Duffel

Airline ancillaries on Duffel offers and Duffel orders: seats and bags. Duffel's service types for this are seat and baggage. This shelf does not call Duffel offer search. Job: Seat or bag beside the ticket. A map or a bag list is not a confirmed extra. Adding it runs only after an explicit yes, and the payment has to include the service price the supplier just returned.

Your own key always wins, and Ancilair does not meter those calls. The price of a call on Ancilair's account is quoted on the call, with 0% markup.
