I have booked a flight from Bangkok to Dublin, Ireland with my girlfriend in late April. We have done this trip twice before via Abu Dhabi The last 2 times we went, she had to get a UK visitors visa and a multi-entry Irish visa as she would be leaving Ireland to go north and then coming back again for the return flight. British airways told us that we need to get a transit visa for my girlfriend as we will land in London first and then connect to Dublin. So if she already has a UK visa, should she also need a transit visa to go from London to Dublin?

Can't see why you would need a transit visa. The UK visitor visa is multi-entry,

The answer is you might or might not need a transit visa!! If BA say you do, then you do!

The Irish Republic is part of the Common Travel Area and as such there is no requirement for a passport. Many airlines require you to use one anyway! On arrival at Heathrow passengers go through Immigration and therefore are subject to immigration control.

If you check the .org website 'Do I need a visa?' it states that a transit visa is required. However it then states that you may not require one if certain requirements are met. You must have a valid visa for the Irish Republic, arrive by air and have ongoing flights the same day.

As I said, you might or might not, clear as mud!

The reality is that if BA require it then it will be needed to prevent boarding being refused in Thailand.

Sorry misread the original post! If there is a valid UK visa there should not be a problem unless BA think there will be one. Still comes back to what BA say. An immigration officer might just decide the visa holders circumstances have changed!!
