Fears of summer travel chaos as Cork Airport airspace closed for seven hours

All flights at Cork Airport were halted between midnight and 7am on Wednesday.

There are fears of potential travel chaos at Irish airports over the busy summer period if incidents like this week's closure of Cork's airspace for seven hours are repeated.

The northern runway in Dublin Airport has been closed by air traffic control staff shortages 11 times so far this year, while Shannon and Cork have each been closed once.
