Singapore COL
I just came back last month after an interview with SIA for a 777 instructor's job. I have retired from a major in the States and am beyond their cockpit age. My wife and I were very pleased with the accomodations we saw. Lots of ex-pats and they advertise and give lots of advice on the web. Do a 'Google' search for Singapore furnished rentals and you will get an idea. Are you going to be a cockpit crew member or a retired instructor? Are you inquring of SIA? There are 2 different Housing Allowances with the line pilots getting quite a lot more. Ex-pat instructors have a S$2,000/mo perk which in my case will easily cover a nice 2 bedroom place in a nice area plus all my living expenses for the month. Really. Taxes are roughly 12% and the direct responsibility of the wage earner. No withholding. Have you been lately? Changes afoot at SIA with a new contract being forced down their throats. Not pleasant but my airline is trying to go after my retirement pension after 35 years so I will need the job.
Good luck.
