All Transatlantic routes from Ireland scrapped. Blame is being cast on the 737 Max issues, but as regular followers of this thread will know, that's only part of the story.
In terms of the airports, it represents a loss of 242K passengers at Dublin, 82K at Shannon and 28K at Cork. The Shannon figure is close to 5% of all traffic and represents a big loss. For Cork and Dublin, it's closer to 1% and will get lost in this year's growth, although the loss of Cork's only transatlantic link is symbolically important.
