Short-haul flights are a major source of aviation emissions, and I've seen many advocates push for bans on flights under 500 km, forcing travelers onto trains. But is that always feasible? I live in a region without high-speed rail, so a flight that takes an hour might become a 12-hour train journey. While the environmental impact is clear, what about the economic and time costs for individuals? Maybe the focus should be on making sustainable aviation fuels more affordable rather than restricting options. Should we prioritize reducing flights or improving alternatives?
