DUB-ATL 09.25-11.15
DUB-JFK 11.35-13.15

The arrival time may change for JFK as both routes are doing an aircraft swap but with the A330 that can't happen from May.
Havn't done the exact figues but there will be an increase in seats for April,May,September,October but a slight reduction for June,July,August.
