Caledonian Airways built up quite a 707 fleet from the mid-1960s onwards, taking over from their Britannias, and their principal usage was summer Transatlantic IT charters, where they became a market leader. There were just a few Mediterranean IT flights which were beyond the capabilities of their One-Elevens, and off-season they found various tasks, including a substantial programme to Singapore. Come the merger in 1971 with British United and they started to run this non-scheduled side slowly down, and the 707s were progressively transferred to what the BUA VC-10s had once done. The 707 fleet rose (sometimes) and fell, dependent on what work they secured, I don't think they ever quite got it into double figures, and had a long handover period to the DC-10; the first of these came in charter configuration as well for the initial year, but that side of the business was just progressively dropped off.
