The world has changed and the changes have caught up to the USA. It seems now we have to pay our "dues" by flying for regionals for low pay just to get a chance of landing at SWA, Alaska, FDX, or Delta. Everyone else pays squat wages. The competition among pilots to get a job at those four mentioned airlines will be intense like a Cowboys Redskins game.
There are some tax advantages of working overseas.
In many Mideast countries there are NO income taxes and I would say no union dues either. I would say do a present value calculation for all current and future income. One for the USA and one for an expat job. I am sure the expat job will get you a larger sum of money at the end of a career.
