Air Passenger Duty should be scrapped altogether to stimulate job and tourism growth.
The demand from Ryanair to axe the tax comes ahead of the removal of the travel tax for all under-16 customers from tomorrow.
Ryanair urged chancellor George Osborne to follow the example of the Irish government, which abolished its air tax in April 2014.
This triggered a major boost in passenger numbers at all Irish airports in 2015, which was a year of record growth for Irish tourism, with annual traffic rising by 3.3 million to 29.8 million passengers.
As much as 70% of this growth was delivered by Ryanair – an extra 2.2 million passengers – adding more routes and flights, while bringing more high spending tourists to Ireland.
A Ryanair spokesman said: “The continuous growth and success of Irish tourism since the total removal of APD, which is being driven by Ryanair, offers compelling evidence for Chancellor Osborne to take the same course in the UK.
“While we acknowledge that the removal of APD for under-12s, and under-16s (from tomorrow), is a step in the right direction, we are again calling on the government to scrap this damaging tax for all in order to promote economic, jobs and tourism growth.”
The airline citied an independent PricewaterhouseCoopers study which found that the abolition of APD would yield 0.46% of the UK GDP in the first year and at least £16 billion within thee years while new flights and 60,000 new jobs would be created.
