Budget airlines are low-cost carriers that offer affordable air travel by minimizing extra services and amenities. They often charge for additional options like checked baggage, seat selection, and in-flight meals, allowing passengers to pay only for what they need. This model makes flying accessible to a larger number of people. These airlines typically operate on a point-to-point route system, focusing on short-haul flights between popular destinations. Examples of budget airlines include Ryanair, EasyJet, and Southwest Airlines. By using secondary airports and maintaining a quick turnaround time, they can keep operational costs low and offer competitive fares.
