The initiative is part of a wider drive to boost product sales through the Lastminute.com-owned site.
Agents will be able to access the website through the MySabre homepage and dynamically package individual components including air tickets, hotels and car hire.
It is hoped the move will spearhead wider use of the service among the agency community and is a long term goal of Holidayandmore.com general manager James Eustace, who expects the number of agents using the site to increase by between 10% and 20%
STN UK vice president Reet Wiseman said: “Through having a presence in every channel of distribution we offer travel providers so much more than the single option of distributing their products through the travel agency channel.
“This efficient marketplace results in our being able to negotiate the fullest possible range of fares and content for our agency customers, at the best possible rates.”
