Airline policy refers to the set of rules and guidelines established by an airline to govern various aspects of its operations. This includes ticketing, baggage allowances, cancellations, and refunds. Each airline, such as Delta Air Lines or American Airlines, has its own specific policies that can vary widely, affecting how passengers plan their travel. Additionally, airline policies often address customer service procedures, frequent flyer programs, and safety regulations. These policies are designed to ensure a smooth travel experience while also protecting the airline's interests. Passengers are encouraged to review these policies before booking to avoid any surprises during their journey.
