Aer Lingus BAC1-11s. What routes did they perform ?
A niche fleet of just four identical aircraft for over twenty years. I'm sure Aer Lingus could have had more if they wanted but, evidently, four was the magic number. Initially, a little more than the Viscount 800 capacity-wise and then slotting in between the Viscount and the 737-200. The 1-11 turned up frequently at Leeds Bradford on the Dublin flights (along with the 737) and I believe was also used on the fifth freedom trips from Dublin to Copenhagen, Milan etc., staging through Manchester on the way. Aer Lingus must have been very satisfied with their four pocket rockets to have operated them for so long but I guess there was more to the fleet than what I've mentioned.
