Big move? Well what do you have to loose? You are an FO mid 30' with relatively low hours. Pension? there is NONE, even at EK, it is just a provident fund at end of service. QR or EY, same deal, I think QR is the better choice. If you have a job in Europe, I would recommend to stay there unless it goes bankrupt. If desperate take what they give you, you won't have a choice, take what you are offered. Good luck.
