Buster,
Yes - a statement on their FB page reads:
Aer Southeast will begin flights this year!
Aer Southeast is now a part of a company which has its own Airline Operating License, AOC.
It's been a long road, but a lot of work has been done behind the scenes in order to secure the operation.
Due to circumstances out of our control, which included a long period of time when Waterford airport was in deep discussions with another operator, meant that we were not in a position to progress on this matter.
However, those things have been resolved, and Aer Southeast has now picked up were it left off.
More info follows in the coming days.
The ASE team.
