Director Gavin Morton, who has been with the business for 35 of those years, described the decision to close as "quite literally one of the most heartbreaking moments" of his life.
"Covid took much away from us," he said. "And while we came through the other side, three years of heavy travel restrictions and in many cases a loss of client confidence in travel left a financial burden that was becoming more and more difficult to manage."
He added: "The loyal clients, many of whom have become friends and helped create the relaxing and fun atmosphere in the office, will be something the team will miss in our day to day lives."
