There is no moral justification to tax aviation, as all of its infrastructure costs are recovered by other means. The only justifiable tax is an equivalent of VAT, but as other countries do not do this, it would be unwarranted on UK aviation.
Fuel tax on road transport is logical (albeit excessive) as a proxy for motorists paying for the long run costs of building/maintaining the road network.
Aviation doesn’t have this issue, so the appropriate response is for this tax to be frozen, and then abolished when there are sustained budget surpluses. It exists as an envy tax to penalise those who fly, it’s banal at treating any travel other than economy as “premium” so those who fly premium economy pay the same as first class.
