The issue is whether aviation is being unfairly targeted - personally I think it is - I couldn't give a damn what % of GDP our taxes are set at - all I object to is having to pay these increased taxes when I want to see my relatives in Australia.
Also our politicians are lying (how unusual?) when they tell us this is a "green" tax when none of it is being set aside for "green" purposes (whatever they are).
At a time when the UK airlines are having enough difficulty making profits, HMG decides to increase taxation on air travel.
When the next election comes round and I get canvassed on the doorstep by the prospective parliamentary candidates I will be asking them what their views are and which way they voted - if they indicate their lack of support for changing this penal level of taxation on aviation I will be making it blatantly clear to them that they will not be attracting my vote and I will be educating others to do likewise.
