One daily flight would still get people to the US but 2 flights would be better for passengers.
Aer Lingus New York and Boston flights arrive in Dublin at 5:15 and 5:20 in the morning. With a departure for 6:30 to BRS. If passengers are on the return they can still go to New York, Boston, Orlando Chicago but there would be no return for Orlando and Chicago.
Lets hope people use it to travel to the US so the 3 flights will stay.
