2007 is proving to be a busy year for new, low cost airlines around the world. In the United States, two of the most recent low cost carriers to enter the air travel arena have had much different routes to starting up.
Skybus launched itself as a low cost contender by advertising $10 airfares that would be available on all of its flights. Seats at that price are of course limited, but it is an airfare special that is not set to expire anytime soon.
Virgin America has had a different experience. It has had to fight past objections by several airlines regarding ownership, and a few years later, has been able to secure FAA approval.
