A friend of mine corrected me on the school allowance issues. He correctly pointed out that the school allowance is subject to tax.
As the marginal tax from 160-320000 SGD is 17 % you will actually only be reimbursed by 16800- 17 % = 14000. Since the school fees are around 23000 for two children you will have to pay 1500 per month. School bus, uniforms, field trips and education material are on top of this so schools will probably cost you about 1800 per month on top of the 10000 I estimated for your monthly fixed expenses.
I personally know a guy who would be perfect for this job but since he has three children he can't afford to come.
Don't know how this is reimbursed in your current airline but it's easy to be misled when they say that school fees are covered.
Still a god job though. Too bad the remuneration is reduced every year. I wonder when the bottom is reached and they will do a revision of the T&C:s. Last one was made in January 2005.
