Three major GDSs and a number of travel management companies (TMCs) have agreed to take up common technology, in a bid to simplify the sale of airline ancillary services.
The technology will help airlines introduce unbundled fares on to the GDSs, and demonstrate exactly what is and isn't included in a bundled fare.
Philippe Chérèque, executive vice president, commercial for Amadeus, said: "It is a great achievement to have all these parties endorse the best way forward for the travel industry. We believe supporting these technology standards will benefit everyone in the travel value chain, from providers to travelers.
"Airlines will be able to differentiate their ancillary services offer and market it more effectively through travel agencies and to consumers."
American Express Business Travel, BCD Travel, Carlson Wagonlit Travel, Despegar, Expedia, Egencia, HRG, Opodo, Orbitz, Orbitz for Business, Travelocity, Travelocity Business, Amadeus, Sabre Travel Network and Travelport have agreed to support common technology approaches.
Yannis Karmis, president of Travelocity Business, said: "In business travel, lack of visibility into ancillary fees is not just a challenge for the traveler, but also the corporation that tracks and manages the total cost of each trip.
"A universally-recognized set of programs, delivering an accurate measurement of overall value for selling, tracking and accounting for ancillaries would offer transparency."
Airlines British Airways, Delta Air Lines, LAN and WestJet have also said they support the development.
Jim Cron, Delta's SVP global sales and distribution, said: "Delta supports this development of technology that facilitates the potential distribution of new ancillary products and services.
"We are continuously seeking distribution methods that satisfy the marketplace, and this technology is an option we are considering. It is important that we work with our agency partners to find the best possible solutions for our customers."
The industry-wide technology standards will enable shopping, booking, payment and reporting of ancillary services.
