There's two arguments for scrapping APD in NI, and it's important each is articulated clearly. From the statements given by airports and airlines it's clear that not everyone is singing from the same sheet.
1) NI residents depend on air travel as a necessity for domestic travel to a greater extent than people in England, Wales and Scotland.
2) NI is the only part of UK to have a land border with another EU country, and is very close to a major international airport in that country that has no APD.
Separating but articulating both points should make for a compelling argument to win folk over in Westminster.
I hope...
