Step-by-step explanation:
Typically, in the context of commercial air travel, there are three main types of seats offered in a cabin. These are usually classified as Economy, Business, and First Class seating. Economy class offers the most basic amenities and is the most affordable option.
Business class provides a higher level of comfort and service, often including larger seats and additional services. First Class represents the most luxurious option, featuring premium seating, fine dining, and often extra privacy. Airlines may name these categories differently or offer additional specialized classes, such as Premium Economy, but these three are the foundational categories.
