Sometimes it is a bit too easy to forget how much smaller modern technology has made our world. Modern air travel makes it feasible to travel halfway around the world for a holiday and modern communications makes it easy to socialize with people all over the world.
But this wasn’t always so.
To a very large extent, how far you can easily travel is strongly defined by your world’s society. It is not just the technology, but also the economics that have made air travel affordable for many people. Go back eighty years and it was definitely a luxury exercise.
