Airlines traditionally have three travel classes, First Class, Business Class, and Economy Class. Depending on the cabin configuration will determine how many classes of service are offered. Here’s a breakdown of the classes of service:

• First Class, generally the most expensive and most comfortable accommodations available.

• Business Class, high quality, traditionally purchased by business travelers (sometimes called executive class)

• Premium Economy, slightly better Economy Class seating (greater distance between rows of seats; the seats themselves may or may not be wider than regular economy class)

• Economy Class (also known as coach class or travel class), basic accommodation, commonly purchased by leisure travelers
