To a certain extent, I could understand if Ireland was held back in going to "complete" open skies until everyone else had it, BUT how is it going to adversely affect everyone else if the change in ratio goes ahead, from 1:1 to 3:1? Surely US carriers can't be happy with the status quo and having direct access to Dublin for three times as many flights can only be good?
As for EI, the uncertainty itself is costly, insofar as not knowing when it will need new acft or can introduce new routes. Please, please tell me that neither the EU and US will prevent this change; it's strangling potential and it helps absolutely no one.
