The Tories' plan is to replace VAT or fuel duty on domestic flights and air passenger duty (APD), which is to levied on airlines and costs and be between £10 and £80 per passenger, This will be replaced with a per-flight tax that will target airlines with the dirtiest engines. It also proposes an annual "green air miles allowance" that will allow travellers one short-haul flight a year (Does this count return ticketed flights?) at a low tax rate and charge frequent flyers a higher tax rate. Although this may be difficult to administrate.

But voters warn they are fiercely against any new "eco" taxes on airline travel. But the Tories are starting to sound like a bunch of loony left students with all this green nonsense. That's when they're not sounding like a wealthy London elite who want to stop ordinary people going on holiday. But it's highly unlikely that the Tory dissenters, who dislike the idea of Higher taxation, will publicly start to attack Cameron until after the May election. But then the sniping may well start, particularly after his other policy blunders such as the A-list and the like.
