If it might be of interest, here's the Airways International Cymru programme for Summer 1985 as constructed from that year's Airport Timetables UK publication. I'm not sure what leaves me more traumatised - the amount of positioning legs or the thought of trying to do Bristol-Athens on a Sunday night in a BAC1-11-300. Enjoy!
