Emerald Airlines, a franchise carrier of Aer Lingus, is experiencing operational difficulties due to the UK’s departure from the European Union, which has necessitated the maintenance of two separate air operator’s certificates (AOCs). Since launching in February 2022, the airline set up these dual certifications to facilitate both EU and UK domestic flights, with operations based at Dublin and Belfast.
The dual certification model has introduced significant logistical and staffing challenges. CEO Keith Butler explained that managing two AOCs and a limited pool of licensed crew has complicated operational planning, especially during aircraft on ground situations. The airline’s fleet consists of 20 ATR 72-600 aircraft, serving routes across Ireland, the UK, and France, with bases in Dublin and Belfast.
Operational Challenges and Future Plans
The airline faces ongoing issues related to staffing, as UK-based aircraft require UK-licensed personnel, and Dublin-based aircraft need EU-licensed staff. These licensing disparities hinder staffing mobility and complicate aircraft deployment. Despite these issues, Emerald Airlines remains optimistic, planning to launch an engineering apprenticeship program and exploring measures to support pilot recruitment. Passenger demand is projected to grow by 7–8% this year, with the airline maintaining profitability after two years of operation.
"Building up to 20 aircraft over a few years has been demanding, but we have achieved profitability within the second year," said CEO Keith Butler. The company continues to adapt to the regulatory environment, seeking long-term solutions to streamline its operations and personnel licensing practices, aiming for greater flexibility in the future.
