Jack1985,
I totally agree here. Aer Lingus has competitive advantage with its transatlantic business through Dublin. This will sustain the airline. Now more than ever they need to be continually developing the connectivity ex DUB as FR is intensifying competition on all of Aer Lingus' European routes.
The potential is enormous. You only need to look at EK and DXB to get a flavour of what could be achieved . However, I fear DUB may not have the required terminal make up for EI to grow at any significant pace.
