Ok, once again: Facts, please, facts...
SWU (SWISS European Airlines) starts at 4th year FO which is 70500CHF. (Check PPJN.com, accurate figures there)
Tax in Switzerland depends on where you life (different tax rates from village to village). Average tax rate in Switzerland is at 21%, but could be a lot higher OR lower (if you know where the rich and famous life, you're there...) Social contribution is at 6.05%, excl. pension, which depends on what you want to spend on it.
I believe - for once NO fact, just guessing - that SWU pays all the mandatory pension fund (which is the case at SWR), so you'd pay only the voluntary part of it, which is in turn tax deductible.
So: 70500 - ~26% = 4500CHF/mt after all, which equals right about the average income (before tax and socials!) in Switzerland. Depends on what outfit in your garage, lawn, bed...
