How do travel routes of today differ from the trade routes of classical era civilization

During the Classical Era, long-distance trade routes (Greece to China) were predominately land-based while some short-distance ones took place around Mediterranean and other seas (Egypt to Greece). Today's travel routes are very different as we have begun to use flight to get from point A to point B. Additionally, while the goal in the past was to connect Europe to Asia, today we seem more focused on connecting the Eastern Hemisphere with the Western Hemisphere and thus we look across the large oceans more so than was done in the Classical Era.

Not sure if it’s within 12 months, but you could talk about the spreading of alt-right hate speech and whether that is covered by the right of freedom of speech? or, cover how during the midterm elections in some states many native american populations were declined to vote because they didn’t have the proper id, despite being citizens? also, the death of that journalist last month, who spoke freely and reported about the saudi government and how corrupted it is and was killed because of that (lack of free press/speech). just some ideas for this prompt, i hope at least one of them : )
