There are several synonyms for the term "coach class" that are frequently used when referring to standard airline seating. These synonyms include economy class, standard class, and main cabin. Essentially, these terms all refer to the same type of seating option for passengers who are not flying in business or first class. While the specific amenities and seat configurations can vary depending on the airline, coach class typically offers basic seating with limited legroom, no or minimal recline, and a standard meal service. Despite these limitations, coach class remains a popular choice for many travelers looking to save money on airfare.
