you turn into a southerly direction, heading along the east coast of Canada and following that path down the east coast of the US until you reach Atlanta. This flight path is similar to the ones from CPH to IAD and EWR.
It would fly over Ireland, heading northwest, then over the north of the Atlantic Ocean, coming in towards Newfoundland in Canada and then down the east coast of the United States towards Florida.
Oban is on Scotland's west coast and North Berwick is on Scotland's east coast. Berwick on Tweed is also on the east coast but is over the border in England.

If you want to find the shortest distance from the east coast to the west coast then Florida is considered an east coast state. It's only 1763 miles from the coast at Pensacola, Florida to San Diego.
