Despite a London-Berne service being featured on Autair's Timetable for Winter 1967/68 I cannot remember such a service operating. No mention of Berne on Autair's Summer 1968 Timetable. Perhaps they were hoping to start a winter service for Skiers. They certainly operated a series of ski-holiday charter flights roundabout that time using the HS748s and flying from Luton to Zurich. Still it's a long time ago and I could well be wrong!
