I totally agree with you but there's a question that should be asked when it comes to going on vacation all over the place (and from what I understand it's more common in the USA/English Canada to move very far for school and to take the plane multiple times a year to go see one's family)... It's simply unsustainable but people keep pointing at the rich with their private jet but when looking at the big picture, it's tourists that allow commercial flights companies to continuously increase the number of flights they offer...
