Better yet, proffer all your work away and lie on a beach. Lets say you are a relief FO on SFO1 based in HKG. Proffer 84 hours away for $42K. Pay 16% tax on your $70K salary and you are left with $17K a month for doing nothing. Just make sure you use the home purchase allowance to make some financial headway. You could easily take up full time work somewhere else on the planet;-)
You might want to come to HKG every few months for landing recency though;-)
