Newcastle airport has issued a fresh plea to the new government by calling for a national system of Air Passenger Duty.
Westminster is being urged to announce specific measures to support English regional airports from the impact of APD devolution to Scotland.
Newcastle airport says the government should undertake to at least match any reductions in Scotland across the rest of the country.
Scotland has introduced an Air Departure Tax Bill as a replacement for APD and is committed to reducing the tax from next year.
The largest airport in the north east pointed out that politicians and political parties from various parts of the UK, including Northern Ireland, are in favour of abolishing APD.
Chief executive Nick Jones said: “The issue of APD is a particular concern for airports in northern England, as the devolved Scottish government has been given the authority to reform and reduce the burden of APD north of the border.
“We also recognise that it is an issue for airports in Northern Ireland.
“Given the impact of changes to APD in Scotland on both the Airport and the north-east economy is so great, we would urge the government to agree a national solution.
“That way, we’ve got a fair system without market distortions and a level playing field throughout the UK.”
