Thank you for this!
We had to change plans, now we are looking at VCE-DUB and DUB-EWR on *A, all one ticket #/PNR, all in biz. Based on what you said above, it looks like we could get both US entry in DUB and luggage interlined from VCE all the way to EWR, but still wondering if we may in fact have to grab our bags in DUB and re-check to EWR while there, since that is the point of entry to the US?
