The Titanic ocean liner, isn't a fable, or isn't just a movie, it was a real event, so back in the day, the rich and elite, in ordered to travel from England to New York city, went in style on an ocean liner, which took many days, and quite frankly, if it wasn't for those rich and elite losing their lives on the Titanic disaster, that story probably would have sunk beneath the waves today. So too, when the very first commercial air flights were made available from the east coast to European cities, these airliners, carried the rich and elite, to the exclusion of everyone else, because the price was so steep as well as the passenger section being so small, in which, the biggest advantage of such air travel, was the great savings in time, so that those that traveled by air, could be about their business of living the good life in European hot spots, enjoying their haute cuisine and the sights, while those that still traveled the old school way by sea, were in the middle of an endlessly blue ocean.
The events of World War II, took aircraft, its reliability and its cost structure to a whole new level, so by the time that war was over, there existed a real opportunity for the manufacturers of aircraft to deliberately commercialize such and make them available for transatlantic travel, in which, the United States, led the world, in producing such, because the European nations, were in the process of rebuilding their infrastructure after the destructiveness of a devastating World War. This meant that in the 1950s, the first commercial airliners were born, which while still favoring the rich and elite by providing them with the proper first class comfort and pampering that they gravitated to, also provided a more common class of seating for those that simply wanted to get to their destination through the convenience of air travel.
Today, with so many airlines throughout the world, and the multitude and variety of aircraft that are built by major players such as Boeing and Airbus, along with the general deregulation of airfare and air travel, the cost of transatlantic travel has dropped to new lows, so that just about anybody with access to some sort of credit, can simply board a plane and within just a few hours leave domestic America and arrive in international places of interest in Europe or just about anywhere, whereas the ocean liners of yesterday, that crossed that same Atlantic ocean, simply don't exist as a viable means of passenger transportation, because people appreciate the convenience, safety, and cost effectiveness of arriving at their destination in so quick of time.
This means, never has the world appeared so small to so many, and additionally never has it been easier for people of different nationalities to travel to countries dissimilar to their selves, which is quite beneficial because the more that we learn firsthand about others, the easier it is to see them as in essence, being common to ourselves, brothers and sisters of meaningful cultures that interest and intrigue us, having children and schools, and aspirations that echo our own experience, which leads to more understanding and empathy for others, and a worldview that trends to seeing a true universal brotherhood of mankind.
