We have a booking in business with Aer Lingus from Dublin to Boston that was due to depart this morning. We have a subsequent flight almost 6 hours later from BOS to ORD with AA (separate ticket). Our EI flight has been cancelled and we have been routed to BOS via IAD.

I'm trying to call Aer Lingus but they say they're closed despite their website saying differently.

We'll be rushing to the airport, but any advice in our situation? Will they rereoute us to ORD? If not we will miss our flight to ORD with AA. We have insurance but we'd prefer to be in ORD today.
