# How does Combo Fare work?

Combo Fare works by allowing you to select flights with two different airlines for your round-trip journey. ShareTrip’s system automatically finds and combines the lowest fares available, letting you book both flights in a single transaction. This eliminates the need to manually search for the best fares on different airlines.
