I'm sick to death of Ireland being out of Schengen!
Last night my brother-in-law was flying to Dublin from Moscow. As there are no direct flight anymore from Russia to Ireland, you have to transit somewhere.
He had booked a flight through Dusseldorf. When he tried to check in in Moscow, they said he couldn't. Dusseldorf doesn't have a transit area - he'd have to pass German emigration to check into his dublin flight, and he didn't have a Schengen visa, only an Irish one.
This is such a stupid situation! If Ireland was in Schengen, like 28 other countries (All EU, plus Switzerland, Norway and Iceland, minus Ireland and UK) it would be no problem, he could fly. If he was transiting to some other city in the EU, no problem.
Ireland needs to join Schengen!
