Hello Alinde,
Thanks for taking the trouble to reply to my post and apologies for my late response. Aer Lingus are very reticent about why they have decided to stop this route as, anecdotally and from my own experience the flights are very often 100% full. I've read (Irish Examiner) that more than 208,000 passengers traveled (return trips) to Amsterdam from Cork (Aer Lingus & KLM) in 2023, and increase from 160,000 in 2019.
From a lot of trawling through social media, and for what it's worth, this is what I know so far:
Aer Lingus is part of the IAG network, which comprises Aer Lingus, British Airways, Iberia, Vueling and Level. At Schiphol passengers who arrive from Cork and are in transit will not use BA to fly onwards (BA has only 2 routes from Schiphol, both to London). Aer Lingus would prefer these passengers to fly to London Heathrow and use British Airways to fly onwards (161 BA routes from London Heathrow).
The Amsterdam route is the third busiest out of Cork behind London Heathrow and London Stansted. Data from the Central Statistics Office shows Cork to Amsterdam grew strongly post-covid jumping from just under 160,000 passengers to and from both cities in 2019 to more than 191,000 in 2022 and more than 208,000 last year.
Best regards,
Colm O'Flynn
