Air flight = traveling to the furthest corners of the world. It equals the most exotic, extreme, and enticing getaways.
Without air flight there would be no domestic flights but also no transatlantic trips meaning that the ground-based ways of traveling - train, bus, car, even horse, donkey, and camel - would remain our only option and travel would, as a result, be hundreds of times slower.
Air flight has changed the fact of travel, essentially. Although the ‘slow travel’ movement eschews flying, and those who wish to minimize their carbon footprint do, too, without this fast and very convenient mode our world would be far less interesting and available to fewer people.
A one week vacation would mean staying within one’s local vicinity; and travel broadens the mind, as I’m sure you will agree. Our minds, as well as experience, would be less without it.
