Two years later and they still haven't got their own Emirates Lounge at DUB. Probably illustrates they haven't got any growing demand for their Business and First class product on the route so I'd say that's flag enough to put your 380 rumour to bed.
Not necessary, nobody expected anything which has happened with the routes.
Jan 2012 - daily A330
Jan 2012 - B777 from July 2012
Apr 2012 - B777 from May 2012
Jan 2014 - Second daily B777 from Sep
We do know they held discussions about the A380 and daa have included it in 2015-2019 plans which final approval will happen in coming weeks.
Have other routes had loungers within the first 2 years and the current terminal set up could change which could effect plans.
