Clarity has acquired fellow U.K. travel management company Ian Allan Travel, a specialist in the corporate, education and charity sectors with a 55-year pedigree. Clarity ranked 10th on the 2019 Buying Business Travel list of the U.K.'s 50 leading TMCs, based on its U.K. sales of 446 million British pounds in 2018. Ian Allan was 28th at 47 million British pounds. The acquisition is the latest in a recent flurry of consolidation in the U.K. TMC market. Reasons are thought to include a ready supply of venture capital cash, higher costs of maintaining competitiveness, globalization of customer demand, and travel industry changes like supplier consolidation, New Distribution Capability and shorter International Air Transport Association Billing and Settlement Plan remittance periods.
