Ok I have read this as carefully as I can. We arrive on Saturday on an international European (not DUB) flight and are going on to LAX on the A380. I take it that I have to go through security again at LHR before going off to T5C (in all probability). We have 1 hr 45 to make the connection. We are hand luggage only My only concern is if there is a lengthy queue at Flight Connections - I take it that there is no Fast Track. If that is the case should I abandon that idea and go up to the First Wing. I know that I am an old fusspot but I like to know what I might have to face and how best to deal with this. Many Thanks in advance.

BTW - the scematics and advice in this thead are marvellous. I suppose that I am putting this as some of it dates back 8
