Taxing the industry to death
If the government continues to tax the industry to death it, which it will do eventually, is this a cunning plan so not many people travel abroad but spend their money in the UK ! The amount spent on holidays abroad would be spent in the UK by the low earners and the big earners just pay a shed load more indirect tax.
A family of five travelling to Florida pay £1000 in tax before fuel charges (why is this still being charged?) then they have the price of the ticket. The industry is going to go backwards quickly in this country. If you want to fly you will need to relocate.
