The British Government has confirmed it will not exempt the planned Derry-Dublin air service from Air Passenger Duty, prompting sharp criticism from Northern Ireland’s Economy Minister who warns the tax could undermine the route’s viability before it even takes off.
Dr Caoimhe Archibald expressed disappointment at the decision, which comes despite Whitehall acknowledging the strategic importance of the connection for the North West. The route, funded by the Irish Government under a Public Service Obligation scheme, is intended to restore a link lost when the previous service closed in 2011.
What is being proposed
The twice-daily service between City of Derry Airport and Dublin Airport is scheduled to commence in late 2026, with October previously cited as a target date. The Irish Government has committed €2 million from its Shared Island Fund to establish the route, which operated successfully for a decade until its withdrawal 15 years ago.
Key details about the planned service:
- Funding: Irish Government Public Service Obligation (PSO) scheme
- Frequency: Twice daily
- Proposed start: Late 2026 (originally October)
- Previous operation: 2001–2011
- Stormont investment: £4 million annually in City of Derry Airport development
However, significant uncertainty remains. No airline operator has yet been appointed for the route, and the tender process—complicated by Brexit-related regulatory issues—is still pending. The Irish Department of Transport has stated it anticipates publishing a Request for Tenders “very shortly,” with services to begin “as soon as operationally feasible.”
The APD dispute explained
Air Passenger Duty is a UK tax levied on passengers departing from British airports. From April 2026, domestic flights within the UK attract a reduced rate of £8 in economy and £16 in higher classes, while short-haul international flights to Band A destinations (including the Republic of Ireland) carry rates of £15 and £32 respectively.
The core of Minister Archibald’s objection lies in a disparity of treatment. The existing Derry-Heathrow PSO route, funded by the UK Government, is exempt from APD. As a UK Government spokesperson explained: “APD-free PSO routes are designed to support connectivity within the UK and so can only start and end in the UK.” The Derry-Dublin route, however, terminates in the Republic of Ireland—outside the UK tax system—meaning the exemption does not apply.
Minister Archibald’s response
Dr Archibald issued a strongly worded statement:
“I am disappointed that the British Government has doubled down on its refusal to exempt the Derry-Dublin air service from Air Passenger Duty.
“Passenger numbers at the City of Derry Airport have grown strongly over the last few years. The Derry-Dublin route is another step forward in the airport’s development and the New Decade, New Approach agreement committed the Irish and British Governments to work together on the route. Yet the British Government is imposing a tax which potentially undermines the viability of the route.”
She continued:
“This is a strategically important connection that can strengthen economic opportunities in the North West, improve international access through Dublin Airport, enhance tourism and support regional balance.
“This decision also reinforces the need for a fresh look at APD in the north. As an island air access is vital, the tax does not apply in the south. People in the north should not be penalised by an unnecessary barrier to attracting investment and creating opportunities for businesses, and which adds costs for workers and families.
“I will continue to press the British Government to reconsider its position and demonstrate through actions, not just words, its commitment to regional growth and prosperity.”
Context and omissions
The Minister’s claim that “the tax does not apply in the south” requires clarification. While the Republic of Ireland does not operate Air Passenger Duty, it does levy its own Air Travel Tax—though at significantly lower rates (currently €0 on short-haul flights, having been reduced from higher levels in previous years). The comparison is not quite the like-for-like disadvantage the statement suggests, though Northern Ireland’s position within the UK APD regime does create competitive pressures with Dublin Airport.
Several important questions remain unanswered in the official announcement:
- The precise APD rate that would apply to the Derry-Dublin route (likely Band A at £15 reduced rate, though this depends on aircraft configuration)
- Whether the tax cost would be absorbed by the PSO subsidy, passed to passengers, or shared
- Specific economic impact assessments quantifying the “strategic importance” claimed
- The exact wording of the New Decade, New Approach commitment regarding this specific route
- Whether any formal request for exemption was submitted and rejected, or if this reflects a policy determination without specific application
The reference to New Decade, New Approach—the 2020 agreement that restored Stormont—is significant politically, though the document’s actual provisions on air connectivity have not been quoted in available sources.
Broader significance
The dispute highlights enduring tensions in post-Brexit cross-border infrastructure planning. The Derry-Dublin route’s regulatory framework has been explicitly described as “complicated by Brexit” by Irish officials, with the PSO needing to operate outside EU regulations due to City of Derry Airport’s location outside the European Union.
City of Derry Airport has experienced growth—passenger numbers rose 23.5% to 221,000 in 2025, making it the airport’s busiest year since 2016. However, this recovery comes from a low base; the airport handled just 2.4% of Northern Ireland’s air passengers last year, down from nearly 6% in 2011. The Dublin connection is seen as crucial for reversing this decline by offering global connectivity through Dublin’s hub.
The APD question also feeds into wider debates about Northern Ireland’s competitiveness. Belfast International Airport’s chief executive has previously called for APD abolition, and a 2024 report by the Irelandia group argued the tax discourages inward tourism. The UK Government’s 2025-26 budget forecasts APD will raise £4.6 billion for the Treasury—making exemptions politically costly.
Questions to consider
- Given the UK Government’s stated openness to “conversations,” what specific mechanism might allow APD relief without creating a precedent for other cross-border routes?
- How will the additional tax burden affect passenger demand modelling for the PSO, and might it require increased Irish Government subsidy?
- Does the Minister’s call for “a fresh look at APD in the north” indicate a broader policy push, or is it specific to this route?
- What timeline exists for operator appointment, and how does regulatory uncertainty interact with the tax issue?
- How might the differing tax treatments of Derry-Heathrow (exempt) and Derry-Dublin (taxed) affect route planning and passenger behaviour?
The British Government’s position appears legally coherent under current rules but politically contentious given its own commitments to regional growth. With the route’s operational future still uncertain and no airline yet appointed, the APD dispute adds another layer of complexity to a project already navigating Brexit’s regulatory aftermath.
