What does "MC" refer to in airline terminology?

In airline terminology, "MC" typically stands for Main Cabin. The Main Cabin is the area of the aircraft where the majority of passengers are seated and is distinct from the First Class and Business Class sections. This designation is important for understanding the different seating arrangements and service levels that airlines offer.

In this context, the Main Cabin often encompasses a variety of fare classes and amenities, generally providing passengers with basic services and comfort during their flight. Understanding the roles and designations of different cabin sections, like the Main Cabin, is essential for customer service representatives, flight attendants, and other airline personnel to better cater to passenger needs and expectations.

The other terms listed, while they may hold specific relevance in certain discussions about airline operations, do not align with the term "MC" in common industry usage related to passenger seating.
