The timing of the BA LCY services probably needs a rethink anyway. Wouldn't execs really prefer a morning departure to give them at least an afternoon in NYC, and another after 6pm to give a full day in London and New York by bedtime? If the later service had to go via Dublin T2, so what? No-one's getting off other than to do the immigration shuffle. Although the Dublin crew currently knock off at 6 after the last EI departure to the States.
