6.40am so I was behind people queueing for the earlier BHX and MAN flights. I got to DUB at 5.25am and in the end had to check-in at the "Flights Closing" desk. Even then I was afraid I mightn't make as the security lines were horrible (far worse than anything I've encountered recently at LHR or in the US) although they moved along pretty quickly. If doing it again I'd definitely give myself more time.
