As pointed out by Leanne Jet* international prices are advertised without taxes.
Check out a fare to Bali where taxes amount to around $300. This certainly changes the fare from cheap to no different to what was previously available.
$300 taxes on a short international flight is bullsh*t. Australian Airlines were not adding $300 to their fares.
Methinks Jet* are indulging in some imaginative advertising with these so called cheap fares. Why not advertise $50 tickets to Bali with a $500 tax.
It might get a few suckers in.
Its a bit like a service station advertising petrol for 70 cents a litre, plus taxes. Despite this the ACCC think this is OK. As long as its in the fine print its OK.
