Last year, the firm announced that its second English outlet would open in Leicester this spring and Barrhead has now confirmed further expansion plans for the next two years.
This follows a successful first year for their Newcastle store, which opened in late 2015 as the first branded retail outlet in England.
More than 12 locations across the UK have been earmarked as part of the two-year growth strategy.
Two new call centres will also be opened to support growth in the travel group’s online offering.
Sharon Munro, chief executive of Barrhead Travel, said: “To support our growth strategy, we’ve launched a recruitment drive and are on the lookout for exceptional individuals with a passion for travel.”
“Our expansion plans this year alone will see us taking on up to 100 new employees, including modern apprentices, destination specialists across our branch network and a variety of non-sales roles, including marketing, web content and business development.”
Meanwhile, the company has reported a 20% rise in sales year-on-year for January and February.
The result comes after year-end performance in the last few months of 2016 showed a 24% year-on-year increase.
The agency chain has seen a 25% upswing in family holiday bookings, with a 25% rise in traditionally popular destinations such as Salou in Spain.
Top-selling destinations included Dubai (up 132%), New York (up 44%), Thailand (up 150%) and Vancouver (up 24%).
Munro said: “We are delighted with our performance so far this year and anticipate continued growth over the coming months.”
