<bot>: The main difference between a low cost airline and a legacy airline is the cost of the tickets. Low cost carriers typically offer lower fares than legacy carriers, but may have additional charges for amenities, such as baggage fees, seat selection fees, etc. Low cost airlines typically do not offer full-service amenities, such as complimentary meals or beverages, compared to legacy carriers. Low cost airlines also tend to have fewer direct flights and may require more overall travel time than legacy carriers.
