Can I pay to take extra baggage on a Cathay Pacific flight?
I would keep trying because when I went to the website, I could not find anything. If you do not live too far from the airport, go to the ticket counter and ask. Just make sure that you go there around 2 hours before a Cathay flight otherwise the ticket counter may not have anyone there. I would not be surprised though if you have to pay at least 50 euro.
