Very much so, Answer=42.
There is supposed to be a new round of negotiations next week (on the 17th), at which the latest US proposals are to be discussed. The US has mentioned two major obstacles: firstly Heathrow and secondly, the Irish Shannon stopover - my personal area of interest.
Aer Lingus would like to add new routes to the US and given its success in expanding into Europe, their intentions - given the right authority - can't be doubted. However, the Irish government can't be seen to be giving too much away - unless its back is up against a wall - or it will face political difficulties from the powerful Shannon lobby.
