I fail to see any logic in the rant of this man... He argues that you shouldn't tax airlines, as that would be give others an unfair advantage. However everyone else is already taxed, only airlines are exempt for e.g. VAT and fuel duty???
And what exactly is the role of aviation (or does he mean LCCs?) in today's society that makes it so important and allows to dump lots of CO2 into the atmosphere? E.g. doubling the costs of all flights would be a major inconvenience, but most businesses would find ways to reduce the need for travel.
