• Within Offers (excluding a-la-carte Offers), there should always be at least one OfferItem marked with the MandatoryInd=true. Absence of this element implies the OfferItem is optional (same as using MandatoryInd=false).

• When defining rules regarding baggage allowance, the TotalMaximumWeightMeasure element should also be populated (e.g. https://retailing.iata.org/tools/xsd_viewer/21.3.4/IATA_AirShoppingRS/?xpath=%2FIATA_AirShoppingRS%2FResponse%2FDataLists%2FBaggageAllowanceList%2FBaggageAllowance%2FWeightAllowance%2FTotalMaximumWeightMeasure).

• Total Price at Offer-level should not be used in shopping responses (e.g. https://retailing.iata.org/tools/xsd_viewer/21.3.4/IATA_AirShoppingRS/?xpath=%2FIATA_AirShoppingRS%2FResponse%2FOffersGroup%2FCarrierOffers%2FOffer%2FTotalPrice or https://retailing.iata.org/tools/xsd_viewer/21.3.4/IATA_OrderReshopRS/?xpath=%2FIATA_OrderReshopRS%2FResponse%2FReshopResults%2FReshopOffers%2FOffer%2FTotalPrice).

• There are two elements where birthdate is mentioned in Datalists:

  • /IATA_AirShoppingRQ/Request/PaxList/Pax/Birthdate and

  • /IATA_AirShoppingRQ/Request/PaxList/Pax/Individual/Birthdate

  The first element is to be used only in case of anonymous shopping, while the latter is to be used once the passenger data is communicated.

  The same rules apply to the elements

  • /IATA_AirShoppingRQ/Request/PaxList/Pax/CitizenshipCountryCode and

  • /IATA_AirShoppingRQ/Request/PaxList/Pax/IdentityDoc/CitizenshipCountryCode

• In servicing scenarios where a price differential is returned (following the replacing or removal of an existing OrderItem), the PriceDifferential structure needs to be persisted in the OrderViewRS until payment is fully allocated to those affected OrderItems.The DueByAirlineAmount and DueToAirlineAmount elements within the OrderViewRS’s PriceDifferential structure should only be present if there are any outstanding amounts to be paid or refunded.

• Delivery Status elements should always be present in OrderViewRS (https://retailing.iata.org/tools/xsd_viewer/21.3.4/IATA_OrderViewRS/?xpath=%2FIATA_OrderViewRS%2FResponse%2FOrder%2FOrderItem%2FService%2FDeliveryStatusCode).

  • Unpaid OrderItems: DeliveryStatusCode=”CONFIRMED”.

  • Paid OrderItems: DeliveryStatusCode=”READY TO PROCEED”.

  • Cancelled OrderItems: DeliveryStatusCode=”REMOVED”.

  • Reference the ATSB Codeset Directory (codeset DELIVERYSERVICE) for all available Delivery Status Codes.
