The title of the thread and the introduction should be changed, since this thread is not about travels ORIGINATING in mainland Europe, but travels that ORIGINATE in the UK but which include a TICKET with origin in mainland Europe. If you have travels which originate in the EU then this guide to the airports is not that relevant.

I know the regulars on this board like to call this kind of ex-UK trip with an ex-EU ticket an "ex-EU trip" but should everyone reading these posts and finding this thread through a search have to know than and try to understand why trips from EU airports are described in such a strange way.
