This referral list allows the merchant to make, block, and trust lists based on the legs being flown on an itinerary. Note that the use of this check requires submission of airline-specific data in the payment request.
- Merchants are able to submit legs individually, utilizing the IATA format.
- Each leg can be given a specific scoring, negative to give it a trust value and positive to give it a block value.
- Each leg must be quantified explicitly. For example, if a merchant established a rule for AMS to JFK. A separate rule would also need to be created for JFK to AMS.
