Awful idea here but let say you work for Cathay for a few years as SO then you find a company they will give you TR and FO job. They you work for a few years as FO for the experience. Can you return to Cathay and join the FO as you have hours or are you viewed as a traitor and get black listed and ignored? truly an awful idea but the idea of 7 plus year as SO is not a great prospect.
