I know its not practical in the current money's-tight-just-be-thankful-to-have-a-job climate but on principle I wouldn't work at any airport stupid enough to rename itself after a dubious local hero on the back of his inevitable premature death.
To me it will always be Belfast Harbour or City as thats where it bloody well is. No such area as "George Best".
Similarly Liverpool Airport is in Speke, Not John bloody Lennon.
Sorry chaps. Rant over.
