What is this Swiss European contract like? I know that there is only the PAS Aviation (based in Rotkreuz, Switzerland) contract for experienced FO. You will stay there for maximum a few years and then be replaced by the ab initio guys, who get started now. So you will find yourself without job in 2 or 3 years. You will not be part of the seniority list and have no right for upgrading.
Cathay is SFO (Senior FO, not Second Officer), right? This is a real career. Longhaul might be boring, but short haul (especially SWU) is very tight, they fly their b*tts of, that's why everyone is leaving. In Cathay you fly 2 or 3 times per month, the rest is off. Are you RJ rated already?
PM if you need more info.
