Aer Lingus Regional has reported growth in passenger numbers on the two public service obligation routes it operates on behalf of the state.
Stobart Air, which operates Aer Lingus Regional, flew 33,516 passengers between Dublin and Donegal in the year to the end of October and over 51,000 between Dublin and Kerry.
The Dublin - Donegal and Dublin - Kerry routes are both served by Aer Lingus Regional, which is operated by Stobart Air.
Stobart said traffic has risen significantly since it took over the PSO routes. In 2015, when it began operating the Dublin - Donegal route, 22,022 passengers flew between the two airports. In 2014, when it took over the Donegal - Kerry PSO route, the annual traffic figure was 37,800.
The state contract for providing the service between the regional airports expires in January and will go out to tender. It cost the state €7.76m in 2014, the most recent year for which figures are available, to subsidise the two routes.
