It depends on where you live and what your financial situation is. If you are 55 and have limited retirement funds, starting at the bottom of the seniority list at a U.S. major will not make as much financial sense as working in China. If you are the same age and in Europe, where age discrimination is common, and legacy pilots are for the most part retiring at that age, your options will be very limited as well. There are a lot of jobs out there, yes, but whether those jobs make financial sense for a guy in his 50s is a different story.
