Maersk also aimed at serving the inclusive tours charter market. To gain better access to the market, Maersk bought two travel agents in December 1971, Raffels Rejser and Bangs Rejser. To better target the charter market, Maersk Air bought five used Boeing 720Bs in 1973. This was followed up with purchasing Unisol in 1974 and the three were merged to form a new agency under the brand Unisol and 120,000 annual trips. After having lost 100 million Danish krone (DKK) by 1979, Unison was sold to Tjæreborg in 1980. A participating cause was Unisol's inability to profile itself in a market dominated by two high-profile, yet diametrical, owners.
