Class of Service (COS)
What is Class of Service (COS)?
Class of Service (COS) is a classification system used by airlines to differentiate seating options based on fare, service quality, and passenger experience. Common COS categories include Economy, Premium Economy, Business Class, and First Class, each offering varying levels of comfort, legroom, and in-flight benefits.
Corporate travel policies often define the allowed Class of Service based on employee rank, budget constraints, and travel distance. For example, executives may be permitted to book Business Class for international travel, while other employees are restricted to Economy Class.
Selecting the right COS impacts travel costs, employee comfort, and policy compliance. Many companies use travel management platforms to automate COS selection according to corporate guidelines, ensuring both cost savings and employee satisfaction.
