Well, I'm no spring chicken but I can honestly say I can't recall a more anti-aviation government than this one. At least, not since the Wilson administration of the late 1960's introduced the £25 per pax limit on the amount of currency that could be taken abroad (per year if my memory is right), which played a big part in the demise of British Eagle.
If the Dutch government (historically one of the world's greenest) can see the folly of what was a much lower rate of Dutch APD, and abolish it, then HMG should take note. I suspect the lingering influence of Zac Goldsmith here.
