In that case I guess a lot of the people on here complaining will have to reclasify themeselves as either;
a) those who desperately need a seat & are thus willing to pay whatever price is needed, OR
b) those who are clamouring for cheap seats only, and aren't prepared to pay the premium the market commands.
So - if the additional aircraft aren't full then I can only assume that a lot of the venting by the Tasmanian public was just a lot of hot air...
