The Internet has not made travel obsolete. Despite the eventual ability to make high quality video "phone" calls as often as we make voice calls today, the need to travel for business is not going away.
Three trends are converging that could be very good news for rural regions that are far-sighted enough to take advantage of them.
Rural regions of the country that have invested in smaller, regional airports (smaller than what the commercial airlines will use) will have a key economic development advantage in the Knowledge Economy. Commercial flights are beginning to nudge $800 to $1000 for business travel, because it is usually difficult to schedule travel weeks in advance to take advantage of bargain fares.
At those price points, air taxi service begins to look attractive, especially if you can save a full day of meals and an overnight stay. Time is also money, and point to point nonstop air taxi flights can save many wasted hours of travel time. Rural regions that have both affordable broadband AND a well run and well maintained small airport with air taxi service will have a hard to beat competitive advantage.
Here in the New River Valley, communities are debating whether we need one or two small, local airports (they are located about 30 minutes apart). Both serve important business and economic development needs, and both should be maintained and improved. In the end, it is all about attracting new businesses and keeping the ones you have. Small airports are going to become more important than excess water and sewer capacity, and at least as important as high performance, open access digital road systems.
