I see a lot of this will be good for T/A out of DUB and how a JV would work well.
Finnair and AA are not part of IAG and yet they have a JV agreement with BA so if Walsh was really interested in this then they could add EI to the mix without bringing them under IAG.
Besides some savings from EI HQ I don't see IAG brining a lot to EI but taking a far greater amount.
I think it's highly likely the Government will also reject it, all but FG have said they are opposed to the sale.
