Base fare

A base fare in commercial aviation is the price of a ticket without taxes, fees, or other surcharges. Depending on the airline and flight itinerary, additional charges might include

• taxes (Passenger Service Charge, Airport Security Charge, Passenger Ticket Tax, etc.),
• baggage fees,
• preferred seating fees,
• customs charges, and so on.

Typically, full-service carriers have more ancillaries included in their base fare, while low-cost carriers sell cheaper tickets with only a seat and a minimum carry-on included so that passengers purchase extras, adding on to the base fare.
