Hello
I'm originally from Romania but I live with my indian husband in Ireland. He has a Stamp Eu4fam issued in Ireland. Recently we travel together in India transiting United Kingdom. On our way back to Ireland we were supposed to flight using same company and we were supposed to transit United Kingdom for 2 hours again. On the check in they denied our flight stating that my husband need transit visa even if he has a Irish resident permit.
Also we are planning to travel together to UK soon and I would like to know whether he needs any visa when we are travelling together or not?
Thank you
