There will always be a need for air travel for long distance and
overseas journeys. I recently saw a note that traditionally in Europe
trains were competitive with air travel for trips up to three hours.
However with slower ground handling for flights, the break even point
was approaching 4 1/2 hours (which can mean trips up to 450 miles in
Europe).
Another competitor to air travel is video conferencing.
The equipment has much improved and the process could replace some
business travel.
