What does "cost-conscious traffic" mean in the context? Competition between a major city airport and a secondary airport is becoming a common feature in Europe and, to an extent, in North America and elsewhere. Major city airports tend to be located within the city boundaries, and they are convenient for passengers. Until recently, they handled all or nearly all of the traffic for the city. In recent years, secondary airports, located at some distance from the city, have entered the market for airport services. These airports may have been small regional airports, or they may have been military airports. They are less convenient than the major airports, but they have been able to attract cost-conscious traffic by offering lower charges. These have particularly appealed to low-cost carriers (LCCs), whose passengers are price sensitive but willing to put up with inconvenience to save money. They also offer the LCC an opportunity to fly passengers to or from a city without entering head-to-head competition with full-service carriers.
