The lobby group Airlines for America (A4A), the main representative of U.S. carriers, has called for laws to remove the Dublin Airport (DUB) passenger cap, which it says “disproportionately impacts” American airlines.
Lobbying against the cap
The push comes as the Irish Minister for Transport, Darragh O’Brien, prepares draft legislation to eliminate the annual passenger limit of 32 million at the airport.
The Oireachtas, Ireland’s Committee on Transport, is reviewing O’Brien’s plan and will hear from community members opposing the removal of the cap next week. A4A, lobbying for major U.S. carriers including American Airlines, United and Delta, submitted its view to the committee.
“Airlines for America welcomes and supports the Minister’s legislative initiative. However, the urgency of resolving this issue cannot be overstated,” A4A stated, adding that “Irish carriers are able to more freely expand within the cap while US carriers are constrained from growth.”
The state-owned operator of the Dublin Airport has not responded to these claims by the lobby group.
Origins and court battles
Back in 2008, Dublin’s planning board set the 32 million limit to address congestion concerns in order to allow for the approval of a second terminal.
Only recently have passenger numbers begun to burst through the cap, breaching it over the last two years. While enforcement is pending in Irish and European courts, the breach has prompted the Irish Aviation Authority to begin preparing to limit flights.
A4A and the Irish-based Aer Lingus then filed a lawsuit seeking to block the caps, and were awarded a temporary win when the Irish High Court issued a stay prohibiting the caps pending resolution of the litigation.
The High Court has since asked the European Court of Justice (ECJ) to weigh in on whether the caps violate EU regulations. On Feb. 12, 2026, a court’s advocate general issued an opinion stating that the cap did not violate regulations, although this does not constitute a final decision.
Fearing the EU court would decide in favour of the cap, A4A filed a formal complaint with the U.S. Department of Transportation (DOT) in January 2026, arguing that it would breach the EU-US Open Skies Agreement.
