I worked at Shannon Aerospace when it first opened and the rumours then were that either Swissair or Lufthansa were going to pull out. Highly unlikely due to the amount of dosh they would have to pay to the respective partners to get out, plus, they both get their heavy maint done there at half the cost of doing it at their own base! (All heavy stuff by the way, no line work)
Lovely part of the world to live, but if you are working 15hrs a day, 7 days a week..not much point really?
