You are correct about the Caledonian (and others) 707 fleet, and about Caledonian's Mediterranean IT charterers, but the latter were almost wholly on their One-Eleven 500s, which broadly (it varied by year) was one in Glasgow, one in Manchester, and the rest in Gatwick, flights often being shared between multiple holiday companies. The 707s, certainly in summer, were principally used on transatlantic charters, for which Caledonian were notably the market leaders, picking up business from both Britain and North America. There were likely a few 707 rotations to Tenerife etc, which were beyond normal One-Eleven range, but not a lot, and not a dedicated aircraft.
The Glasgow Caledonian One-Eleven sometimes operated out of Prestwick rather than Abbotsinch, for a reason I have never been able to put my finger on.
