An interline price is a specially reduced fare offered by a cruise line, often to get last-minute help with filling up ships that have significant space left onboard in the weeks just prior to the sailing date. These rates are provided via KVI primarily to travel industry partners (airline employees/retirees) and often also to employees of courier companies and the military. In many cases these rates can be extended to family and friends of interliners as well.
Interliners qualify for 1, 2, or more cabins at the interline rates, regardless of who else is traveling, as long as the interliner or an immediate family member is one of the travelers. Each cruise line has a specific set of eligibility rules. Please see below if you would like to read their specific interline rate eligibility rules.
