Eight Ryanair services are resuming at Shannon Airport this week.
Flights to Barcelona-Reus, Stansted, Gatwick, Kaunas, Krakow, Wroclaw, Warsaw-Modlin have been taking off and arriving at Shannon today, with a Manchester service due to start on Friday.
The airport said it will operate 18 weekly flights.
While the Government advisory notice against non-essential travel still remains in place, Shannon Airport said its workers have implemented a series of rigorous public health measures to protect the health and safety of passengers and employees at the airport.
Last month, Aer Lingus said it would permanently close its cabin crew base in Shannon in an effort to reduce costs.
81 cabin crew worked from the base and were offered either enhanced severance or where possible transfer to Dublin.
A further 45 ground staff in Shannon will remain laid off.
