For scheduled operators from UK provincial airports, Jersey was a popular point because it fitted in well opposite their normal peaks of morning/evening weekday business travellers to Glasgow/Belfast etc. Early morning round trip from say East Midlands to Glasgow and back, then a midday Jersey, then evening to Glasgow again. Saturdays, when business travel was zilch, two or (in August) three Jerseys. Such utilisation can be seen from the 1960s to today.
