Barrhead Travel has confirmed that two new stores will open in Leigh in Greater Manchester and Selby in North Yorkshire.
The stores are expected to open in the next few months.
The Scottish-headquartered agency chain is planning to open up to 100 new stores to its retail portfolio.
Five branches have already opened with another 15 expected to launch by end of March.
Leigh and Selby bring the total number of confirmed locations to 17 across the UK.
Barrhead Travel’s Doncaster store opened its doors on Saturday with six former Thomas Cook staff.

More than 100 former Thomas Cook employees have joined Barrhead since the travel group’s collapse last September.
Barrhead president Jacqueline Dobson said: “We are very pleased with the progress of our expansion. Looking at the branches we have opened, it’s clear that there is a genuine appetite for trusted travel experts in the local communities where we now have a presence.
“Our new stores are performing exceptionally well with a number of them already exceeding targets set – in some cases, over 100% of January’s target has already been achieved.
“We’ve taken an atypical approach to our expansion by recruiting our people before we confirm the premises. For us, the most important element of this expansion project is to find the right people who are talented and really passionate about what they do.
“Securing retail units, completing all the legalities and commissioning a refit takes time. In locations where store launches are still in progress, the teams have been busy reconnecting with their local communities by selling holidays through social media and pop-up shops. The uptake in towns where we have temporary pop-ups, while the finishing touches to the stores are being done, has been really amazing.”
