Just out of curiosity when all of these Canadian services existed from the likes of EXT, CWL, ABZ and LBA were they catering to charter traffic going both ways (i..e Canadian travel agencies doing holidays in the UK and using various cities as start/end points and UK agencies serving multiple local markets) or was there really such high demand for people from Canada to these destinations?
The flights leaving the UK would presumably have been mainly holidaymakers going to Canada.
