Low-cost airlines are budget-friendly carriers that offer lower fares compared to traditional airlines. They achieve this by minimizing operational costs, which often includes charging for extras like checked baggage, seat selection, and in-flight meals. This model allows travelers to pay only for the services they choose, making air travel more accessible to a wider audience. These airlines typically operate on a point-to-point route system, focusing on short-haul flights. Popular examples of low-cost airlines include Ryanair, EasyJet, and Southwest Airlines. By using secondary airports and maintaining a quick turnaround time, they can keep ticket prices low while still providing essential air travel services.
