Vertical comprises four travel brands including Instant Holidays and Instant Breaks, the group's tour operating divisions. These sit alongside Your Holiday Booking and Holiday Elite, the group's dedicated homeworking divisions.
Together, the four Vertical brands currently achieve a combined £110 million annual turnover. Advantage called the group "a significant and sizeable player in the UK travel sector".
Advantage said the move further strengthens its position "as a leading supporter of independent travel businesses, providing them with a one-step solution to compete effectively in today's dynamic travel landscape".
