The tie-up will combine AC Group’s curated itineraries, transfers and experiences with Great Little Breaks’ established short-break and event-led packages, creating new product for agents and trade partners.
The partnership is now live and will see longer holidays across the UK, Ireland and France sold via Great Little Breaks’ distribution channels. Agents will be able to access new itineraries, "enhanced packages" and extended seasonal travel options.
Great Little Breaks, known for packaging rail, hotel and event experiences, will add fully serviced touring itineraries and transfer solutions, alongside a broader range of attractions and immersive experiences.
AC Group chief executive Rob Russell said the agreement gives the company access to a new domestic audience, while helping hotel and service partners drive business.
He said: "This partnership provides opportunities for our partners to reach a broader client base and extend the travel season. By working with Great Little Breaks, we can deliver memorable holidays across the UK, Ireland and France for the UK traveller while connecting with new audiences."
The move is also expected to increase average booking values through "greater product depth" and dynamic packaging capabilities.
Packages will include rail options such as the Caledonian Sleeper, integrated with added-value hotel stays, without increasing operational complexity for trade partners.
Diana Evans, managing director of Great Little Breaks, said the partnership marked "a significant step forward" for the business.
"We can move beyond traditional short breaks and provide richer, longer UK holidays and touring options, delivered with the same trusted service our customers expect."
