Over the long term, All these excessive forms of travel are going in the wrong direction. It's not even a matter of ethics or morality. Peak oil is here (Source: Nate Hagens, Shell, etc ~ all predicting less and less oil available). The ramifications are vast and transportation is only going to get increasingly expensive as the material standard of living declines over the next several decades and centuries. Even normal airplane travel will get increasingly expensive, and less and less available to the middle and upper class.

The future is cheaper more energy efficient forms of travel like bicycles, e-bikes, micromobility and dare i say, walking.
