Don't be at all surprised if EK assists as many as possible to take the allowance, and then at some stage in the near future, they'll reduce it significantly.
Ask yourself, why would EK continue to pay above market rates when rents have dropped 40-50% percent? Once you're out, you're out..unable to move back to company accomodation unless there are exceptional circumstances.
I could see EK dropping the allowance by 20-30% in the coming months.
..but then I'm the eternal optimist.
The allowance works for some, but only in certain circumstances. I would certainly not commit myself to a mortgage or tenancy agreement that requires the current full amount to meet my commitments.
