Magenta, unsure from your post if you're referring to salaries at CX, or in the US. In case it's the US:
None of the majors require 401(k) deductions - it's straight direct contribution (by the company), typically 16%. Kinda like the old 15.5% Cathay DC.
Federal Income Tax is around 24%. State income tax varies by state. Mine is zero.
About 60% of pilots in my airline commute. ID travel/jumpseats are free. Including on other airlines. Very doable.
