Another airline that can't leave well enough alone...
American and Iberia have ditched iconic logos - which could be recognised without any need for the airline name to be written alongside - in favour of abstract swooshes of colour which say nothing about the company name.
I see nothing wrong with the shamrock. If they want to update the livery, they should be taking a leaf out of KLM and LH's book - there's no reason why a historic logo can't be integrated in a contemporary design.
I'm also confused by the statement that "the Aer Lingus brand will remain" - surely they weren't thinking of a name change?!
