No housing
Bacou, there is no housing under the new contract. It is a special allowance which is non- contractual, can be changed at the whim of the company, and which unlike housing allowance paid for rent is fully taxable. It just about makes up for the loss of travel allowance and CNY bonus.
85% of the local pilots rejected the opportunity recently to sign over to the new contract, they were to lose the contractual basis for overtime and hourly duty pay. That should tell you something.
I agree with hkfooey that it is worth coming for a while as a young single pilot to get a new type rating etc, but otherwise it is not a long term option. Many pilots are only here still because of the " golden handcuffs" of the old scheme which paid your mortgage, otherwise we'd be off back to where the skies are blue and not polluted.
Any 330 slots have to be advertised internally so with many ahead of you it will almost certainly be the 320.
