serious flyer Despite Phil calling me a 'naysayer' there are some for whom joining SQCargo is a good decision as a DEC. Your situation being current on a MD11 and about to lose your job is just that.
To be fair to SQ you get your Bank Guarantee money back provided you stay the 5 years from final line check so the cost is minimal just the loss of real interest and the setting up costs of around S$1600.
You should base your finances around 50 hrs per month and lot of positioning. If you have children of school age then you need to look closely at those costs which I personally have no idea as to what they currently are.If you need a car in Singapore because of school children then that will make a big dent in your finances.
Also of course I have no idea as to where your homebase is and how difficult it would be getting there on your vacation leave and for children and wife ( if any) to get back and forth as for them being confined to Singapore day in and day out can be a bit tedious.
