When I was a student and wanted to visit a cryptographic workshop in 2004, I traveled Prague to Barcelona and back for, then, some 700 eur. That was by far the cheapest option, bought months in advance. Looking at the options now, 200 eur is very doable, although there will be extra fees for luggage. But there have been almost 20 years in between! In 2004, 700 eur must have been around the average net monthly salary in CZ; now, the average net salary is almost twice as high. So, from a purchasing power point of view, costs of flying have gone down about 7x for a Czech person, in mere 19 years.
