Flex Fares are new multilateral interline fares derived from published carrier fares. The concept is simple: for a given market, a base fare is calculated using available carrier fares in the market, and an interline premium is added which reflects the flexibility in an IATA fare.

Key Benefits

• Fares are driven by and linked to market prices
• Consumers enjoy the flexibility of interlining and conditions
• The combination with the e-Tariffs process  saves participating airlines time and expense.
