We have /c/fuckcars but no /c/fuckplanes. Yet a lot of the same arguments apply. They cause air pollution (roughly double the amount per km traveled), noise pollution and they (airports) take up a lot of space near dense living areas. Sure, some places can practically only be visited by plane, just like some places can practically only be visited by car. But people don’t consider not having your holiday that far away or giving pushback on a busines trip that should have been an online meeting. Besides work-from-home being encouraged, work-from-home-country should be too.
Cars need to be discouraged in favor of busses, trams and trains. Planes nees to be discouraged in favor of high-speed trains, staycations and hopefully new alternatives like modern sailboats or electric planes.
Suppose the route is important too. I live in Portsmouth, so the ferry to France is right here and I think it is better than flying to France. But that is also a short flight.
Plus its a car ferry, so its mainly transporting cars with people as a bit of an extra. I suspect there is much more variation with sea travel compared to flight.
