Sailing either due north, due south or due east from Ono Island, Alabama, the first land you encounter is in Florida.

*- Here by sailing West I mean point the ship westward and do not change direction
Is that due to ocean currents?

Atlanta (the Metro area) is the sprawliest city not only in America, but in the world. If there are any cities tied with it, they would be Nashville and/or Charlotte, Raleigh. Even Houston looks compact compared to Atlanta.

Atlanta has slightly less than one-third of Los Angeles' metropolitan population, but it takes up 33% more land.

The Florida Panhandle once extended all the way to Baton Rouge.

No, I didn't take the currents into account.

In short, it's because as soon as you start moving, you'll be going further and further South. The easiest way to see it is using azimuthal projections. You can roughly see it here:

I do see your point, and it is a fine example of how conventional projections limit our ability to perceive the Earth as it actually is arranged.
You original instruction was to sail West (270*) from the Northern tip of Norway. That just sends you on a circle around the Arctic Ocean. You actual point, that one can sail from Norway to South America in a direct line, without crossing a major land mass, is very interesting.

Again, not quite. In order to circle around the Arctic Ocean at the same latitude you need to maintain westerly heading, which actually means turning a bit to the right every so often. If you don't turn, you'll go along the same azimuth, sailing like so:

"Sailing West" means to take a heading of 270* from wherever you are. In a spherical world this will cause you to circle the north pole until you return to your starting point.

Is that because "cities" i.e., MSAs, are defined by county boundaries, not actual urbanization? For example, the Riverside/San Bernardino CA metro area encompasses not just hundreds or cities, towns, suburbs, but huge areas of virtually unpopulated desert, and the Duluth/Superior MN/WI metro area encompasses huge areas of virtually unpopulated forest ares, including the Boundary Waters Canoe Area.

Alaska is directly in-between Australia and the Eastern United States.
