I wouldn't mind seeing FR leave the DUB route because it much further secures EI and hopefully we could see 21x weekly and maybe 22-23 weekly from them.
Or an alternative viewpoint, the number of EI flights to NCL could stay the same, accompanied by a hefty increase in airfares to boost their bottom line. Be careful what you wish for....
I am sure the people who actually use the NCL to DUB route regularly would prefer to see the current competitive situation maintained.
