that work around will only be there for so long I would suggest rob, as other airlines/countries will add similar taxes/surcharges on long haul flights
The airlines don't want it - it reduces business. Different countries also have very different airport/departure regulations - some where the commercial operator sets the prices, some where the govt sets the prices, some where each airline negotiates its own (and check-in space).
I'm thinking that since it's not really achieving anything except some thinly veiled distance tax which wont reduce emissions one bit it'll eventually come to nothing. There are so many long-haul departure points within 2 hours of London a $200+ penalty will be too much incentive to fly elsewhere, and one which will be taken up gladly by some airports/countries.
