Looks like it's a go:
Aer Lingus shareholders have given the green light for a takeover by International Airline Group (IAG) at an extraordinary general meeting.
They passed four resolutions, including two on connectivity guarantees, that will allow the €1.3bn (£940m) deal to proceed.
...
IAG has also entered into agreements with competing airlines that operate long-haul flights out of the UK, the Netherlands and Ireland committing Aer Lingus to providing them with connecting passengers.
The approval comes after Ireland's low-cost carrier Ryanair on Friday accepted the bid by IAG for a near 30% stake in Aer Lingus.
IAG's plans include building a new transatlantic hub at Dublin airport.
Why a new transatlantic hub at Dublin? I think it's all about selling the C&I pre-clearance as a passenger convenience. (I can testify to the difference it makes, and I'm doing it again in September.)
