There have been some changes announced to Dublin Bus timetables.
I think this means that the 41A, but not the 41, and the 16 but not the 16A will serve the airport. Quite a difference if you are heading to the airport
In fact, the 41A won't head towards the city at all, if this map is correct.
Oh for the days when you could take a 41 to Drumcondra and swap to a 16A that had completed its meander through Beaumont.

Not sure of the start date for the changes.
