Interesting topic
Just musing your point fairdealfrank, about the UK having so many connections to other countries' hubs - AMS, DuB especially. Amazing that the Government in the UK appears happy to strangle their own businesses with air tax while wilfully handing over good business to other grateful recipients outside the country.
Surely it would make some sense for treasury to super-tax passengers transferring outside the UK economy to foreign hubs and perhaps even use such increased revenues to offset the burden on air routes within the country?
Or is that barking logical?
