AABC

AABC, or "Any Any B1 C1," is an airline industry term used in flight scheduling and ticket pricing. It refers to a specific fare structure where passengers can book flights with flexible departure and return dates, often within a certain timeframe. "Any Any" indicates that travelers have the freedom to choose various departure points without being restricted to a single airport. The "B1 C1" part typically refers to fare classes and ticket types. This system allows airlines to manage capacity while providing customers with flexibility in their travel plans.
