What is Interline?

Interline travel benefits are often available for employees, spouse, parents, dependent children and retirees of the airlines.  Interline travel discounts on other travel industry suppliers varies by supplier and travel time. Interline discounts on cruises and hotels can be booked through interline travel agencies. To qualify the traveler must provide proof of eligibility, such as a copy of their airline ID badge or letter of employment on airline letterhead. Only a handful of fully qualified interline travel agencies, mostly in North America, provide interline services.
