If you work for emirates do you still get housing allowance?for example if I lived in Manchester or London,United Kingdom.
Also can the housing allowance be used to pay off a mortgage for a house you have bought?
Emirates is based in Dubai.
You cannot live overseas and work for Emirates. Commuting is not an option and is not practical. It is also very risky since Emirates standby travel is very difficult to guarantee due to constantly high load factors (you get bumped for cargo weight too don't forget).
You can use the allowance to pay for a mortgage if you like but realistically you would need to rent in Dubai whilst paying towards your mortgage back home. The rents here will almost certainly take up most of your allowance.
You can choose to buy here but with that comes many risks and you should investigate everything thoroughly and with mature attitude before committing yourself to such a bond. You can't just walk away from debt in this country if you lose your job, lose your medical, resign or whatever.
