You will be paid the equivalent of a one-way economy airfare. It will be based on what a flight would have cost when booked in advance.
If you're covered under the Full Relocation Policy, Crown Management Services will organise this reimbursement. If you're covered under the Lump Sum Relocation Policy, the Relocation Co-ordinator in Human Resources will organise this reimbursement.
