I have had correspondence with Jetstar on this matter
they have advised me on two seperate occasions that they are merely complying with the policy outlkned in the Department of Regional Development and Transports web site.
Restrictions for inbound flights to Australia
They apologised for my inconvenience and gave me $100 voucher to shut me up.
Another contributor to this thread has been advised the same thing.
They only gave the other contributor $50 voucher.
Hopefully they will get sick of issuing vouchers and relax the policy.
I have also spoken to the Department of Regional Development and Transport to clarify the position. They confirmed that they are aware that JETSTAR is citing there website as the reason for not allowing duty free alcohol to be carried on board, and that there is no basis for them doing so.
If you have experienced this issue then why not make a complaint. Apathy will get us nowhere.
It is only if we can get numerous complaints to Jetstar that they may start to listen.
I have actually also lodged a complaint with JETSTAR on the basis that I have been given false and misleading information by the customer service manager. I have fully documented this to them. I await a reply.
