Pretty sure airplanes are here to stay. However how they are used and who can afford to get on one will change. Development of high speed rail will cut down greatly on domestic flights in the future, and carbon tax (not unlike the "guzzler" tax you pay on an suv) will drive flight prices higher and higher. One of the reasons we are not going back to Negril this year is that we could not find a flight at a reasonable price. We have a hard time justifying a trip when the flights cost almost as much as the rest of the entire vacation. We can fly to Ireland cheaper. Hopefully the highspeed rail will start sooner than later. A cheap train ride to the coast where flights to JA are much cheaper is an idea we can live with. For the time being paying $350 a week for a room for two and $688 a person to fly there seems ridiculous to us.
