Well for a start how about making transfer passengers pay APD tax so they actually contribute something to the UK economy rather than just the bottom line of a few network airlines ?
Well existing levels of APD are in the opinion of many already damaging the UK economy, this proposal just makes this worse by putting BA at a further disadvantage against foreign competition.
Can people who sneer at transfer passengers please remember that a large % of LHR direct flights are not viable without them and that if they go a very large number of blue collar men and women in low paid ramp and hotel type jobs will be lost to the economy. Unlike flight crew, they have fewer options, and believe me when I say commuting across London to Boris International surely isn't one of them.
