Make up your mind! So you DONT need a passport then?
I tried not showing it getting on a BA flight and was told “no passport no travel”!
Of course at DUB they check IDs, I am told a driving licence may suffice if British or Irish but of course I have never needed to try as a passport works best. If they suspect you are non UK/ROI national and only have a driving licence and not an EU ID, they can refuse entry.
I think.
