Looks like they won't fly DUB-YUL after A321LR delivery delays.
“Aer Lingus will not be commencing its Dublin-Montreal service as previously announced.
The later than expected delivery in 2019 of our A321LR aircraft meant that the opportunity to commence operation of the Montreal service in time for the summer season did not materialise.
Montreal will remain on our shortlisted future network plan but we do not expect to commence service on the route in the short term.”
Instead, Aer Lingus will increase existing transatlantic routes from Dublin in Summer 2020:
Orlando (MCO): Increase from 4x weekly to 6x weekly.
Miami (MIA): Increase from 2x to 3x weekly.
Seattle (SEA): Increase from 5x weekly to daily.
