Weirdly both sided comment. There’s one nation acting erratically, disrespectful, and without an ounce of decorum. Then, there’s a nation that, instead of cowering in fear as it used to be, responds to clown behavior with humor. Which is probably for the best.
Flying doesn’t need as much infrastructure so that’s definitely a factor. I couldn’t find the cost per passenger kilometer to compare so I can only say that flying emits much more co2 than every other form of transportation. Since climate change is going to cost us a lot I’d say the cost of flying exceeds the costs of car resp. train infrastructure.
