Wait, where does this happen? The airline industry seems to have a high degree of competition and very good pricing for consumers. Which makes sense given that it isn't an industry conducive to natural monopolies. The cost to open a route isn't that high compared to the cost to operate the route, and the cost of operation scales with revenue from the route; there isn't much in the way of fixed capital required for a route.
