The purpose of this preference is to allow the client to control whether they offer their customers the option to search and book fares that include the air segment offered by the cruise line. The preference will exclude Cruise Line Air, Pre Cruise Air, and Post Cruise Air options. The preference is controllable at cruise line level and applies for both B2B and B2C searches.
Accepted values for this preference are * (for all cruise lines) or comma separated Cruise Line ID’s, ex. 1, 2 would exclude it for Carnival and Celebrity Cruises.
