In the aviation sector, there has been an 83 per cent decrease in flights handled by air traffic controlled during May 2020 compared to the same time last year according to the Irish Aviation Authority (IAA).
The IAA said Ireland was one of the worst effected countries in the European aviation network, recording only 18,290 flights during May.
