I would say that Aer Lingus 1-11s were used on most, if not all, European and on all UK routes from Dublin over their time in service with the carrier, though Aer Lingus's then network was limited by today's standards. Amsterdam, Brussels, Dusseldorf, Frankfurt and Zurich were amongst the scheduled destinations and places like Barcelona, Ibiza, Palma and Tarbes saw charter services. I also recall the type being used on a service from Belfast to Shannon (connecting with transatlantic services) amongst other non-Dublin routes.
