Amadeus enabled the "world's first" interline Electronic Miscellaneous Document, via a link between EgyptAir and Finnair.

EMD is the document standard that airlines and billing settlement plans have created to enable the sale of optional services or merchandizing. "The application of EMD to interline partnerships means that participating airlines can now facilitate payment for and delivery of ancillary services across their partnerships and alliances," according to Amadeus. "Amadeus estimates that up to 20 percent of air bookings made through its system are the result of interline partnerships, representing a huge opportunity for airlines to increase revenues through the sale of ancillary services via their partner carriers." With the interline connection, "customers can now buy ancillary services across interline flights, safe in the knowledge that the operating airline will know the service has been purchased. Previously, the only way the operating airline would know a customer had purchased an ancillary service, such as extra baggage allowance, was through a paper document provided by the traveler at the airport."
