Step-by-step explanation:
Airlines sell customers in different levels of service by offering various fare classes or ticket types. These classes typically include Economy, Business, and First Class. Each class offers different benefits and amenities, such as seat selection, priority boarding, free checked bags, and access to airport lounges. The prices for these classes vary, with First Class being the most expensive and Economy Class being the least expensive.
For example, a customer who chooses Economy Class may have limited seat selection options and may need to pay for checked bags, while a customer who chooses Business Class may have more comfortable seating, priority boarding, and free checked bags. Airlines use these different levels of service to cater to customers with different preferences and budgets.
In addition to fare classes, airlines may also offer add-ons or upgrades, such as extra legroom seats, Wi-Fi access, and premium meals, for an additional fee. These options provide customers with the opportunity to enhance their travel experience beyond the standard service offered in their chosen fare class.
