Belfast International has today been sold along with Stockholm Skavsta to an American firm called ADC & HAS Airports Worldwide... It seems they have purchased the whole Abertis airport portfolio, for a mere 284 million Euros.
Luton is not mentioned and would appear to be the only airport in the Abertis portfolio left!
I would imagine an announcement on the new owner is imminent, and probably the discussions with the borough council and the terms of the airports lease are holding things this up... It would therefore appear Luton is being sold off separately. Will the new leaseholder be AENA, as many are expecting?
