Definition of YCAL Fare:


YCAL: A YCal is a contracted airfare between the State of CA and the airline directly.  A type of airfare available to State travelers, for business use only, through State contracts with specific airlines.  These unrestricted (subject to no restrictions or limits; no additional fees; fully refundable; flexible) YCAL fares offer last-seat availability (access to any seat or any number of seats on a plane). Fares are fully-refundable and may be used for travel in either direction of the city pair. 


  • Fares are valid only on the YCal Carrier.
  • Fares are valid only between specific city pairs included in the program.
  • There are no advance purchase requirements for State of California fares.  Reservations may be made at any time, YCal seats are not part of a special inventory or capacity controlled.
  • VCal, ECal, MCal and LCal seats are part of a special inventory and are capacity controlled (only a designated number of seats available on the aircraft).  These State fare types are slightly lower than the YCal airfare.
  • Tickets are fully refundable and changeable with no penalties.
  • YCal fares are one-way and round-trip (including tax). These fares can be used round-trip or point-to-point.  Fares can fluctuate a small amount due to added airline/airport surcharges.
