Air travel prices may have gone down over the last several years, but so has what you are paying for. There was a time when you could expect leg room, a drink and at least one pack of snacks on any flight that you might need to take. Today you are lucky if you actually end up getting a flight at all, much less getting amenities along the way.
Airlines are now in a position where they have to compete with easier travel systems than there was just a couple decades back. Interstates, better cars, and even the resurgence of train travel have all made getting there easier. People are more mobile today. Because of the competition and the mobility of the consumer, air travel prices have continued to drop.
Unfortunately for many companies in the air travel industry, the cost for maintaining the airlines has continued to rise. Fuel prices sore, labor costs (through salaries and benefits demanded by labor unions) and even amenities seem to increase on a daily basis. To make matters worse, the Federal Government has stepped in to "fix" the situation instead of letting the market fix itself.
Air travel prices may be looking at an increase in the future. As consumers demand more amenities for their money and the market tries to correct the discrepancies that currently exist, a price increase will likely be necessary. The result will be a much more competitive market that will drive many companies out of the industry.
It the Government can keep out of the airline industry, eventually the air travel prices will regulate themselves. Basic economics says that demand and price are interrelated. The airline companies that will be truly successful in the industry will be the ones that can offer the most bang for their air travel prices.
