Minidoh finnaly we can agree on somthing.The flag carriers and normal service airlines like EI,BA and BD are much better.Maybe slightly more expensive but alot better.Im not anti LCC but thats just me.Altough I have no dobuts that both airlines are very safe.
I dont really know whey Aer Lingus stopped NCL maybe low loads or they have began to concentrate more on European routes.I wouldnt be surprised to see them come back to the route as Ryanair dominate it at present and Aer Lingus returned to Bristol this year so its definitley not an impossiblity.
